Thermal insulation concrete and preparation method thereof
The invention relates to the technical field of concrete preparation, and particularly discloses thermal insulation concrete and a preparation method thereof. The thermal insulation concrete is prepared from the following raw materials in parts by weight: cement, fly ash, lime, a foaming agent, a water reducing agent, water, mineral cotton fibers and modified expanded perlite, wherein the modifiedexpanded perlite is prepared by carrying out surface modification on expanded perlite by using a silane coupling agent. The preparation method comprises the following steps: mixing and stirring the slag cotton fiber and the modified expanded perlite to obtain a material d; adding cement and fly ash into the material d to obtain a material e; dissolving a water reducing agent and a foaming agent into 1-2kg of water to prepare an admixture solution; adding the residual water into the material e, and uniformly stirring to obtain a material f; spraying the additive solution into the material f inan atomization form, and uniformly stirring the materials. The prepared concrete has good thermal insulation performance.
本申请涉及混凝土制备的技术领域，具体公开了一种保温混凝土及其制备方法。保温混凝土包含以下重量份的原料制成：水泥、粉煤灰、石灰、发泡剂、减水剂、水、矿渣棉纤维、改性膨胀珍珠岩、所述改性膨胀珍珠岩是由硅烷偶联剂对膨胀珍珠岩进行表面改性制得的。其制备方法为：将矿渣棉纤维和改性膨胀珍珠岩混合搅拌、得到料d；将水泥、粉煤灰加入到料d中，得到料e；将减水剂、发泡剂溶于1‑2kg的水中，制成外加剂溶液；将剩余的水加入到料e中，搅拌均匀，得到料f；将外加剂溶液通过雾化形式喷入料f，搅拌均匀。制备的混凝土具有较好的保温性能。
