The invention discloses white fair-faced concrete for a prefabricated part and a preparation method of the white fair-faced concrete. Each cubic meter of the concrete comprises the following components by weight: 320-400kg of cement, 50-190kg of an admixture, 820-1010kg of coarse aggregate, 630-980kg of fine aggregate, 0-15kg of a homogeneity regulator, 5-16kg of a water reducing agent, 145-170kg of water and 0-35kg of titanium dioxide, and the total volume weight of the concrete is 2320-2430kg/m<3>. The C35-C80 grade white fair-faced concrete with high whiteness requirements such as light white and creamy white can be obtained, the requirements for high early strength and rapid demolding of components are met, the concrete is environmentally friendly, low in cost and flexible and adjustable in flowability, 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 concrete can be applied to fabricated buildings or wind power concrete tower components, and has practical production operability and popularization value.
本发明公开了一种预制构件用白色清水饰面混凝土及其配制方法，每立方混凝土包括以下重量组分：水泥320～400kg，掺合料50～190kg，粗骨料820～1010kg，细骨料630～980kg，匀质性调节剂0～15kg，减水剂5～16kg，水145～170kg，钛白粉0～35kg，混凝土总容重为2320～2430kg/m3。本发明可得C35～C80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，无需改造或添加生产设备，可应用于装配式建筑或风电混凝土塔筒构件，具有实际生产可操作性和推广价值。
