摘要 采用整体着色方法,在普通混凝土中加入适量的稻壳灰,可将原本灰白色的混凝土变成不同层次的灰色混凝土,以减少大量的二次装修。随着稻壳灰掺量的增加,混凝土灰色不断加深,同时,新拌混凝土的流动性略有降低,黏聚性变得越来越好,不泌水;在混凝土中加入适量的稻壳灰,可以提高硬化混凝土的抗压强度,增强混凝土的抗冻性能和抗渗性能。 By the integral tinting methods, addition suitable amount ofrice husk ash (RHA) into the ordinary concrete to deepen its color,will origi- nally gray concrete become different hierarchy gray, and can reduce a lot of the second decorating.With the increase of RHA, the concrete's color deepening, at the same time, the new mix concrete liquidity lowered, cohesiveness increased, and the strength of concrete increased, the anti-freeze and anti-permeability level increased slightly.
