High-strength lightweight thermal insulation concrete and preparation method thereof
The invention discloses high-strength lightweight thermal insulation concrete and a preparation method thereof. The product is prepared from the following raw materials in parts by weight: 25-40 partsof cement, 15-20 parts of fly ash, 30-40 parts of aggregate, 0.5-1 part of polystyrene particles, 1-2 parts of a foaming agent, 0.5-1.5 parts of a water reducing agent, 8-12 parts of water, 1-1.5 parts of steel fiber and 1-1.5 parts of polypropylene fiber, and is good in thermal insulation effect, light in wall body and high in strength. The preparation method comprises the following steps: uniformly mixing and stirring aggregate and steel fibers; adding cement and fly ash into a material c, and adding water into the material c to obtain a material d; adding polystyrene particles and polypropylene fibers into the material d to obtain a material e; and preparing a mixed aqueous solution from a water reducing agent and a foaming agent, uniformly stirring, spraying the mixed aqueous solutioninto the material e in an atomization form, and uniformly stirring to prepare the high-strength lightweight thermal insulation concrete. The concrete prepared by the method has the advantages of goodthermal insulation effect, light wall body and high strength.
本发明公开了一种高强轻质保温混凝土及其制备方法，所述产品由包含以下重量份的原料制成：水泥25‑40份；粉煤灰15‑20份；骨料30‑40份；聚苯乙烯颗粒0.5‑1份；发泡剂1‑2份；减水剂0.5‑1.5份；水8‑12份；钢纤维1‑1.5份、聚丙烯纤维1‑1.5份，具有保温效果好、墙体轻且强度高的优点；制备方法是将骨料和钢纤维混合搅拌均匀；将水泥、粉煤灰加入到料c中，再将水加入到料c中，得到料d；将聚苯乙烯颗粒和聚丙烯纤维加入到料d中，得到料e；将减水剂、发泡剂制成混合水溶液，搅拌均匀，通过雾化形式喷入料e内，搅拌均匀，制成高强轻质保温混凝土；此方法制备的混凝土，具有保温效果好、墙体轻和强度高的优点。
