High-performance Portland cement and preparation method thereof
The invention belongs to the field of building materials, and discloses high-performance Portland cement and a preparation method thereof. The high-performance Portland cement comprises the following components in parts by weight: 30-40 parts of cement clinker, 8-16 parts of a mixed material, 8-10 parts of gypsum, 10-20 parts of modified coal gangue, 0.2-0.4 part of a water reducing agent, 0.03-0.05 part of a waterproof agent and 0.05-0.1 part of a grinding aid. The preparation method comprises the following steps of: drying a mixed material; adding cement clinker, gypsum, modified coal gangue and grinding aid; performing grinding; adding a water reducing agent and a waterproof agent; performing homogenizing to obtain the high-performance Portland cement. The high-performance Portland cement has the advantages of being high in toughness, small in brittleness, not prone to cracking, capable of recycling coal gangue and high in impermeability.
本申请涉及建筑材料领域，具体公开了一种高性能硅酸盐水泥及其制备方法。高性能硅酸盐水泥，包括以下重量份的组分：水泥熟料30‑40份、混合材料8‑16份、石膏8‑10份、改性煤矸石10‑20份、减水剂0.2‑0.4份、防水剂0.03‑0.05份、助磨剂0.05‑0.1份；其制备方法为：将混合材料干燥后，加入水泥熟料、石膏、改性煤矸石和助磨剂，研磨，加入减水剂和防水剂，均化处理，制得高性能硅酸盐水泥。本申请的高性能硅酸盐水泥具有韧性大，脆性小，不易开裂，回收利用煤矸石，且抗渗性强的优点。
