High-strength anti-crack mortar and preparation method thereof

The invention relates to the technical field of building materials, and provides high-strength anti-crack mortar and a preparation method thereof.The high-strength anti-crack mortar is prepared from, by weight, 80-90 parts of cement, 85-95 parts of sand, 5-10 parts of fly ash, 8-15 parts of sodium silicate, 8-12 parts of molybdenum disulfide, 0.3-0.6 part of hydroxyethyl cellulose ether, 0.01-0.15 part of a water reducing agent and 60-70 parts of water. By means of the technical scheme, the problems that in the prior art, mortar is low in strength and poor in cracking resistance are solved. 本发明涉及建筑材料技术领域，提出了一种高强度抗裂砂浆及其制备方法，高强度抗裂砂浆，包括以下重量份的组分：水泥80~90份、砂85~95份、粉煤灰5~10份、硅酸钠8~15份、二硫化钼8~12份、羟乙基纤维素醚0.3~0.6份、减水剂0.01~0.15份、水60~70份。通过上述技术方案，解决了现有技术中的砂浆的强度较低、抗开裂性较差的问题。
