Preparation method of anhydrous anhydrite lightweight self-leveling mortar
The invention provides a preparation method of anhydrite lightweight self-leveling mortar. The desulfurized gypsum, the ash cement, the self-made light gypsum sand, the II-type anhydrite and the auxiliary agent are stirred and mixed according to a specific ratio, the volume density of the obtained anhydrite self-leveling mortar is 800-1000 Kg/m < 3 >, the 28d absolute dry compressive strength is 31-40 MPa, which is far greater than the 28d absolute dry compressive strength (20 MPa) of the existing self-leveling mortar, and the prepared anhydrite self-leveling mortar has the advantages of high strength, good water resistance, good water resistance and the like. The light gypsum sand which is high in strength, waterproof, environment-friendly and low in manufacturing cost is mixed into the formula, so that the manufacturing cost of the self-leveling mortar is greatly reduced.
本发明提供一种无水硬石膏轻质自流平砂浆的制备方法。通过将特定配比的脱硫石膏、灰水泥、自制的轻质石膏砂、II型无水硬石膏和助剂搅拌混合，得到的无水硬石膏自流平砂浆的体积密度在800Kg/m3‑1000Kg/m3之间，28d绝干抗压强度为31MPa‑40MPa，远远大于现有的自流平砂浆的28d绝干抗压强度(20MPa)，其中使用了一种具有高强、耐水、环保且造价低的轻质石膏砂掺入配方中，极大的降低了自流平砂浆的造价。
