AB  - The effects of two different mechanically activated kaolins, AKV (61% kaolinite, 14% quartz and 16% mica) and AKG (51.6% kaolinite and 40.6% quartz) on the compressive strength of cement composites and microstructure of pastes were investigated. Composite mixtures, in which 10, 20, 30, 40 and 50% of ordinary Portland cement (OPC) was replaced by AKV or AKG, were prepared with w/b of 0.5, and exposed to different curing conditions (ordinary curing for 28 days and autoclaving). Factors affecting microstructure were investigated on pastes by X-ray diffraction (XRD), Differential thermal analysis/thermal gravimetry (DTA/TG) analyses. Mercury intrusion porosimetry (MIP) and Scanning electron microscopy with Energy-dispersive spectroscopy (SEM-EDS). AKG composites exhibited higher compressive strengths under both curing conditions. Positive autoclaving effects on strengths were predominantly pronounced at the higher cement replacement levels. Comparison of the autoclaved and ordinary cured paste microstructure, revealed more intensive pozzolanic reaction during autoclaving conditions (CH content near zero) and higher total porosity. The negative effect of hydrogarnet on the strength was compensated by the formation of the crystalline tobermorite. Obtained results revealed that mechanically activated kaolin, with high content of quartz, could be a promising pozzolanic addition, even at high cement replacement levels (30-50%), especially when autoclaving curing conditions were applied.

AB  - Kaolin from a Serbian deposit, having a high content of mica and quartz, disordered kaolinite and a high specific surface area, was used to prepare metakaolin (MK). The calcination at temperatures of 700 degrees C or 750 degrees C for 30 to 180 min resulted in MK having high pozzolanic activity, but also significant aglomeration of particles. In order to disperse aglomerates, MK was milled, which resulted in increased pozzolanic activity and reduced particle size. The effects of MK and additionally milled metakaolin (MKmill) on the composite strengths and microstructure of the pastes were compared. We prepared and investigated composites in which ordinary Portland cement (OPC) was replaced with 10% to 50% of MK or MKmill, as well as the representative samples of paste for determination of microstructure. Compressive strengths higher than the control were obtained for composites having up to 30% of MK and up to 40% of MKmill, respectively. Increase of composite strengths with MKmill was more pronounced at lower cement replacement levels (10% and 20%). Compressive strength of composites containing agglomerated MK were satisfactory, which suggests that milling of MK, as well as purification of kaolin, may not be necessary.

AB  - Environmental concerns and sustainable development require increased replacement of cement. Most of previous studies have shown that the compressive strength of cement-based composites is maximized with a 20% content of metakaolin. We investigated composites prepared by replacing ordinary Portland Cement (OPC) with 30 to 50% of metakaolin (MK) and addition of appropriate amount of hydrated lime, which were ordinary cured for 2, 28 or 90 days. Hydration products and microstructure of the pastes were determined by X-ray diffraction (XRD), differential thermal analysis/thermal gravimetry (DTA/TG) and mercury intrusion porosimetry (MIP). MK was produced by calcination of kaolin from a Serbian deposit, which contained a high level of impurities. Replacement of OPC with 30% of MK achieved 28 days compressive strength equivalent to that of the control mix. Higher replacement levels, 40% and 50%, combined with the addition of hydrated lime, achieved satisfactory relative strengths of 94% and 87%, respectively. The positive contribution was particularly pronounced after 90 days for a composite containing 50% of MK. The results clearly showed a possibility of obtaining composites having acceptable compressive strength with reduced cement content in accordance with environmental and sustained development requirements.

