Fluorine gypsum self-leveling mortar and preparation method thereof
The invention belongs to the technical field of building materials, and particularly relates to fluorgypsum self-leveling mortar and a preparation method thereof.The fluorgypsum self-leveling mortar comprises raw materials and additives, and the raw materials comprise, by weight, 300-700 parts of fluorgypsum; 300 to 700 parts of quartz sand; the admixture comprises the following components in parts by weight: 1.0-3.0 parts of a water-retaining agent; 0.5 to 1.0 part of a defoaming agent; 0.5 to 4.0 parts of a water reducing agent; the self-leveling mortar meeting the related performance requirements of JC/T 1023-2021 Gypsum-based self-leveling mortar is prepared by adjusting the proportion of the additive and adjusting the formula of the self-leveling mortar. According to the present invention, the consumption of the natural resources can be reduced, the production cost of the self-leveling mortar can be reduced, the solid waste resource utilization level can be improved by using the fluorgypsum and other solid wastes, the fluorgypsum and the sulfate coagulation accelerator can react to generate ettringite and other hydration products, the coagulation time of the self-leveling mortar can be shortened, and the self-leveling mortar has characteristics of environmental protection and environmental protection. The early strength of the self-leveling mortar is improved.
本发明属于建筑材料技术领域，具体涉及一种氟石膏自流平砂浆及其制备方法，包括原材料和外加剂：所述原材料包括按重量份计的如下组分：氟石膏：300～700份；石英砂：300～700份；所述外加剂包括按重量份计的如下组分：保水剂：1.0～3.0份；消泡剂：0.5～1.0份；减水剂：0.5～4.0份；稳定剂：0.3～0.5份，通过外加剂配比调整与自流平砂浆配方调整制备出满足JC/T 1023‑2021《石膏基自流平砂浆》相关性能要求的自流平砂浆；能够减少天然资源消耗，降低了自流平砂浆的生产成本，同时还通过利用氟石膏等固体废弃物，提高固废资源化利用水平，还能通过氟石膏中与硫酸盐类促凝剂反应生成钙矾石等水化产物，缩短自流平砂浆的凝结时间，提高自流平砂浆的早期强度。
