Cement activation enhancer and preparation method thereof
The invention discloses a cement activation enhancer and a preparation method thereof, and belongs to the technical field of cement admixtures. The reinforcing agent is prepared from the following raw materials in parts by weight: 2-5 parts of a surfactant, 60-70 parts of a reinforcing agent, 14-20 parts of an activating agent, 10-16 parts of a thickening time control agent and 1-5 parts of a catalyst, wherein the total amount is 100 parts. According to the present invention, the basic raw materials comprise the compound alcohol amine component, the lignosulfonate, the reinforcing agent, the activating agent and other components, the catalyst using the nanometer titanium dioxide and the nanometer manganese dioxide as the main components is prepared, the early stage 3d strength of the cement is improved, and the existence of the manganese dioxide can promote the acceleration of the hydration process of the C4AF in the alkaline environment and the significant increase of the cement strength in the 28d. The raw materials act together, under the catalytic action of the nanoparticles, the activation effect is remarkable, the use amount of the cement clinker is reduced, the comprehensive performance of the cement is improved, and the application prospect is wide.
本发明公开一种水泥活化增强剂及其制备方法，属于水泥外加剂技术领域。本发明增强剂包括以下重量份的原料制备而成：表面活性剂2‑5份、增强剂60‑70份、活化剂14‑20份、调凝剂10‑16份、催化剂1‑5份，总量为100份。本发明复配醇胺组分、木质素磺酸盐、增强剂和活化剂等成分组成基本原料，制备由纳米二氧化钛和纳米二氧化锰为主要成分的催化剂，提高了水泥早期3d强度，二氧化锰的存在，可以促使C4AF在碱性环境下水化进程加快，28d时水泥强度显著增长。本发明各原料共同作用，在纳米粒子的催化作用下，活化效果显著，降低水泥熟料使用量，提升水泥综合性能，应用前景广阔。