AB  - The effects of thermally (MK) or mechanically activated kaolin (AK) on the compressive strength of mortars and microstructure of pastes were investigated. Mortar mixtures, in which 10%, 20% and 30% of ordinary Portland cement (OPC) was replaced by either MK or AK, were prepared (w/b of 0.5) and ordinary (age 2, 28 or 90 days) and autoclave cured. Hydration products were determined by X-ray diffraction (XRD) and differential thermal analysis/thermal gravimetry (DTA/TG) analysis, while microstructure was investigated by mercury intrusion porosimetry (MIP). MK substitution increases the compressive strength of ordinary-cured mortars, as a result of the higher content of reactive silica that caused more pronounced pozzolanic reaction, as well as by effective refinement of their pore structure. Positive effects on the compressive strength could be achieved up to 30% substitution of OPC by MK The OPC substitution by AK resulted in lower strengths of ordinary-cured mortars, compared to both MK mortars and reference. Higher specific surface area and finer particles of AK were insufficient to compensate, through filler effect, lower pozzolanic reaction and additional negative influence of the kaolinite presence. The highest compressive strength was obtained for mortar with 10% of AK (relative strength of 94%). In comparison to the reference, autoclaved MK and AK mortars, exhibited lower compressive strength, as a consequence of increasing the hydrogarnet formation, instead of tobermorite. The highest strength was achieved for mortar with 10% of AK.

AB  - Kaolin from a Serbian deposit, characterized by high content of impurities, such as mica and quartz, disordered kaolinite and high specific surface area, was subjected to thermal and mechanical activation on a large scale. Activations were carried out with a goal to investigate the effects of applied methods on the chemical, structural and morphological changes that occurred in the kaolin, and their influence on the pozzolanic activity. The changes were monitored using XRD, FTIR, TG/DTA, PSD, BET and SEM analyses. Pozzolanic activity was evaluated by determination of the 7-day compressive strength conducted on the lime mortars. The results showed that mechanical activation by milling the kaolin for 20 h in the conventional horizontal ball mill was competitive for obtaining pozzolana as thermal activation. Pozzolanic activity of thermally activated kaolin was mainly influenced by formation of metakaolin. Combined effects (such as significant specific surface area increase, as well as partial kaolinite and complete mica phase amorphization) were dominant in pozzolanic activity of mechanically activated kaolin.

AB  - Metakaolin composite cements were prepared with 5 to 35 % replacement of ordinary Portland cement with metakaolin (MK), manufactured by thermal activation/calcination of domestic kaolin clay, and commercial matakaolin (CMK). Performance of the composite cements was evaluated through the setting time (initial and final), compressive strengths (for ages 2, 7, 28, 90 and 180 days) and soundness, and compared with control cement (Portland cement - CEM I). After 28 days, compressive strength was higher than that for control cement for cements prepared with addition of CMK, and with addition of up to 25 % MK.

AB  - U radu su prikazani rezultati istraživanja dobijanja metakaolina termičkim tretmanom domaće kaolinske gline. Polazna sirovina je bila kaolinska glina sa ležišta Vrbica (Aranđelovački basen), čiji je sadržaj kaolinita oko 80% i gubitak žarenjem 12,33%. Diferencijalnom termičkom analizom (DTA/TGA) utvrđeno je da do dehidroksilacije i transformacije kaolinita u metakaolinit dolazi u opsegu temperature 450-700°C. Proces kalcinacije je praćen termičkim tretmanom kaolinske gline u laboratorijskim uslovima na temperaturama 550, 600, 650 i 700°C, različito vreme: 15, 30, 60, 90, 120, 150 i 180 min. Kao glavni kvantitativni kriterijum za ocenu ponašanja kaolinita u procesu kalcinacije, korišćen je stepen dehidroksilacije materijala, Dtg. Optimalni parametri procesa kalcinacije, pri kojima je postignut stepen dehidroksilacije 0,97, jesu: temperatura 650°C i vreme zagrevanja 90 min. Transformacije kaolinita u metakaolinit potvrđene su rendgenskom strukturnom analizom i IR spektroskopijom polazne gline i termički tretiranih glina. Na difraktogramima termički tretiranih glina nisu uočeni karakteristični pikovi kaolinita, dok IR spektri pokazuju odsustvo karakterističnih veza kaolinita. Pucolanska aktivnost metakaolina, određena direktnom metodom, pri optimalnim uslovima kalcinacije iznosi 0,65 g Ca(OH)2 / g metakaolina. Na osnovu ovih istraživanja može se zaključiti da je kaolinska glina sa nalazišta Vrbica pogodna za proizvodnju metakaolina, odgovarajuće pucolanske aktivnosti, a koji se može primenjivati u svojstvu dopunskog cementnog materijala u sistemima na bazi cementa.
AB  - The metakaolin was produced by thermal treatment (calcination) of the starting high-quality kaolin clay from Serbia. The optimal calcination parameters, for which nearly complete dehydroxylation of the material was achieved, are: temperature 650°C and heating time of 90 min. The conversion of the kaolinite to metakaolinite was confirmed by XRD and IR analyses of the starting and thermally treated kaolin samples. The pozzolanic activity was determined by Chapelle test. The obtained value 0.65 g Ca(OH)2/g of metakaolin indicates that produced metakaolin may be used as supplementary cementitious material.

