Environment-friendly concrete early strength agent and preparation method thereof
The invention discloses an environment-friendly concrete early strength agent which is characterized by comprising the following components in parts by weight: 4-8 parts of hyperbranched polyether containing phosphine end groups, 3-5 parts of urea/polyethylene glycol dicarboxylic acid polycondensate, 6-8 parts of volcanic ash, 10-15 parts of dolomite, 4-6 parts of 1-butyl-3-methylimidazole nitrate, 2-4 parts of tris (hydroxymethyl) methylglycine and 25-30 parts of deionized water. The invention further discloses a preparation method of the environment-friendly concrete early strength agent. The environment-friendly concrete early strength agent disclosed by the invention has a remarkable early strength effect, can be used for rapidly improving the early strength of concrete, greatly shortening the setting and hardening time of cement concrete and improving the construction efficiency, and is safe to use, environment-friendly and pollution-free.
本发明公开了一种环保混凝土早强剂，其特征在于，包括如下重量份计的各组分：含膦端基超支化聚醚4‑8份、尿素/聚乙二醇二羧酸缩聚物3‑5份、火山灰6‑8份、白云石10‑15份、1‑丁基‑3‑甲基咪唑硝酸盐4‑6份、三(羟甲基)甲基甘氨酸2‑4份、去离子水25‑30份。本发明还公开了所述环保混凝土早强剂的制备方法。本发明公开的环保混凝土早强剂早强效果显著，可快速提高混凝土早强强度、大大缩短水泥混凝土的凝结硬化时间，提高施工效率，使用安全、环保无污染。
