Grinding aid for improving early strength of cement and method for improving early strength
The invention discloses a grinding aid for improving the early strength of cement and a method for improving the early strength, the grinding aid is prepared from the following raw materials in parts by weight: 10-50 parts of an alcohol amine compound, 30-80 parts of a polyol compound, 20-40 parts of an inorganic salt compound, 5-10 parts of an organic sodium salt compound and 8-20 parts of molasses, and the method for improving the early strength of the cement is disclosed. In cement grinding production, a grinding aid finished product is mixed into a cement grinding head of a ball mill through a centrifugal pump, then the flow of the grinding aid is adjusted according to 0.05%-0.1% of the cement production capacity, and the grinding aid and cement raw materials enter the ball mill together to be ground to obtain a cement finished product. According to the present invention, the salt without the Cl ion is doped, such that the influence of the Cl ion on the early strength of the cement is avoided, the cement grindability can be further improved, the reasonable control of the early hydration speed of the cement is achieved, the morphology defect of the cement C-S-H gel caused by the fast early hydration speed is avoided, the high early strength is obtained, and the cement quality is improved.
本发明公开了一种提高水泥早期强度型助磨剂及提高早期强度的方法，所述助磨剂由以下重量份的原料制成：醇胺化合物10‑50份、多元醇化合物30‑80份、无机盐化合物20‑40份、有机钠盐化合物5‑10份，糖蜜8‑20份，并公开了提高水泥早期强度的方法，在水泥粉磨生产中，通过离心泵将助磨剂成品掺入到球磨机的水泥磨头中，然后按照水泥生产量的0.05％‑0.1％调节助磨剂的流量，将助磨剂与水泥原料一同进入球磨机内进行粉磨得到水泥成品。本发明掺入了不含Cl离子的盐类，避免了Cl离子对水泥早期强度的影响，还能进一步提高水泥易磨性，实现合理控制水泥早期水化速度，同时还避免早期水化速度过快造成的水泥C‑S‑H凝胶形貌缺陷，获得更高的早期强度，提高了水泥质量。
