Low-temperature composite cement early strength agent and preparation method thereof
The invention discloses a low-temperature composite cement early strength agent, which is prepared from the following raw materials in parts by mass: 10 to 15 parts of calcium formate, 0.2 to 0.4 part of triethanolamine, 5 to 8 parts of modified halloysite nanotubes, 4 to 6 parts of magnesium-aluminum hydrotalcite, 3 to 5 parts of nano calcium carbonate, 1 to 2 parts of cellulose ether and 0.3 to 0.5 part of anionic surfactant. The invention also discloses a preparation method of the low-temperature composite cement early strength agent. The cement early strength agent disclosed by the invention not only has a good low-temperature early strength effect, but also can improve the later strength of cement, and is free of chlorine salt and sulfate, and the durability of a cement product is good.
本发明公开了一种低温复合水泥早强剂，包括下述质量份的原料：甲酸钙10‑15份、三乙醇胺0.2‑0.4份、改性埃洛石纳米管5‑8份、镁铝水滑石4‑6份、纳米碳酸钙3‑5份、纤维素醚1‑2份、阴离子表面活性剂0.3‑0.5份。本发明还公开了低温复合水泥早强剂的制备方法。本发明的水泥早强剂不仅具有良好的低温早强效果，而且能提升水泥的后期强度，而且不含氯盐、硫酸盐，水泥制品的耐久性好。
