Lightweight thermal insulation concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses light heat insulation concrete and a preparation method thereof. The light heat insulation concrete is formed by pouring and curing a concrete mixture; the concrete mixing material comprises the following components in parts by mass: 100 parts of water; 180 to 185 parts of cement; 34 to 36 parts of fly ash; 680 to 700 parts of aggregate; 450 to 470 parts of hollow glass beads; 2.5 to 2.7 parts of a water reducing agent; 3.3 to 3.5 parts of a reinforcing auxiliary agent; the reinforcing auxiliary agent is prepared by compounding polyvinylpyrrolidone, polyhydroxybutyrate and tributyl phosphate. The method has the advantages that the strength loss is reduced while the heat insulation performance of the concrete is improved.
本发明涉及混凝土技术领域，具体公开了一种轻质隔热混凝土及其制备方法。轻质隔热混凝土由混凝土拌和料浇筑并养护而成；混凝土拌和料包括以下质量份数的组分：水100份；水泥180‑185份；粉煤灰34‑36份；骨料680‑700份；空心玻璃微珠450‑470份；减水剂2.5‑2.7份；补强助剂3.3‑3.5份；补强助剂由聚乙烯吡咯烷酮、聚羟基丁酸酯、磷酸三丁酯复配而成。本发明具有提高混凝土隔热性能的同时减少强度损失的优点。
