Anti-cracking cement
The invention discloses anti-cracking cement and belongs to the field of building materials. According to the technical scheme, the cement-based material is characterized by comprising the following raw materials in parts by weight: 100 parts of ordinary Portland cement, 10-20 parts of silica fume, 15-25 parts of fly ash, 5-10 parts of polyvinyl alcohol fibers, 20-30 parts of bentonite, 3-9 partsof an anti-cracking reinforcing agent and 1.2-2.3 parts of a water reducing agent. The effect of reducing generation of internal cracks of the cement-based material is achieved.
本发明公开了一种抗开裂水泥，属于建筑材料领域，其技术方案要点是原料按重量份包括普通硅酸盐水泥100份、硅灰10‑20份、粉煤灰15‑25份、聚乙烯醇纤维5‑10份、膨润土20‑30份、抗开裂增强剂3‑9份、减水剂1.2‑2.3份，达到降低水泥基材料内部裂纹产生的效果。
