Low-cost gypsum-based self-leveling material
The invention discloses a low-cost gypsum-based self-leveling material . The low-cost gypsum-based self-leveling material is prepared by mixing the following raw materials: desulfurized gypsum alpha gypsum powder, fly ash, an exciting agent, a water reducing agent, a defoaming agent, a suspension stabilizer, a water-retaining agent, rubber powder, a water repellent and a retarder. According to the present invention, the power plant desulfurization by-product desulfurization gypsum and the solid waste fly ash are adopted as the main raw materials, such that the resource utilization of the solid waste is achieved, the machine-made sand or the river sand is not required, the quartz sand ore or the natural river sand is not required, the energy is saved, the carbon emission is reduced, and the environmental resource pressure is relieved; and the obtained low-cost gypsum-based self-leveling material product is low in cost, good in fluidity and high in flexural and compressive strength, and all indexes are higher than the requirements specified by the existing industrial standard JC/T1023-2021 Gypsum-based self-leveling Mortar.
一种低成本石膏基自流平材料，由以下原料混配制成：脱硫石膏α石膏粉，粉煤灰，激发剂，减水剂，消泡剂，悬浮稳定剂，保水剂，胶粉，憎水剂和缓凝剂。本发明以电厂脱硫副产物脱硫石膏和固体废弃物粉煤灰为主要原料，实现了固体废物的资源化利用，且无需使用机制砂或者河砂，不需开采石英砂矿或者天然河砂，节能，并减少碳排放，缓解环境资源压力，所得低成本石膏基自流平材料产品不仅成本低，而且流动度佳，抗折抗压强度高，各项指标均高于现行行业标准JC/T1023‑2021《石膏基自流平砂浆》规定的要求。
