| description | The invention relates to the technical field of building materials, and particularly discloses anti-cracking recycled concrete and a preparation method thereof. The anti-cracking recycled concrete is prepared from the following raw materials in parts by weight: 450 to 700 parts of recycled coarse aggregate, 400 to 550 parts of fine aggregate, 150 to 250 parts of cement, 80 to 120 parts of water, 50 to 75 parts of fly ash, 50 to 75 parts of slag powder, 5 to 10 parts of water reducing agent, 15 to 35 parts of tannic acid and 10 to 25 parts of hydroxyapatite. The preparation method comprises the following steps: mixing the recycled coarse aggregate, the fine aggregate, the cement, the water, the fly ash, the slag powder, the water reducing agent, the tannic acid and the hydroxyapatite, and stirring to obtain the anti-cracking recycled concrete. The anti-cracking recycled concrete prepared by the invention has good anti-cracking performance and relatively high compressive strength.
