Preparation method of pavement patching mortar layer structure
The invention relates to the technical field of repairing mortar, and discloses a preparation method of a pavement repairing mortar layer structure which comprises the following raw materials in parts by weight: cement, sand, fly ash, mineral powder, water, sodium aluminate, sodium carbonate, quick lime, quartz powder, caustic soda, polyacrylate emulsion, a dispersing agent and a thixotropic agent. According to the preparation method of the pavement repairing mortar layer structure, hydration hardening of cement is accelerated through sodium aluminate, sodium carbonate and quick lime, enough strength is formed in a very short time, the thickening waterproof performance, the bonding performance, the crack resistance, the freezing resistance, the seepage resistance, the corrosion resistance, the chloride ion permeation resistance, the aging resistance and the corrosion resistance of mortar can be improved through the arrangement of polyacrylate emulsion, and the pavement repairing mortar layer structure is suitable for being used for pavement repairing. By adding the fly ash, gaps between the mortar can be reduced, the strength and the waterproof performance of the mortar can be improved, and by adding the mineral powder, the compactness of the mortar can be improved, and the impermeability and the erosion resistance can be improved.
本发明涉及修补砂浆技术领域，且公开了一种路面修补砂浆层结构的制备方法，包括以下重量份数配比的原料：水泥、砂子、粉煤灰、矿粉、水、铝酸钠、碳酸钠、生石灰、石英粉、烧碱、聚丙烯酸酯乳液、分散剂和触变剂。该路面修补砂浆层结构的制备方法，通过铝酸钠、碳酸钠和生石灰的加速水泥的水化硬化，在很短的时间内形成足够的强度，通过的聚丙烯酸酯乳液的设置，能够提高砂浆的增稠防水、粘结、抗裂、抗冻、防渗、防腐、抗氯离子渗透、耐老化和耐蚀性能，通过粉煤灰的添加，能够减小砂浆之间的缝隙，提高砂浆的强度和防水性能，通过矿粉的添加，能够提高砂浆的密实度，提高抗渗和抗侵蚀能力。
