Preparation method of dolomite composite material
The invention discloses a dolomite composite material preparation method, which comprises: uniformly mixing modified dolomite powder, dehydrated phosphogypsum, a polyether-siloxane copolymer, long-chain polyunsaturated fatty acid, polypropylene glycol glycidyl ether, nano-silica and long-chain fatty acid to obtain the target product dolomite composite material. The dolomite composite material disclosed by the invention can be used as an external additive of concrete, has the functions of crack resistance, permeability resistance and shrinkage compensation, effectively improves the compactness of the concrete and compensates the shrinkage of the concrete, so that the permeability resistance and the crack resistance are improved.
本发明公开了一种白云石复合材料的制备方法，包括以下步骤：将改性白云石粉、脱水磷石膏、聚醚‑硅氧烷共聚物、长链多不饱和脂肪酸、聚丙二醇缩水甘油醚、纳米二氧化硅、长链脂肪酸混合均匀，即可得目标产物白云石复合材料。本发明的白云石复合材料可作为混凝土的一种外添加剂，其具有抗裂、抗渗、补偿收缩的功能，有效提高混凝土密实性，补偿混凝土收缩，从而提高抗渗抗裂性能。
