The invention relates to the technical field of mortar production, in particular to ground cement-based semi-self-leveling mortar and a preparation method thereof, and the ground cement-based semi-self-leveling mortar comprises the following components in parts by weight: 330-370 parts of cement, 580-620 parts of sand, 15-25 parts of fly ash, 20-30 parts of anhydrite, 1-2 parts of a defoaming agent, 2-3 parts of water reducing agent, and 0.2-0.4 part of hydroxypropyl methyl cellulose. The preparation method comprises the following steps: uniformly stirring and mixing the components according to the dosage ratio to produce the ground cement-based semi-self-leveling mortar. The semi-self-leveling mortar solves the problems of large construction difficulty and low construction efficiency caused by difficult control of the flow area or the flow speed of the self-leveling mortar in construction, has the performance between the self-leveling mortar and ground mortar, has high strength and good constructability, reduces the construction difficulty, improves the construction efficiency, and reduces the construction cost. Meanwhile, by controlling the dosage ratio of all the components, thecompressive strength and the water retention rate of the semi-self-leveling mortar are also improved, and the consistency loss rate is also reduced.
本发明涉及砂浆生产技术领域，用于增强建筑物的施工性能，尤其涉及一种地面水泥基半自流平砂浆及其制备方法，按照重量分数计包括以下组分：330‑370份的水泥，580‑620份的砂，15‑25份的粉煤灰，20‑30份的硬石膏，1‑2份的消泡剂，2‑3份的减水剂，0.2‑0.4份的羟丙基甲基纤维素；制备方法为：按照用量比将各组分搅拌混匀即可生产出该地面水泥基半自流平砂浆；解决了自流平砂浆在施工中存在流动面积或流动速度难以控制，造成施工难度大、施工效率低的问题，该半自流平砂浆的性能介于自流平砂浆和地面砂浆之间，强度高，而且施工性好，降低了施工难度，提高了施工效率，同时通过控制各组分之间的用量比，使该半自流平砂浆的抗压强度和保水率也得到了提高，还降低了稠度损失率。
