Cement reinforcing agent and application thereof
The invention belongs to the technical field of cement production, and provides a cement reinforcing agent and application thereof. According to the invention, the hydration activity of blast furnace slag or fly ash in cement is stimulated by the activator, and the hydration activity is improved, so that the cement strength is improved; the complexing agent promotes structural dissociation of the slag and the fly ash and forms hydrated calcium silicate with a low Ca/Si ratio, so that the structural strength of the cement is improved; the dispersing agent enables the early hydration product to be fully dispersed to form a uniform and compact three-dimensional hydration product structure, so that the early strength and the later strength of the hardened cement paste are facilitated. Moreover, when the cement enhancer provided by the invention is applied to cement, the hydration activity of the slag and the fly ash can be effectively excited, and the quality and the performance of the cement are basically unchanged when the slag or the fly ash replaces 4-6% of cement clinker, so that the cement cost is effectively reduced, and environmental protection is facilitated.
本发明属于水泥生产技术领域，提供一种水泥增强剂及其应用。本发明通过激发剂激发水泥中高炉矿渣或者粉煤灰的水化活性，提高其水化活性，从而提高水泥强度；络合剂促进矿渣和粉煤灰结构解离，并形成低Ca/S i比的水化硅酸钙，以提高水泥的结构强度；分散剂使早期水化产物充分分散，形成均匀、致密的三维空间水化产物结构，有利于硬化水泥浆体的早期和后期强度。并且，本发明提供的水泥增强剂应用于水泥，可有效激发矿渣和粉煤灰的水化活性，使矿渣或粉煤灰取代水泥熟料4～6个百分点时，水泥的质量和性能基本不变，从而有效降低水泥成本，且有利于环境保护。
