What is recycled aggregate? What is it?
The aggregate made of waste concrete in construction waste through crushing and screening is called recycled aggregate. This kind of aggregate has rough surface, angular, large specific surface area and high water absorption. Therefore, when it is used to prepare concrete, the unit water consumption is larger than that of ordinary concrete, and the slump loss of concrete is also large. The strength and elastic modulus of recycled aggregate concrete are equivalent to 2/3 of that of natural aggregate concrete.
