Anti-deformation concrete and preparation method thereof

The invention discloses anti-deformation concrete and a preparation method thereof. A water reducing agent is enhanced by introducing octahedral cage-type polysilsesquioxane, the number of adsorptiongroups is increased, adsorption of polycarboxylic acid on the surface of a mineral admixture is enhanced, and the adaptability and the dispersing performance of the polycarboxylic acid water reducingagent are improved. Meanwhile, the anti-deformation capacity of the concrete is improved by using a cementing material optimizing agent, the compressive strength of cement mortar is improved, and thewater reducing effect of material components is optimized. The concrete which is excellent in performance, short in mixing time, good in initial fluidity and high in anti-deformation capacity is prepared. 本发明公开了一种抗变形混凝土及其制备方法，通过引入八面笼型聚倍半硅氧烷对减水剂进行增强，增加了吸附基团数量，增强了聚羧酸在矿物掺合料表面的吸附，提高聚羧酸减水剂的适应性和分散性能。同时，使用胶凝材料优化剂提高混凝土的抗变形能力，增加水泥砂浆的抗压强度，优化材料组分的减水效果。制备出一款性能优异，拌合时间短，初始流动性良好，抗变形能力高的混凝土。
