Gypsum-based spraying mortar
The invention provides gypsum-based spraying mortar. The gypsum-based spraying mortar is prepared from the following raw materials in parts by weight: 75 to 85 parts of phosphorus building gypsum powder, 1 to 5 parts of glass chopped fiber, 5 to 10 parts of mixed aggregate, 5 to 10 parts of cement, 2 to 3 parts of slaked lime, 2 to 5 parts of quick lime, 1 to 5 parts of fly ash and 5 to 10 parts of chemical additive, the glass chopped fibers are added, gaps among ardealite crystals are filled with the glass fibers, meanwhile, the glass fibers are good in tensile property, the breaking strength of the mortar is improved, the breaking strength of the mortar with the glass fibers added is greatly improved, the aggregate is the mixed aggregate composed of the lightweight aggregate, the fine sand and the coarse aggregate, and therefore the lightweight ardealite mortar has the advantages that the lightweight ardealite mortar is high in strength and good in durability. On the basis of the fine sand, the vitrified micro beads and the blast furnace cinder are added, so that the sprayed mortar is high in water retention rate, strong in base layer bonding force, free of shrinkage and high in sagging resistance, hollowing and cracking of the mortar are effectively avoided, and the engineering quality is improved.
本发明提供了石膏基喷筑砂浆，石膏基喷筑砂浆包括以下重量份数配比的原料：磷建筑石膏粉75‑85组份，玻璃短切纤维1‑5组份、混合骨料5‑10组份、水泥5‑10组份、熟石灰2‑3组份、生石灰2‑5组份，粉煤灰1‑5组份、化学添加剂5‑10组份；本发明添加有玻璃短切纤维，玻璃纤维的存在填补了磷石膏晶体间的空隙，同时玻璃纤维的抗拉性能好,提升了砂浆的抗折强度，使得加人玻璃纤维后的砂浆抗折强度大幅提升，且本申请的骨料采用由轻骨料、细沙和粗骨料组成的混合骨料，以细沙为基础，添加玻化微珠和高炉烧渣，喷筑砂浆保水率高，基层粘接力强、不收缩，抗流挂性高，有效避免砂浆空鼓、开裂，改善工程质量。
