Research on Flexural Performance of Concrete Components in Prefabricated Buildings

The use of recycled concrete can reduce the extraction of natural aggregates, achieve the reuse of construction waste, and thus achieve environmental protection and economic cost savings. In terms of mechanical properties, the use of recycled materials has the effect of reducing the strength and durability of concrete. Diamond sand has high hardness and good durability, and the addition of concrete can effectively improve the strength of concrete. However, there is little research on the content of diamond sand added. This study aims to add diamond sand to recycled concrete and test the effect of diamond sand content on the flexural performance of recycled concrete under the same recycled material content by changing the content of diamond sand. The aim is to make a certain contribution to the optimization of prefabricated structures.
