High-strength lightweight concrete and preparation method thereof
The invention relates to the field of lightweight concrete, in particular to high-strength lightweight concrete and a preparation method thereof. The high-strength lightweight concrete is prepared from a concrete mixture, and the concrete mixture comprises the following raw materials: Portland cement, ceramsite, a mineral admixture, water, a foaming agent, a polycarboxylate superplasticizer, polypropylene fibers, ammonium stearate and dodecyl dimethyl amine oxide. The preparation method comprises the following steps of: (1) diluting the foaming agent, and then preparing foam for later use; (2) mixing the Portland cement, the mineral admixture, the ceramsite, the polycarboxylate superplasticizer and the water to obtain slurry; (3) mixing the foam, the slurry, polypropylene fibers, the ammonium stearate and the dodecyl dimethyl amine oxide to obtain a concrete mixture; (4) pouring the concrete mixture into a mold, and aerating and hardening; and (5) performing autoclaved curing to obtain a finished product. The lightweight concrete has the advantage of improved strength.
本申请涉及轻质混凝土领域，更具体地说，它涉及一种高强度轻质混凝土及其制备方法。一种高强度轻质混凝土，由混凝土拌合料制备而成，混凝土拌合料包括以下原料：硅酸盐水泥、陶粒、矿物掺合料、水、发泡剂、聚羧酸减水剂、聚丙烯纤维、硬脂酸铵、十二烷基二甲基氧化胺；其制备方法为：步骤1)：将发泡剂稀释，然后制成泡沫，待用；步骤2)：将硅酸盐水泥、矿物掺合料、陶粒、聚羧酸减水剂、水混合，得到浆料；步骤3)：将泡沫、浆料、聚丙烯纤维、硬脂酸铵、十二烷基二甲基氧化胺混合，得到混凝土拌合料；步骤4)：将混凝土拌合料浇筑至模具内，发气硬化；步骤5)：蒸压养护，得到成品。本申请具有改善轻质混凝土的强度的优点。
