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 ...
Concrete paving blocks and flags made with crushed brick as aggregate
(Construction and Building Materials, 2012)
Demolition of old buildings in urban cores has produced a large amount of waste material. Since they are mostly masonry structures the largest part of the waste material is ceramic waste. Besides that, ceramic waste is ...
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 ...
Failure investigation of the bucket wheel excavator crawler chain link
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
The high mobility of open pit machines in heavy duty conditions provides fertile ground for the occurrence of various failures of the traveling mechanisms' vital parts such as chain links. The goal of the study presented ...
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 ...
Numerical simulation of fatigue crack propagation: A case study of defected steam pipeline
(Pergamon-Elsevier Science Ltd, Oxford, 2019)
In order to prevent the premature failure of steam pipeline produced of molybdenum-vanadium steel, the experimental tests were performed to measure fracture toughness and to determine the mechanical behaviour of cracked ...
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 ...
