High-toughness fiber-reinforced building material and preparation method thereof

The invention discloses a high-toughness fiber-reinforced building material and a preparation method thereof. The material is prepared from, by weight, 10-20 parts of polymeremulsion, 30-50 parts of cement, 15-25 parts of fly ash, 6-12 parts of colliery powder, 4-10 parts of composite reinforced fiber, 1-5 parts of dispersing agent, 2-5 parts of water reducing agent, 0.5-3.5 parts of thickener and12-18 parts of water. According to the high-toughness fiber-reinforced building material, the toughness and the anti-cracking effect of the material can be improved, the cement, the fly ash and the composite reinforced fiber are uniformly distributed with the dispersing agent, the mechanical property is changed, the deformation resisting capacity of the material is significantly improved, and theprobability that the building material cracks and is broken is lowered. 本发明公开了种高韧性纤维增强建筑材料及其制备方法，包括以下重量份数的原料组成：聚合物乳液10-20份、水泥30-50份、粉煤灰15-25份、煤矸石粉6-12份、复合增强纤维4-10份、分散剂1-5份、减水剂2-5份、增稠剂0.5-3.5份和水12-18份。本发明提出的高韧性纤维增强建筑材料，可提高了材料的
