Cement activity enhancer and preparation method thereof
The invention discloses a cement activity enhancer and a preparation method thereof, and belongs to the technical field of cement additives. The reinforcing agent comprises the following raw materials in parts by weight: 10-20 parts of an alcohol amine component, 3-5 parts of urea, 1-3 parts of cane sugar, 35-50 parts of inorganic salt, 5-10 parts of an exciting agent, 3-7 parts of a water reducing component and 40-50 parts of water. The active exciting agent is added and prepared, formation of cement hydration products is accelerated, and the early strength is improved; meanwhile, sodium lauroyl glycinate is added, so that the hydration product can be promoted to be uniformly dispersed in the system, after the accelerant and the sodium lauroyl glycinate are mixed in equal proportion, an obvious synergistic effect is achieved, and finally the purposes of reducing clinker and improving the early strength and the later strength are achieved. Under the combined action of all the raw materials, the clinker proportion is greatly reduced, good excitability is achieved on fly ash type active mixed materials, the comprehensive performance of cement is effectively improved, and practical application value is achieved.
本发明公开一种水泥活性增强剂及其制备方法，属于水泥添加剂技术领域。本发明增强剂包括以下重量份的原料：醇胺组分10‑20份、尿素3‑5份、蔗糖1‑3份、无机盐35‑50份、激发剂5‑10份、减水组分3‑7份、水40‑50份。本发明添加制备活性激发剂，加速水泥水化产物的形成，提升早期强度；同时添加月桂酰甘氨酸钠可以促进水化产物在体系中的均匀分散，促进剂和月桂酰甘氨酸钠等比例混合后，呈现明显的协同作用，最终实现减少熟料，提升早期和后期强度的目的。在本发明各原料的共同作用下，大幅降低熟料配比，对粉煤灰类活性混合材有很好的激发性，水泥综合性能得到有效提升，具有实际应用价值。
