Machine-made sand concrete using synergist and preparation method of machine-made sand concrete
The invention discloses machine-made sand concrete using a synergist and a preparation method of the machine-made sand concrete. The concrete comprises the following components and a formula: 395-435parts of cement; 0-30 parts of fly ash; 0-30 parts of mineral powder; 900.15-920.55 part of machine-made sand; 864.85-884.45 parts of broken stone; 9.1-9.9 parts of an additive; 2.73-2.97 parts of a synergistic agent; and 153-170 parts of water. The synergist component comprises a reinforcing agent, a dispersing agent, nano calcium carbonate, a foaming agent, a foam stabilizer and water. Accordingto the invention, the inherent advantages of the machine-made sand are brought into full play, and the problem of shortage of natural sand resources is effectively relieved; use amount of cement in the same grade of machine-made sand concrete can be reduced and the strength of the machine-made sand concrete is not changed or even higher, the durability of the machine-made sand concrete is improved, the cost of the machine-made sand concrete is reduced, and the cracking risk of the concrete can be reduced.
本发明公开了一种使用增效剂的机制砂混凝土及其制备方法，该混凝土的成分和配方如下：水泥395‑435份；粉煤灰0‑30份；矿粉0‑30份；机制砂900.15‑920.55份；碎石864.85‑884.45份；外加剂9.1‑9.9份；增效剂2.73‑2.97份；水153‑170份，所述增效剂组分包括增强剂、分散剂、纳米碳酸钙、起泡剂、稳泡剂以及水，本发明将机制砂的固有优势充分发挥，有效缓解天然砂资源短缺问题。能够降低同等级机制砂混凝土水泥用量，同时保证机制砂混凝土强度不变甚至更高，提高机制砂混凝土耐久性，不仅降低机制砂混凝土成本，还可降低混凝土开裂的风险。
