Chemometric assessment of mechano-chemically activated zeolites for application in the construction composites
(Elsevier Sci Ltd, Oxford, 2017)
Natural zeolites of clinoptilolite type from seven deposits were submitted to mechano-chemical activation in a Retsch ultra -centrifugal mill. The zeolite types and activation parameters were altered during the experiment ...
Chemometric Analysis of Alternations in Coal Ash Quality Induced by Application of Different Mechano-chemical Processing Parameters
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2017)
The coal fly ash mechano-chemical activation conducted via high energy ultra-centrifugal mill was optimized using mathematical and statistical tools. The aim of the investigation was to accent the merits of alternations ...
Analiza uticaja sučeono zavarenih spojeva na nosivost konstrukcije rezervoara / Analysis of the effects of butt welded joints on a carrying capacity of a structure tank
(Inženjersko društvo za koroziju, Beograd, 2017)
U radu je posle proračuna metodom konačnih elemenata (MKE) analizirana raspodela napona na modelu dela oplate rezervoara pod pritiskom bez zavarenih spojeva (ZS), sa obimnim ZS, podužnim ZS i ukrsnim mestom ZS. Takođe, u ...
Electro-filter ash use in the underground coal mines
(Institut za rudarstvo i metalurgiju, Bor, 2017)
Thermal power plants in the Republic of Serbia spend 35-40 million tons of coal annually, mostly lignite, with about 6 million tons of ash or slag as a by-product of electricity and heat production, deposited on the ...
A new method of coal excavation in the complex natural-geological conditions
(Institut za rudarstvo i metalurgiju, Bor, 2017)
In the underground coal mines in Serbia, nowadays, only the pillar methods of excavation excavations, which all affect the excavation economy. This paper presents the solution of a new excavation method foreseen for ...
The influence of tailings and cement type on durability properties of self-compacting concrete
(Univ Osijek, Tech Fac, Slavonski Brod, 2017)
In order to examine the differences in chemical composition and the possibility of using mine tailings in mortar and concrete production, samples were taken from the landfill and directly from the production. Tailings test ...
Određivanje in-situ koeficijenta trenja i imperfekcije kablova za prednaprezanje / Determination of the in situ coefficient of friction and imperfection of prestressing cables
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, Beograd, 2017)
Prednaprezanjem konstruktivnih elemenata omogućava se povećavanje raspona armiranobetonskih konstrukcija. Pri projektovanju i dimenzionisanju prednapregnutih armiranobetonskih konstrukcija, neophodno je poznavanje, odnosno ...
The effect of mechano-chemical activation and surface treatment of limestone filler on the properties of construction composites
(Elsevier Sci Ltd, Oxford, 2017)
The effect of the combined actions of milling and hydrophobization procedures applied in construction composites synthesis was investigated. The mortars were prepared with cement (CEM I 42.5) and calcite aggregate complying ...
