Self-compacting quick-setting dry-mixed mortar and preparation method thereof
The invention discloses self-compacting quick-setting dry-mixed mortar and a preparation method thereof, and the dry-mixed mortar is prepared by mixing the following components in parts by weight: 100 parts of cement, 200-400 parts of quartz sand, 1-2 parts of a water reducing agent, 0.5-1.0 part of a defoaming agent, 1-3 parts of redispersible latex powder, 1-5 parts of a viscosity adjusting component, 0.1-0.3 part of PP fiber, 15-30 parts of a boric sludge admixture and 1-5 parts of an accelerator, the preparation method of the self-compacting quick-setting dry-mixed mortar comprises the following steps: mixing by adopting a high-speed mixer in a factory, transporting by adopting a bulk vehicle or a bagged vehicle, weighing the dry-mixed mortar, the coarse aggregate and the water according to the proportion on a construction site, and uniformly stirring to obtain the self-compacting quick-setting dry-mixed mortar. The prepared dry-mixed mortar can greatly reduce the sensitivity to quality fluctuation of raw materials, remarkably reduce the shrinkage rate of concrete and improve the bonding performance of concrete or a cement base material and an original interface, and is suitable for the fields of bridges, roads, civil buildings and repair and reinforcement.
本发明公开了一种自密实速凝干粉砂浆及其制备方法，所述干粉砂浆由以下组分按重量份数计混合制成：水泥100份、石英砂200～400份、减水剂1～2份、消泡剂0.5～1.0份、可再分散乳胶粉1～3份、黏度调节组分1～5份、PP纤维0.1～0.3份、硼泥掺合料15～30份、速凝剂1～5份，所述自密实速凝干粉砂浆的制备方法为在工厂采用高速混料机混合而成，采用散装车或袋装汽车运输，在施工现场按比例称取干粉砂浆、粗骨料和水后搅拌均匀即可。本发明制备的干粉砂浆可大幅度降低对原材料品质波动的敏感性，显著降低混凝土的收缩率，提高混凝土或水泥基材与原有界面粘结性能，适用于桥梁、道路、民用建筑及修补加固领域。
