The invention discloses a concrete early strength agent which comprises the following components in parts by weight: 20-30 parts of calcium chloride, 10-15 parts of calcium nitrite, 8-10 parts of calcium nitrate, 5-8 parts of triethanolamine, 3-5 parts of hydroxymethyl cellulose, 5-6 parts of a polycarboxylate superplasticizer, 5-8 parts of nano silicon dioxide, 5-6 parts of diatomite and 3-5 parts of methacrylic acid. The concrete early strength agent provided by the invention can accelerate the hardening time of concrete, and has a reinforcing effect on the later strength of a cement base material.
本发明公开了一种混凝土早强剂，包括按重量份数计的如下成分：氯化钙20‑30份、亚硝酸钙10‑15份、硝酸钙8‑10份、三乙醇胺5‑8份、羟甲基纤维素3‑5份、聚羧酸减水剂5‑6份、纳米二氧化硅5‑8份、硅藻土5‑6份、甲基丙烯酸3‑5份。本发明提供的混凝土早强剂，可加快混凝土硬化时间，对水泥基材后期强度具有增强作用。
