The invention provides lightweight concrete, belonging to the technical field of concrete. The additive for a lightweight concrete plate comprises the following raw materials in percentage by mass: 20-30% of polypropylene fibers, 20-30% of latex powder, 20-30% of a water reducing agent, 20-30% of a swelling agent and 20-30% of mineral powder. The invention further provides preparation methods of the concrete and a concrete plate. The concrete and the concrete plate provided by the invention have high compressive strength and high crack resistant; and meanwhile, the powdering phenomenon of the lightweight concrete is improved, and the use performance of the lightweight concrete is greatly improved.
本发明提供一种用于轻质混凝土，属于混凝土技术领域，其中轻质混凝土板材用添加剂包括如下质量百分比的原料：聚丙烯纤维20～30%、乳胶粉20～30%、减水剂20～30%、膨化剂20～30%、矿粉20～30%，还发明还包括混凝土及混凝土板材的制备方法，本发明具有抗压强度、抗裂强度高，同时又改善了轻质混凝土的粉画现象，大大提高了轻质混凝土的使用性能。