AB  - One of the globally accepted principles in the Sustainable Development Strategy is sustainable production and consumption which are including environmental, material and energy efficiency in each stage of production of goods and services, starting from design, production, to primary and secondary use and recycling and disposal. Portland cement is a pre-eminent construction material which world production exceeds 2 billion t per year. Despite this success, the industry faces challenges related to improved durability and enhanced performance while at the same time improving the sustainability of production. Portland cement is not environmentally very friendly material. The production of 1t of portland cement requires 1.6 t of raw materials, primarily good quality limestone and clay. Also, production of 1t of portland cement clinker is said to create approximately 1t of CO2 and other greenhouse gases (GHG) and requires lots of fuels and energy. The cement industry is fully aware of their part of the responsibility in implementing all the necessary measures and over the past decades, has been actively involved in seeking ways to consume less energy and natural resources, and emit less CO2 per unit of cement produced. Cement industry can significantly contributes to the sustainable development by continuously reducing the CO2 emission from cement production by increased use of biofuels and alternative raw materials as introducing modified low-energy clinker types and cements with reduced clinker content. .

AB  - Environmental concerns coming from the high energy consumption and CO2 emission associated with cement production have brought about pressures to reduce cement consumption through the use of new materials which can be applied for substitution of a part of clinker in Portland cement or a part of cement in concrete. One of the materials that satisfy requirements of sustainable development and, when added in appropriate shares, improves the properties of cement, mortars and concrete, is metakaolin (MK), a processed pozzolana. The main and widely used raw material for production of metakaolin is kaolin clay. MK is produced by calcination or "thermal activation" of kaolin clay. The possibilities for metakaolin production are strongly related to the characteristics of the used kaolin clay. The samples of domestic kaolin clay used in this study were provided by factories Kaolin, Valjevo, and Keramika, Mladenovac. Chemical composition, mineralogical composition and thermal properties of these samples were determined. Thermal analysis (simultaneous recording of TG, DTG and DTA signals) was carried out at the temperature range from 20 to 1200 degrees C. For both clays the results show that the loss of mass occurred in two stages. The dehydroxillation of kaolinite and formation of metakaolin occurred in the second stage. Minerals quartz and kaolinite are dominant in the clay Kaolin, Valjevo. Dehydroxillation of kaolinite and formation of metakaolin took place in the temperature range 350-800 degrees C. This clay does not have clearly distinct exothermic and endothermic peaks. Clay from Keramika, Mladenovac, has a higher content of the kaolinite mineral, i.e. 81.51%. The dehydroxillation of kaolinite and fori-nation of metakaolin occured in the temperature range 400-700 degrees C. This clay has two distinct endothermic peaks at 60 and 490 degrees C. All these results show that both clays can be used for production of metakaolin.

The main and widely used raw material for production of metakaolin is kaolin clay. MK is produced by calcination or "thermal activation" of kaolin clay. The possibilities for metakaolin production are strongly related to the characteristics of the used kaolin clay. The samples of domestic kaolin clay used in this study were provided by factories Kaolin, Valjevo, and Keramika, Mladenovac. Chemical composition, mineralogical composition and thermal properties of these samples were determined. Thermal analysis (simultaneous recording of TG, DTG and DTA signals) was carried out at the temperature range from 20 to 1200 degrees C. For both clays the results show that the loss of mass occurred in two stages. The dehydroxillation of kaolinite and formation of metakaolin occurred in the second stage. Minerals quartz and kaolinite are dominant in the clay Kaolin, Valjevo. Dehydroxillation of kaolinite and formation of metakaolin took place in the temperature range 350-800 degrees C. This clay does not have clearly distinct exothermic and endothermic peaks. Clay from Keramika, Mladenovac, has a higher content of the kaolinite mineral, i.e. 81.51%. The dehydroxillation of kaolinite and fori-nation of metakaolin occured in the temperature range 400-700 degrees C. This clay has two distinct endothermic peaks at 60 and 490 degrees C. All these results show that both clays can be used for production of metakaolin.",

