Properties of Cementitious Materials with Recycled Aggregate and Powder Both from Clay Brick Waste

The utilization of recycled brick aggregate (RBA) and powder (RBP) in cementitious materials helps the reclamation clay waste construction demolition waste. This work studied properties with RBA as RBP supplementary material. has lower apparent density higher water absorption than natural aggregate, an irregular micro-structure contains high content silicon aluminum oxides possesses excellent pozzolanic activity. Incorporating decreases fluidity increases setting time, but incorporated improves pore structure average diameter materials, thereby decreasing permeability. Utilizing drying shrinkage, while shrinkage materials; mortar 50% 30% common without RBP. high-volume mechanical strength, there is no obvious decrease strength for Moreover, flexural to compressive ratio incorporating. transport, transport incorporation; incorporating appropriate can obtain low Particularly, a significant chloride ingress occurs substitution
