Energy conversion in phosphate ore grain mixture activated via ultra-centrifugal mill
(Elsevier, Amsterdam, 2015)
The aim of this investigation was to establish the optimal processing parameters of the comminuted phosphate grain mixture mechanical treatment by monitoring and evaluating the activated product characteristics. An ...
Analytical modeling of activation procedure applied in alpha-alumina thermo-mechanical synthesis
(Elsevier Sci Ltd, Oxford, 2015)
The impact of the mechanical processing parameters on the alumina grain-size distribution affiliated characteristics and on the gamma to alpha phase transformation rate was investigated. The moderation in the alumina samples ...
Chemometric analysis of the influence of mechanical activation on the mica quality parameters
(Elsevier Sci Ltd, Oxford, 2015)
The differences in the set of the process parameters measured before and after mica mechanical activation and their influence on the grain size distribution related characteristics have been studied. The modification of ...
Artificial fly ash based aggregates properties influence on lightweight concrete performances
(Elsevier Sci Ltd, Oxford, 2015)
The effect of the application of pelletized fly ash based aggregates obtained through different processing techniques on the behavior of lightweight concretes was analyzed. Experimental program implied production of four ...
Mathematical approach to application of industrial wastes in clay brick production - Part I: Testing and analysis
(Elsevier Sci Ltd, Oxford, 2015)
The objective of this study was to investigate utilization potential of organic and inorganic industrial wastes in clay bricks. Mineral composition of starting heavy clay sample is tested using an X-ray diffractometer. ...
Mathematical approach to application of industrial wastes in clay brick production-Part II: Optimization
(Elsevier Sci Ltd, Oxford, 2015)
The effects of organic and inorganic waste sludges, coal dust, fly and landfill ashes, soybean crust, sawdust, sunflower flakes and their ash addition to representative heavy clay were investigated. Changes introduced to ...
Novel Utilization of Fly Ash for High-Temperature Mortars: Phase Composition, Microstructure and Performances Correlation
(Wiley, Hoboken, 2015)
In this study, the feasibility of using fly ash to manufacture high-temperature mortars was investigated. The investigation was set to define preliminary characteristics of new types of mortars based on ordinary and/or ...
Factor space differentiation of brick clays according to mineral content: Prediction of final brick product quality
(Elsevier Science Bv, Amsterdam, 2015)
Chemical composition and XRD qualitative analysis were used to calculate mineral contents of 139 brick clay raw materials using LPNORM. The second order polynomial models (SOP) for all the samples, which express the relation ...