AB  - The aim of this work is to examine changes of the montmorillonite mineral rheological characteristics during its activation with sodium carbonate and magnesium hydroxy carbonate. In order to foresee the mechanism of these processes, it was necessary to study the following: The change of the rheological characteristics of the investigated system, i.e. viscosity and thixotropy, with respect to the initial montmorillonite and water system, structural changes caused by migration of Al3+ ions from the octaedric positions into the interlamellar region, by using the structural analysis methods and by monitoring the cation exchange capacity increase during the activation of this mineral, formation of the new anionic clay types, as well as their synthesis and structure in an independent system and formation and emergence of new structures during particle interaction, during which various products are created, in the form of "card house", "band type", "networked band type" or connected by a "latching" mechanism. The changes in rheological characteristics has been studied for the montmorillonite obtained from "Jelenkovac" bentonite by separating fractions smaller than 2 mu m, with Ca2+ and Mg2+ mostly being the exchangeable cations.

AB  - For the most part of portland cements produced in Serbia belong to the group of mixed cements that are produced in processing of the portland cement clinker with addition of different amounts of mineral additives. The mineral additives with the widest application in the cement industry of Serbia are granulated slag of blast furnace, natural and industrial pozzolana and limestone. Numerous of mineral additives are by-products and, therefore, the advantages of mixed cement production are lower price of final product, saving of energy, reduction of gas emission, and reduction of amount of disposed solid waste. With the aim of integration domestic cement industry into the European trends, cement producers manufacture the cement in accordance with the European standard JUS EN 197-1. On the basis of the previous investigations, it could be concluded that mineral additives used in this research satisfy quality requirements according to the standard regulation of JUS EN 197-1. Test results of phisico-mechanical characterization of portland cement prepared with the mineral additives (granulated slag of blast furnace, limestone and industrial pozzolana) are shown in this paper.

AB  - Metakaolin (MK) je termički aktiviran alumino-silikatni materijal visoke pucolanske aktivnosti. Dodatkom mata-kaolina cementu poboljšava se kvalitet koji se manifestuje kroz: povećanje čvrstoće, skraćenje vremena vezivanja (da li je ova karakteristka prednost ili ne zavisi od primene cementa) sniženje autogenog skupljanja, kontrolu alkalno-silikatne reakcije, smanjenje rizika od korozije čelika izazvane hloridima i poboljšanje trajnosti betona. Zbog toga, metakaolin postaje značajan dopunski materijal za proizvodnju betona visokih performansi.
AB  - Metakaolin (MK) is thermally activated alumino-silicate material with high pozzolanic activity. MK is quite useful in improving concrete quality, such as enhancing strength, shortening setting time (whether this characteristic is advantageous depends on the application of cements), decreasing autogenous shrinkage, controlling alkali aggregate reaction, reducing risk of chloride-induced corrosion of embedded steel and improving the durability of concrete. Therefore, MK is a promising supplementary material for manufacturing high-performance concrete.

AB  - Najveći deo proizvodnje cementa u Srbiji, približno 95%, su standardizovani mešani cementi na bazi Portland cementnog klinkera kome se dodaju mineralni dodaci: granulisana zgura visoke peći, prirodni i industrijski pucolani krečnjak i gips. Cilj ispitivanja je bio da se odredi mineraloški i hemijski sastav mineralnih dodataka koje domaće fabrike cementa koriste u svojoj redovnoj proizvodnji, jer oni mogu značajno doprineti kvalitetu i osobinama proizvedenih cemenata.
AB  - The most of the cements production in Serbia, approximately 95 per cent, are standardized blended Portland cements based on Portland cement clinker mixed with mineral admixtures such as granulated blast furnace slag, natural and industrial pozzolana, limestone and gypsum. The aim of investigation were to determines mineral and chemical composition of the mineral admixtures which domestic cement factories uses in their regular production as their quality can great contribute to the quality of the cements produced.
