Utilization of Clay Brick Waste Powder for Partial ...

2020-4-14  Abstract. Partial replacement of cement with crushed burnt clay brick waste powder (CBP) could reduce CO 2 emission, enhance the conservation of natural resources, and decrease the cost of waste disposal sites. The aim of this study is to investigate the use of CBP as a partial replacement for cement in the production of cement mortar.
