Experiment Research on the Use of Recycled Brick Aggregate

A large number of waste brick is hard to use among undisposed construction and demolition waste. Recycled aggregate made with waste brick was used to prepare mortar for concrete tiles in the research. Flexural strength of mortar made with both natural and recycled aggregate was studied. The influences of processing control coefficients are considered as well.
