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 ...
What to expect from heavy clay?
(Elsevier Sci Ltd, Oxford, 2013)
The need of testing the quality of brickclay arises in all brick factories, with the opening of new deposits. The analyses are both time and economically consuming, so the aim of this study was to shorten the procedure ...
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 ...
Prediction and fuzzy synthetic optimization of process parameters in heavy clay brick production
(Elsevier Sci Ltd, Oxford, 2013)
Many factors influence final clay brick properties, since the raw materials used are highly heterogeneous. Statistical analysis is rarely used, according to literature, but it would improve understanding of the overall ...
Sensitivity analysis of mathematical models for final product properties: Link to DTG curve
(Elsevier Sci Ltd, Oxford, 2013)
Compressive strength and water absorption of fired heavy clay products varies with firing temperatures, but not entirely according to linear function, as it is mostly reported in literature. Also, differential thermo-gravimetric ...
ANN model of brick properties using LPNORM calculation of minerals content
(Elsevier Sci Ltd, Oxford, 2014)
Mineralogical composition of heavy clays is one of the most important properties when stadying raw materials in brick industry. Within this study, quantitative determination of minerals using LPNORM calculation was performed, ...
Mechanically activated coal ash as refractory bauxite shotcrete microfiller: Thermal interactions mechanism investigation
(Elsevier Sci Ltd, Oxford, 2014)
A growing demand for refractory castables with advanced properties has given rise to a continuous technological evolution and highlighted the necessity for secondary raw materials reapplication even in refractory industry. ...
Assessment of intensive grinding effects on alumina as refractory compound: Acceleration of gamma to alpha phase transformation mechanism
(Elsevier Sci Ltd, Oxford, 2014)
In this study, the feasibility of alumina phase transition enhancement by mechanical activation was conducted. It was showed that the milling environment plays an important role on the physical, chemical and thermal behavior ...
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 ...
