Introduction It is a hot potato problem to dispose more and more scrap concrete and need settle urgently for the government of each country.In the paper,for crushing and grading the waste concrete blocks,according to a certain percentage of mixed aggregate called by the recycled aggregate or recycled concrete aggregate,and recycled aggregate as part or all of the preparation of the preparation of recycled aggregate concrete is recycled concrete aggregate effective way to use one.Waste concrete used in structural engineering must be tested throughoutly by theregeneration of a solid experiment and reliable theoretical basis,This paper will research the mechanics performance of recycled concrete material in compression.
