High-strength recycled concrete

The invention discloses a high-strength recycled concrete. The high-strength recycled concrete is composed of, by weight, 200 to 330 parts of cement, 80 to 90 parts of ore powder, 640 to 950 parts of recycled sand, 350 to 400 parts of recycled aggregate, 70 to 80 parts of a gel material, 5 to 12 parts of a pumping aid, and 170 to 200 parts of water. Most of the above raw materials, except recycled aggregate, are recycled, so that environment protection and resource recycling are realized further. No toxic or harmful material is added; no harm is caused on human body or the environment; the strength of the obtained high-strength recycled concrete is capable of reaching C50 standard; the performance of the high-strength recycled concrete is stable; stable control of the performance of the high-strength recycled concrete can be realized via controlling the amount of cement, recycled sand, and recycled aggregate; application value is high; a preparation method is low in cost, and is capable of satisfying economic and environment protection requirements; excellent economic benefit and social benefit are achieved.
