Study of montmorillonite and cationic activators sistem rheological characteristic change mechanism
(Elsevier Sci Ltd, Oxford, 2007)
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 ...
Compressive strength and microstructure of ordinary cured and autoclaved cement-based composites with mechanically activated kaolins
(Elsevier Sci Ltd, Oxford, 2018)
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 ...
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 ...
The effect of alternations in mineral additives (zeolite, bentonite, fly ash) on physico-chemical behavior of Portland cement based binders
(Elsevier Sci Ltd, Oxford, 2018)
Instrumental analyses accompanied by analytical modeling tools were employed to assess physico-chemical changes induced by variations in chemical composition of cementitious composites, i.e. mortar binders. Coal combustion ...
Optimization of bentonite clay mechano-chemical activation using artificial neural network modeling
(Elsevier Sci Ltd, Oxford, 2017)
The properties of seven montmorillonite-rich bentonites of different geological origin were investigated prior and subsequent to mechano-chemical processing in an ultra-centrifugal mill. The objective of the experiment was ...
Optimization of drying through analytical modeling: clays as bonding agents in refractory materials
(Elsevier Sci Ltd, Oxford, 2016)
The objective of this study was to investigate the clay drying as a unit operation in the refractory materials processing. Two clays that varied in chemical and mineralogical compositions were experimentally tested in a ...
Effects of mechanical-activation and TiO2 addition on the behavior of two-step sintered steatite ceramics
(Elsevier Sci Ltd, Oxford, 2019)
Steatite, as ceramic with composition predominantly resting on magnesium silicate, was produced from economic resources - talc, aluminosilicate clays, and either BaCO3 or feldspar as flux. Titanium dioxide was a doping ...
Comprehensive approach to the influence of frequently used secondary raw materials on clay bricks quality using mathematical modeling (a systematic review)
(Elsevier Sci Ltd, Oxford, 2018)
The main idea of this research was to evaluate rice and sunflower hulls, sawdust and their ashes, as additives in clay brick production using mathematical analysis. All available papers, containing the parameters of interest, ...
Comparative kinetic study of mechanical activation process of mica and talc for industrial application
(Elsevier Sci Ltd, Oxford, 2014)
Mica and talc have wide areas of application as a raw material in a number of industrial branches. Mechanically activated mica has specific applications such as: capacitors, insulators, and pearlescent pigments. Talc is ...
Influence of different bonding and fluxing agents on the sintering behavior and dielectric properties of steatite ceramic materials
(Elsevier Sci Ltd, Oxford, 2017)
The focus of the study was on providing insights into interconnections between sintering and development of the crystalline microstructure, and consequently variations in dielectric behavior of four steatites fabricated ...
