White fair-faced concrete for assembly type component and preparation method of white fair-faced concrete
The invention discloses white fair-faced concrete for an assembly type component and a preparation method of the white fair-faced concrete. The concrete per cubic meter comprises the following components by weight: 300 to 370 kg of cement, 50 to 130 kg of an admixture, 820 to 950 kg of coarse aggregate, 730 to 980 kg of fine aggregate, 0.057 to 15 kg of a homogeneity conditioning agent, 5 to 13 kg of a water reducing agent, 150 to 170 kg of water and 0 to 32 kg of titanium dioxide. The white fair-faced concrete with the high whiteness requirement of C35-C50 grade light white and creamy white or above can be obtained, the requirements of high early strength and rapid demolding of components are met, the concrete is environmentally friendly, low in cost and flexible and adjustable in fluidity, the concrete surface is flat, fine and smooth, the color is uniform and basically consistent, secondary decoration is not needed, production equipment does not need to be transformed or added, and the production cost is reduced. The method has practical production operability and popularization value.
本发明公开了一种装配式构件用白色清水饰面混凝土及配制方法。每立方混凝土包括以下重量组分：水泥300～370kg，掺合料50～130kg，粗骨料820～950kg，细骨料730～980kg，匀质性调节剂0.057～15kg，减水剂5～13kg，水150～170kg，钛白粉0～32kg。本发明可得C35～C50等级浅白色、米白色以上高白度要求的白色清水混凝土，满足构件高早强和快速脱模要求，绿色环保，成本较低，流动性灵活可调，混凝土表面平整且细腻光滑、色泽均匀颜色基本一致、不需要二次装饰，且无需改造或添加生产设备，更具有实际生产可操作性和推广价值。
