Porous thermal insulation concrete material based on solid waste comprehensive utilization recycled aggregate and preparation method of porous thermal insulation concrete material
The invention discloses a porous thermal insulation concrete material based on solid waste comprehensive utilization recycled aggregate, which is prepared from the following ingredients in parts by weight: 40 to 50 parts of ordinary Portland cement, 60 to 80 parts of solid waste comprehensive utilization recycled aggregate, 5 to 10 parts of phase change materials, 80 to 100 parts of machine-made sand, 3 to 6 parts of coconut fiber, 2 to 7 parts of polyvinyl alcohol fiber and 5 to 10 parts of nanometer silicon dioxide. The phase change material is an expanded vermiculite encapsulated capric acid composite material, and the mass ratio of expanded vermiculite to capric acid is 1: (0.5-0.8); the solid waste comprehensive utilization recycled aggregate is a mixture of tailings, waste perlite particles and EPS particles; the mass ratio of the tailings to the waste perlite particles to the EPS particles is 8: 2: (0.01-0.03). The concrete material provided by the invention not only has good thermal insulation performance, but also has excellent mechanical properties.
本发明公开了一种基于固废综合利用再生骨料的多孔保温混凝土材料，以重量份计，包括以下组分：普通硅酸盐水泥40‑50份，固废综合利用再生骨料60‑80份，相变材料5‑10份，机制砂80‑100份，椰壳纤维3‑6份，聚乙烯醇纤维2‑7份，纳米二氧化硅5‑10份，所述相变材料为膨胀蛭石封装癸酸复合材料，所述膨胀蛭石、癸酸的质量比为1：0.5‑0.8；所述固废综合利用再生骨料为尾矿、废珍珠岩颗粒、EPS颗粒的混合物；所述尾矿、废珍珠岩颗粒、EPS颗粒的质量比为8：2：0.01‑0.03。本发明提供的混凝土材料不仅保温性能好，且力学性能佳。
