High-strength recycled aggregate concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses high-strength recycled aggregate concrete and a preparation method thereof.The high-strength recycled aggregate concrete comprises, by weight, 10-20 parts of cement; 20 to 25 parts of sand material; 60 to 70 parts of recycled aggregate; 40 to 50 parts of water; 20 to 30 parts of a filling body; the filling body comprises nano calcium carbonate and nano carbon fibers which are mixed according to the mass ratio of (2-9): (1-3); the preparation method comprises the following steps: S1, primarily mixing; and S2, blending. According to the high-strength recycled aggregate concrete, the porosity of recycled aggregate can be reduced, and the strength of the concrete is improved.
本申请涉及混凝土的领域，具体公开了一种高强型再生骨料混凝土及其制备方法，高强型再生骨料混凝土包含以下重量份的物质：水泥10‑20份；沙料20‑25份；再生骨料60‑70份；水40‑50份；填充体20‑30份；所述填充体包括按质量比（2‑9）：（1‑3）混合的纳米碳酸钙和纳米碳纤维；其制备方法为：S1、初混；S2、共混。本申请的高强型再生骨料混凝土能够降低再生骨料的孔隙率，提高混凝土的强度。
