Lightweight concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses lightweight concrete which comprises the following components in parts by weight: 350-400 parts of Portland cement, 70-80 parts of fly ash, 500-600 parts of sandstone, 20-30 parts of a foaming agent, 2-3 parts of an additive, 5-10 parts of a polyurethane elastomer and 110-120 parts of water. The preparation method comprises the following steps: 1, adding the raw materials according to the proportion, mixing and stirring uniformly to obtain concrete slurry; 2, uniformly mixing foam generated by foaming of a foaming agent with an air entraining agent to obtain a foaming material; 3, mixing and stirring the concrete slurry and the foaming material to be uniform, and then performing pouring curing treatment; 4, curing the concrete subjected to curing treatment to obtain the lightweight concrete. The lightweight concrete provided by the invention can be used in cold and hostile places, and has the advantage of freezing and thawing resistance.
本申请涉及混凝土的领域，具体公开了一种轻质混凝土，包括以下重量份数的组分：硅酸盐水泥350～400份、粉煤灰70～80份、砂石500～600份、发泡剂20～30份、外加剂2～3份、聚氨酯弹性体5～10份、水110～120份。其制备方法为：步骤1：将原料按照比例添加混合搅拌均匀，得到混凝土浆体；步骤2：将发泡剂进发泡产生的泡沫与引气剂混合均匀，得到发泡料；步骤3：将混凝土浆体和发泡料混合搅拌均匀，然后浇筑养护处理；步骤4：养护处理后的混凝土固化后得到轻质混凝土。本申请的轻质混凝土可用于温度寒冷恶劣的地方，其具有抗冻融的优点。
