Cement admixture and preparation method thereof
The invention discloses a cement admixture which is prepared from the following raw materials in parts by weight: 12-21 parts of silica, 11-16 parts of black rock, 68-93 parts of blast furnace slag and 0.5-2 part of grinding aid. The blast furnace slag is subjected to the following operation treatment: heating, melting, immersing in an acid solution, rapidly cooling, and immersing in the acid solution for 2-30 min to obtain a porous structure. The invention also provides a preparation method of the cement admixture. The cement admixture has good affinity with other components of cement, and the strength of blended concrete is effectively improved.
本发明公开了一种水泥掺混料，由以下重量组分的原料制备得到：硅石12‑21份、黑岩石11‑16份、高炉渣68‑93份、助磨剂0.5‑2份；所述高炉渣经过以下操作处理：经加热熔融处理并浸入酸液中急速冷却，在酸液中浸泡2‑30min，得到多孔结构。本发明还提供了上述水泥掺混料的制备方法。该水泥掺混料具备较好的与水泥其他成分之间的亲和性，有效提高了掺混后混凝土的强度。
