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 ...
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 ...
The study of thermal behavior of montmorillonite and hydromica brick clays in predicting tunnel kiln firing curve
(Elsevier Sci Ltd, Oxford, 2017)
The aim of this study was to test montmorillonite and hydromica type of brick clays by using simultaneous thermal analysis and dilatometry in an assessment of the suitability of brick clays to produce building elements. ...
Effects of mechanical activation on the parameters of talc quality for ceramics production - Chemometric approach
(Elsevier Sci Ltd, Oxford, 2015)
Talc is broadly used in the ceramic materials industry, either as a basic raw material, or as filler, due to its chemical inertia, fragmentation proneness, thermal stability, and refractoriness. The mechanical activation ...
