The recycled aggregate obtained by simple crushing and screening of waste concrete has a rough surface many protruding edges corners, most the is attached with old mortar, when directly used as in concrete, water demand large, strength elastic modulus are low, durability poor. Therefore, proper treatment required.This article summarizes research status pretreatment methods mechanical strengthen...

The construction sector is currently struggling with the reuse of waste originating from demolition and modernization buildings roads. Furthermore, old are gradually being replaced by new structures. This brings a significant increase concrete debris to landfills. To prevent this, many studies on possibilities recycling concrete, known as recycled aggregate (RCA), have been done. broaden applic...

The recycled aggregate permeable concrete made of reused construction wastes is very important for realizing the sustainable development industry, it can alleviate adverse impact surface runoff during storm and urban heat island effect. Therefore, this paper studied mechanical properties durability concrete. At first, a few target material, including bulk density, moisture content, water absorp...

The difficult current environmental situation, caused by construction industry residues containing ceramic materials, could be improved by using these materials as recycled aggregates in mortars, with their processing causing a reduction in their use in landfill, contributing to recycling and also minimizing the consumption of virgin materials. Although some research is currently being carried ...
