Abstract
Using hot aggregates, in concrete production, results in a drop in compressive strength of the produced concrete. Various methods have been proposed for cooling concrete aggregates. This paper proposes 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. Challenges facing numerical simulation are addressed in this paper. The results of the finite element analysis of the modified design are presented and compared with the original design.
