Pumpable light thermal insulation concrete and preparation method thereof
The invention relates to the field of concrete preparation, and particularly discloses pumpable light thermal insulation concrete and a preparation method thereof. According to the pumpable light thermal insulation concrete, polystyrene foam particles are modified, and different layers of mixed powder and reinforced fibers are bonded on the polystyrene foam particles, so that the fireproof grade of the light thermal insulation concrete can be improved, the heat conductivity coefficient of the concrete is reduced, the fireproof grade reaches grade A, the compressive strength is 5.33 MPa or above, and the pumpable light thermal insulation concrete has good thermal insulation performance. And the heat conductivity coefficient is below 0.062 W/(m.K). The preparation method comprises the following steps: carrying out dry mixing on the cement, the fly ash, the mineral powder, the gelling agent, the modified polystyrene foam particles and the coarse aggregate in a mixer, fully mixing, and adding water. The method is simple and easy to control, raw materials are easy to obtain, and batch production is easy to achieve.
本申请涉及混凝土制备的领域，具体公开了一种可泵送轻质保温混凝土及其制备方法。一种可泵送轻质保温混凝土通过对聚苯乙烯泡沫颗粒的改性，在聚苯乙烯泡沫颗粒上粘结不同层数的混合粉末及增强纤维，能够提高轻质保温混凝土的防火等级同时降低混凝土的导热系数，防火等级达到A级，抗压强度在5.33MPa以上，导热系数0.062 W/(m·K)以下。其制备方法为：将水泥、粉煤灰、矿粉、胶凝剂、改性聚苯乙烯泡沫颗粒、粗骨料在搅拌机中进行干拌，充分混合后加入水。本申请的方法较为简单，易于控制，且原料易于获取，易实现批量化生产。
