Cement-based self-leveling mortar based on Yellow River sediment and preparation method of cement-based self-leveling mortar
The invention belongs to the technical field of self-leveling mortar, and particularly discloses cement-based self-leveling mortar based on Yellow River sediment and a preparation method of the cement-based self-leveling mortar. The preparation method of the cement-based self-leveling mortar based on the Yellow River sediment comprises the following steps: mixing 30-130 parts of the Yellow River sediment, 15-120 parts of river sand, 5-50 parts of fly ash, 20-100 parts of Portland cement, 40-90 parts of water and 0.05-5 parts of a stabilizer, and curing to obtain the cement-based self-leveling mortar. The Yellow River silt can reduce hydration heat release and self-constriction of cement, and the cracking risk of the self-leveling mortar is reduced. The stabilizer improves the water-retaining property of the mortar and reduces water evaporation at the same time. An alkaline environment generated after cement hydration is beneficial to chemical reaction between the Yellow River silt and the cementing material, so that the strength of the mortar is consolidated. The prepared self-leveling mortar is good in mechanical property, small in shrinkage amount, convenient in material taking, low in cost and suitable for various environments.
本发明属于自流平砂浆技术领域，具体公开了一种基于黄河泥沙的水泥基自流平砂浆及其制备方法。本发明所述基于黄河泥沙的水泥基自流平砂浆的制备方法为将黄河泥沙30～130份、河砂15～120份、粉煤灰5～50份、硅酸盐水泥20～100份、水40～90份、稳定剂0.05～5份混合，经养护得到。本发明中黄河泥沙能够减少水泥水化放热和自收缩，降低自流平砂浆开裂风险。稳定剂提高了砂浆的保水性，同时降低了水分蒸发。水泥水化后产生的碱性环境，有利于黄河泥沙与胶凝材料发生化学反应，巩固砂浆的强度。本发明制备的自流平砂浆力学性能好，收缩量小，取材方便，成本低，可适用于各种环境。
