Multipurpose concrete reinforcing agent and preparation method thereof
The invention discloses a multipurpose concrete reinforcing agent which comprises the following raw materials in parts by weight: 14-25 parts of metakaolin; 1-3 parts of a defoaming agent; 30 to 60 parts of alcohol amine organic matter; 15 to 40 parts of polyol; 3 to 7 parts of 1, 2-propylene glycol; 2-6 parts of an antioxidant; 3-7 parts of a rare earth aluminate coupling agent; 1-3 parts of an expanding agent; 2-5 parts of a dispersant; 40 to 70 parts of cellulose nanofiber; 50 to 85 parts of steel fiber; 1-3 parts of a preservative; 2-4 parts of a coagulant aid; 25-35 parts of an organic binder, and 100-300 parts of water. The concrete has the beneficial effects that the rare earth aluminate coupling agent, the cellulose nanofibers and the steel fibers are added into the formula, and the rare earth aluminate coupling agent can obviously improve the interface action between organic matters and the concrete, so that the bonding strength between a raw material mixture of the concrete and stones can be improved; the cellulose nanofibers and the steel fibers have high tensile strength and have the effect of synergistically improving the mechanical strength of the concrete, so that the reinforcing agent can be applied to porous concrete and recycled concrete.
本发明公开了一种多用途的混凝土增强剂，包括以下重量份分数配比的原料：偏高岭土14‑25份；消泡剂1‑3份；醇胺类有机物30‑60份；多元醇15‑40份；1，2‑丙二醇3‑7份；抗氧化剂2‑6份；稀土铝酸酯偶联剂3‑7份；膨胀剂1‑3份；分散剂2‑5份；纤维素纳米纤维40‑70份；钢纤维50‑85份；防腐剂1‑3份；助凝剂2‑4份；有机粘结剂25‑35份、水100‑300份。本发明有益效果：在配方中添加稀土铝酸酯偶联剂、纤维素纳米纤维和钢纤维，稀土铝酸酯偶联剂可以明显改善有机物与混凝土之间的界面作用，可提高混凝土的原料混合料和石子时间的粘接强度，纤维素纳米纤维和钢纤维的抗拉强度高具有协同提高混凝土力学强度的作用，使得该增强剂可用在多孔混凝土和再生混凝土。
