Gypsum-based dry-mixed mortar and preparation method thereof
The invention provides a gypsum-based dry-mixed mortar material and a preparation method thereof. The gypsum-based dry-mixed mortar material comprises low-quality gypsum clinker, a base material containing calcium oxide, sulfur, aluminum oxide, silicon oxide and the like, zeolite and quick lime. The gypsum-based mortar with excellent performance is prepared by taking the low-quality gypsum with high impurity content as a main body material; meanwhile, solidification of impurity ions (chloride ions and sodium ions) is realized, resource utilization of the low-quality gypsum is realized, and the gypsum-based mortar provided by the invention has good workability, durability and construction performance and is suitable for industrial production; wherein the dry volume weight of the gypsum-based mortar is reduced while the setting time of the gypsum-based mortar is effectively adjusted, so that the coating rate of the mortar is increased, and the crack resistance of the mortar is improved.
本申请提供了一种石膏基干混砂浆材料及其制备方法，所述石膏基干混砂浆材料包括低品质石膏熟料，含有氧化钙、硫、氧化铝和氧化硅等的基材，沸石，生石灰。本申请以杂质含量高的低品质石膏为主体材料制备出了性能优良的石膏基砂浆，同时实现了对杂质离子(氯离子、钠离子)的固化，实现了低品质石膏的资源化利用，本申请提供的石膏基砂浆具有良好的和易性、耐久性能和施工性能，在有效调整石膏基砂浆凝结时间的同时降低了石膏基砂浆的干容重，提高了砂浆的涂布率，改善了砂浆的抗裂性能。
