High-heat-preservation heat-insulation light-weight high-strength concrete and preparation method thereof
The invention provides high-heat-preservation heat-insulation light-weight high-strength concrete and a preparation method thereof, and solves the problems of low strength, difficulty in construction and the like of heat-preservation heat-insulation concrete. The high-heat-preservation heat-insulation light-weight high-strength concrete is prepared from the following raw materials in percentage by weight: 20 to 35 percent of cement, 30 to 45 percent of ceramsite, 15 to 25 percent of glass beads, 3 to 5 percent of miscanthus fiber, 0.5 to 1.5 percent of water reducing agent, 0.8 to 1.5 percent of foaming agent and 8 to 15 percent of water. The specific preparation method comprises the following steps: uniformly mixing and stirring 20-35% of cement, 30-45% of ceramsite and 15-25% of glass beads to obtain a dry material A; dissolving 0.5-1.5% of a water reducing agent and 0.8-1.5% of a foaming agent in 8-15% of water, uniformly stirring, adding into the dry material A, and mixing and stirring to obtain slurry B; 3-5% of pre-saturated miscanthus fiber is scattered into the slurry B, and the mixture is stirred evenly to obtain the high-heat-preservation heat-insulation light-weight high-strength concrete. The concrete has the advantages of low raw material cost, simple preparation method, light weight and high strength while meeting high thermal insulation property.
本发明提供一种高保温隔热轻质高强混凝土及其制备方法，解决保温隔热混凝土强度低，难施工等问题。本发明高保温隔热轻质高强混凝土的原材料按以下重量百分比组成：20‑35％水泥，30‑45％陶粒，15‑25％玻化微珠，3‑5％芒草纤维，0.5‑1.5％减水剂，0.8‑1.5％发泡剂，8‑15％水。具体制备方法为：将20‑35％水泥，30‑45％陶粒和15‑25％玻化微珠混合搅拌均匀得到干料A；将0.5‑1.5％减水剂，0.8‑1.5％发泡剂溶于8‑15％水中搅拌均匀，加入到干料A中混合搅拌得到浆料B；将3‑5％预饱和后的芒草纤维分散撒入浆料B内，搅拌均匀得到高保温隔热轻质高强混凝土。本发明具有原材料成本低，制备方法简单，混凝土在满足高保温隔热性的同时还具有轻质高强的优点。
