Desulfurized gypsum fly ash self-leveling mortar
The invention discloses desulfurized gypsum fly ash self-leveling mortar in the field of building materials, the self-leveling mortar is prepared by mixing and stirring a cementing material, fine aggregate, desulfurized gypsum, fly ash, an additive and water, based on the total mass of the cementing material, the additive amount of the fine aggregate is 56-58% of the total mass of the cementing material, and the additive amount of the desulfurized gypsum is 10-20% of the total mass of the cementing material. The addition amount of the desulfurized gypsum is 10%-50% of the total mass of the cementing material, the addition amount of the fly ash is 10%-50% of the total mass of the cementing material, the addition amount of the additive is 0.4%-0.8% of the total mass of the base material, and the addition amount of the water is 34%-36% of the total mass of the base material. According to the scheme, the cement is used as a main material, the desulfurized gypsum, the fly ash and the additive are added to prepare the desulfurized gypsum and fly ash self-leveling mortar, and the adhesiveness and viscosity of the self-leveling mortar are improved by designing the proportion of the desulfurized gypsum, the fly ash and the additive, so that the material is easier to use and construct; and after the self-leveling mortar is cured, the anti-cracking performance and the moisture-proof performance are improved.
本发明公开了建筑材料领域的一种脱硫石膏粉煤灰自流平砂浆，自流平砂浆由胶凝材料、细骨料、脱硫石膏、粉煤灰、外加剂和水混合搅拌所制，以胶凝材料的总质量为基准，细骨料的添加量为胶凝材料总质量的56％‑58％，脱硫石膏的添加量为胶凝材料总质量的10％‑50％，粉煤灰的添加量为胶凝材料总质量的10％‑50％，外加剂的添加量为基料总质量的0.4％‑0.8％，水的添加量为基料总质量的34％‑36％。本方案以水泥为主材料，添加脱硫石膏、粉煤灰及外加剂，制备脱硫石膏粉煤灰自流平砂浆，通过设计脱硫石膏、粉煤灰和外加剂的配比，改善自流平砂浆的黏附性和粘性，从而使材料更加易于使用和施工，使自流平砂浆固化后抗裂性能、防潮性能提高。
