Proportioning method of special gypsum-based self-leveling mortar for floor heating backfilling
The invention relates to the technical field of mortar proportioning methods, in particular to a proportioning method of special gypsum-based self-leveling mortar for underfloor heating backfilling. According to the gypsum-based self-leveling mortar, Portland cement and gypsum are used as basic cementing materials, quartz sand, perlite and epoxy resin are used as aggregates, water is used as a solvent, citric acid waste residues are used as a retarder, fly ash and cellulose ether are used as water reducing agents, wollastonite powder is used as a reinforcing agent, and zeolite powder is used as a displacer. The gypsum-based self-leveling mortar comprises a defoaming agent. Certain cement can be replaced under the action of the zeolite powder, so that the concrete performance can be improved, the cement can be saved, and the cost can be reduced. The zeolite powder is added into the cement, so that the stability of the cement can be better improved, and the problem that when the gypsum-based self-leveling mortar is used, a large amount of water needs to be injected to dissolve cement, raw materials are greatly wasted, the strength is relatively low, and cracks occur after long-time use is effectively prevented.
本发明涉及砂浆配比方法技术领域，具体为一种地暖回填专用石膏基自流平砂浆配比方法，所述石膏基自流平砂浆以硅酸盐水泥和石膏为基础胶凝材料，石英砂、珍珠岩和环氧树脂为骨料，以水为溶剂，以柠檬酸废渣为缓凝剂，以粉煤灰和纤维素醚为减水剂，以硅灰石粉为增强剂，以沸石粉作为置换剂，所述石膏基自流平砂浆包含有消泡剂。本发明通过沸石粉的作用能置换一定的水泥，可改善混凝土性能的同时还可节约水泥降低成本，在水泥中加入沸石粉可以更好的完善水泥的稳定性，有效防止了石膏基自流平砂浆进行使用时，需要注入大量的水和水泥进行溶和，大大的浪费了原材料的同时，强度也相对较低，长时间使用下会出现裂缝的情况的问题。
