Cement paste as well as preparation method and application thereof
The invention provides cement paste as well as a preparation method and application thereof, and relates to the technical field of grouting materials. The cement paste provided by the invention is prepared from the following raw materials in parts by mass: 50-80 parts of cement, 0-25 parts of fly ash, 0-15 parts of silica fume, 0-1 part of a water reducing agent, 0-1 part of a stabilizer, 1-2 parts of an early strength agent, 0.1-1 part of a defoaming agent, 0-8 parts of an expanding agent and 15-25 parts of water. The cement, the fly ash and the silica fume are taken as main materials, the water reducing agent, the stabilizer, the early strength agent, the defoaming agent and the expanding agent are taken as auxiliary materials, and scientific compounding is adopted, so that the obtained cement paste has excellent flowability, low bleeding rate and outstanding foam inhibition performance, and meanwhile, the cement paste has the characteristics of rapid development of early-stage (7d) fracture resistance and compressive strength, high strength and the like. In the later stage (28d), the fracture resistance and the compressive strength are continuously increased, the shrinkage rate is low, and the grouting compactness is good.
本发明提供了一种水泥净浆料及其制备方法和应用，涉及灌浆料技术领域。本发明提供的水泥净浆料，按质量份数计，包括以下制备原料：水泥50～80份、粉煤灰0～25份、硅灰0～15份、减水剂0～1份、稳定剂0～1份、早强剂1～2份、消泡剂0.1～1份、膨胀剂0～8份和水15～25份。本发明以水泥、粉煤灰和硅灰作为主料，以减水剂、稳定剂、早强剂、消泡剂和膨胀剂作为辅料，采用科学复配，得到的水泥净浆料具有优异的流动性，且该水泥净浆料泌水率低和抑泡性能突出，同时具有早期(7d)抗折、抗压强度发展迅速，后期(28d)抗折、抗压强度持续增长、收缩率低和灌浆的密实性好的特点。
