dc.descriptionReady-mixed concrete manufacturers, in hot weather regions like the Gulf area, are faced with drops in compressive strengths of concrete produced in summer. High ambient temperatures increases the rate of evaporation from fresh concrete resulting in lower effective water content and hence lower effective water-cement ratio per weight [1-2]. As shown in figure (1), a reduction of compressive strength has also been observed on specimens produced under controlled environment and tested in laboratoryen_US
dc.description.abstractUsing hot aggregates in concrete making results in drop in compressive strength of the produced concrete. Various methods have been proposed for cooling concrete aggregates. In this paper we propose a modified design for a cooling drum to be used in this regard. Preliminary simulation of the heat flow during the cooling process in the drum is analyzed with the objective of optimizing the design and achieving minimum cooling time with the least possible power. A finite element model for the new design is proposed and discussed. Many of the challenges facing the numerical simulation are addressed. The results of the finite element analysis of the modified design are presented and compared with similar ones in the literature.en_US
