Water-resistant light gypsum mortar
The invention relates to the field of building materials, in particular to water-resistant light gypsum mortar, which is prepared from the following raw materials in parts by mass: 40-50 parts of building gypsum powder, 40-50 parts of mineral powder, 50-80 parts of furnace slag, 5-10 parts of cement, 1-3 parts of early strength agent, 0.1-0.3 part of water-retaining agent, 0.1-0.3 part of retarder, 0.1-0.3 part of thixotropic agent and 0.3-0.5 part of organic soil. According to the water-resistant light gypsum mortar, slag is used for replacing traditional light aggregate such as vitrified micro bubbles and perlite, the physical property that the slag is high in mechanical strength is fully utilized, and the mechanical strength of the light gypsum mortar is improved; besides, the slag is a porous alkaline substance, is light in volume weight, has certain activity and can be subjected to a gelatinization reaction with the building gypsum powder in an alkaline environment, meanwhile, gypsum, the slag and cement can be subjected to a gelatinization reaction, and the mechanical strength of the light gypsum mortar is further improved.
本发明涉及建筑材料领域，具体涉及一种耐水轻质石膏砂浆，包括如下质量份的原料：建筑石膏粉40‑50份，矿粉40‑50份，炉渣50‑80份，水泥5‑10份，早强剂1‑3份，保水剂0.1‑0.3份，缓凝剂0.1‑0.3份，触变剂0.1‑0.3份，有机土0.3‑0.5份。本发明的耐水轻质石膏砂浆以炉渣代替玻化微珠、珍珠岩等传统轻骨料，充分利用了炉渣了本身机械强度较高的物理性质，提高了轻质石膏砂浆的机械强度；此外，炉渣是一种多孔性碱性物质，容重轻，且具有一定的活性，在碱性环境下可与建筑石膏粉发生胶凝反应，同时石膏、矿渣与水泥也会发生胶凝反应，进一步提高了轻质石膏砂浆的机械强度。
