Cement strength synergist and preparation method thereof
The invention relates to the technical field of cement enhancement, and particularly discloses a cement strength synergist, which is prepared from the following raw materials in percentage by weight: 10 to 15 percent of triethanolamine, 5 to 10 percent of diethanol amine, 5 to 10 percent of triisopropanolamine, 8 to 15 percent of amino trimethylene phosphonic acid, 5 to 10 percent of sodium tripolyphosphate, 0 to 5 percent of xanthan gum and the balance of water. The cement strength synergist is a liquid cement additive, is mainly composed of an alcohol amine substance, an auxiliary substance and a conditioning agent, is green and nontoxic, does not contain chloride ions, does not rust reinforcing steel bars, has excellent durability, and does not damage cement; the cement grinding aid is added into raw materials in a dropwise manner during cement grinding, the mixing amount is 0.03%-0.1%, the fineness of cement particles can be improved, the specific surface area of the cement particles can be increased, static electricity can be eliminated, the cohesiveness of the cement particles can be improved, and the machine-hour yield can be increased; the 3-day strength and 28-day strength of the cement are obviously improved.
本发明涉及水泥增强技术领域，具体公开了一种水泥强度增效剂，所述水泥强度增效剂包括以下重量百分比原料：三乙醇胺10～15％，二乙醇胺5～10％，三异丙醇胺5～10％，氨基三甲叉膦酸8～15％，三聚磷酸钠5～10％，黄原胶0～5％，余量为水。本发明水泥强度增效剂是一种液体水泥外加剂，主要由醇胺类物质、辅助物质、调节剂组成，绿色无毒，不含氯离子，对钢筋无锈蚀耐久性优良，对水泥无损害；在水泥粉磨时以滴加的形式加入原料中，掺量为0.03％‑0.1％，可以提高水泥颗粒的细度，增大水泥颗粒的比表面积，消除静电，改善水泥颗粒的粘聚性，提高台时产量；对水泥的3天、28天强度均有明显的提高。
