High-magnesium low-carbon cement concrete and preparation method thereof
The invention discloses high-magnesium low-carbon cement concrete, which is prepared from the following raw materials in parts by weight: 70 to 90 parts of high-magnesium low-carbon cement, 10 to 30 parts of ordinary Portland cement, 150 to 200 parts of fine aggregate, 180 to 250 parts of coarse aggregate, 30 to 50 parts of water, 1 to 3 parts of fiber, 0.5 to 1.5 parts of water reducing agent and 0.3 to 1.0 part of reinforcing agent, the high-magnesium low-carbon cement takes C2MS2 as a main mineral. On the basis of the high-magnesium low-carbon cement obtained by using the low-grade limestone and the aggregate waste residues in a large mixing amount, the reinforcing agent and the gradient carbonization curing system are further introduced, the mechanical property and the like of the obtained concrete can be effectively improved, and remarkable economic and environmental benefits are achieved.
本发明公开了一种高镁低碳水泥混凝土，各原料及其所占重量份数包括：高镁低碳水泥70‑90份，普通硅酸盐水泥10‑30份，细骨料150‑200份，粗骨料180‑250份，水30‑50份，纤维1‑3份，减水剂0.5‑1.5，增强剂0.3‑1.0份；所述高镁低碳水泥以C2MS2为主要矿物。本发明在大掺量利用低品位石灰石和骨料废渣所得高镁低碳水泥的基础上，进一步引入增强剂和梯度碳化养护制度，可有效提升所得混凝土的力学性能等，具有显著的经济和环境效益。
