Recycled concrete with waste clay bricks as replaced coarse aggregates and preparation method of recycled concrete
The invention discloses recycled concrete with waste clay bricks as replaced coarse aggregates and a preparation method of the recycled concrete. The recycled concrete comprises water, cement, sand, broken stone and waste bricks according to the weight ratio of 1 to 2.1-2.5 to 2.9-3.2 to 4.7-5.3 to 0.6-1.1. The preparation method includes the steps of calculating the ratio, preparing the materials, preparing the waste bricks, and conducting crushing through a jaw crusher, wherein the crushing particle size is controlled within the range of 20 mm to 50 mm; screening aggregates after breaking, wherein screening is conducted through a screen with the aperture of 50 mm first, residues on the screen continue to be crushed, then the crushed residues are screened through a screen with the aperture of 20 mm, and residues on the screen are kept; throwing in the materials to be stirred. The recycled concrete has the advantages that the recycled concrete is optimal in replacement rate, high in strength, excellent in material mechanical property, environmentally friendly, low in carbon emission, easy to prepare and the like, and the materials of the recycled concrete can be conveniently obtained.
