The invention discloses concrete for external wall thermal insulation, and relates to the technical field of building materials. The concrete is prepared from the following raw materials in parts by weight: 120 to 180 parts of cement, 80 to 100 parts of water, 30 to 40 parts of a heat preservation improver, 10 to 20 parts of glass fiber, 2 to 5 parts of a polycarboxylic acid type water reducing agent and 1 to 3 parts of a dispersing agent, the preparation method comprises the following steps: (1) preparing the cement, the water, the thermal insulation improver, the glass fiber, the polycarboxylic acid water reducing agent and the dispersing agent, and putting into a warehouse for later use; (2) transferring the raw materials in the step (1) into a stirrer for stirring and mixing, and pouring into a mold; and (3) curing the concrete in the mold in the step (2). The thermal insulation improver is introduced, so that a remarkable thermal insulation effect can be achieved, and the compressive strength and the tensile strength of the concrete are improved.
本发明公开了一种外墙保温用混凝土，涉及建筑材料技术领域。其中混凝土，以重量份计，包括以下原料：水泥：120份‑180份，水：80份‑100份，保温改进剂：30份‑40份，玻璃纤维：10份‑20份，聚羧酸系减水剂：2份‑5份，分散剂：1份‑3份；其制备方法如下：(1)准备水泥、水、保温改进剂、玻璃纤维、聚羧酸系减水剂、分散剂，放进仓库，待用；(2)将步骤(1)中各原料转移到搅拌机中进行搅拌混合，并倒入模具中；(3)对步骤(2)模具中的混凝土进行养护。本发明引入保温改进剂，能够带来显著性的隔热保温效果，且提升混凝土的抗压强度和抗拉强度。
