Desulfurized gypsum fly ash self-leveling mortar

Abstract

The application discloses a kind of desulfurization gypsum fly ash self-leveling mortar in the field of building materials, and self-leveling mortar is prepared by mixing and stirring cementitious material, fine aggregate, desulfurization gypsum, fly ash, additive and water, with the total mass of cementitious material as the basis, the addition amount of fine aggregate is 56%-58% of the total mass of cementitious material, the addition amount of desulfurization gypsum is 10%-50% of the total mass of cementitious material, the addition amount of fly ash is 10%-50% of the total mass of cementitious material, the addition amount of additive is 0.4%-0.8% of the total mass of base material, and the addition amount of water is 34%-36% of the total mass of base material.The scheme uses cement as the main material, adds desulfurization gypsum, fly ash and additive, prepares desulfurization gypsum fly ash self-leveling mortar, and by designing the ratio of desulfurization gypsum, fly ash and additive, the adhesion and viscosity of self-leveling mortar are improved, so that the material is more easy to use and construct, and the crack resistance and moisture resistance of self-leveling mortar after solidification are improved.
