Additive for improving early strength of low-heat cement
The invention discloses an additive for improving the early strength of low-heat cement, and belongs to the technical field of additives. The additive comprises the following components in parts by mass: 25-35 parts of alcohol amine, 15-20 parts of a nanocrystalline seed material, 5-10 parts of a cactus extracting solution, 10 parts of polybasic sugar alcohol, 5 parts of a dispersing agent and 5 parts of a defoaming agent. The admixture contains the alcohol amine, the nanocrystalline seed material, the cactus extracting solution, the polybasic sugar alcohol and the like, so that the 3d strength and 28d strength of the low-heat cement can be effectively improved, and meanwhile, the early hydration heat release is not increased.
本发明公开了一种提高低热水泥早期强度的外加剂，属于外加剂技术领域。本发明的外加剂，包括以下质量份数的组分：醇胺25～35份、纳米晶种材料15～20份、仙人掌提取液5～10份、多元糖醇10份、分散剂5份和消泡剂5份。本发明的外加剂中含有的醇胺、纳米晶种材料、仙人掌提取液和多元糖醇等组分，能够有效提高低热水泥3d和28d的强度，同时不增加早期的水化放热量。
