The invention discloses recycled concrete, which is prepared from the following raw materials in parts by weight: 450 parts of cement, 200 parts of water, 710 parts of recycled aggregate, 5 parts of a water reducing agent, 500 parts of sand, 25 parts of fly ash and 210 parts of gravel. According to the invention, the coarse aggregate in the concrete adopts the construction waste, is hard in texture and not prone to deformation, and can inhibit the drying shrinkage amount of cement paste and reduce concrete deformation; and the tension-compression ratio and the bending-compression ratio of the recycled concrete are consistent with the strength value of common concrete.
本发明公开了一种再生混凝土，按照重量份计，由以下原料制备而成：水泥450份，水200份，再生骨料710份，减水剂5份，沙子500份，粉煤灰25份，碎石210份。本发明混凝土中的粗骨料采用建筑废弃物，其质地坚硬、不易变形，可以抑制水泥浆体的干燥收缩量，减少混凝土变形；再生混凝土的拉压比和折压比与普通混凝土的强度值一致。
