Self-compacting white fair-faced concrete
The invention discloses a self-compacting white bare concrete. Each cubic meter of the self-compacting white bare concrete is composed of the following components: 390-410 kg of white cement, 780-850 kg of sand, 880-920 kg of stone, 5-10 kg of titanium dioxide, 8-9 kg of a water reducing agent and water, and the water-binder ratio of the self-compacting white bare concrete is 0.38-0.45. The fineness modulus of the sand is 2.8, and the silt content is 1t; the chloride ion content is 1t; 0.06% by weight; the stones are graded stones with the particle size of 5-15mm and the bulk density of gt; the crushing value is smaller than or equal to 18%, the water absorption rate is smaller than or equal to 2%, the mud content is smaller than or equal to 0.5%, and the acicular and flaky particle content of stones is 1t; 8%. The method solves the problem that the appearance quality after demolding is affected by blind vibration when traditional bare concrete is adopted in a special-shaped curved surface bare concrete project.
本发明公开了一种自密实白色清水混凝土，每立方米的自密实白色清水混凝土由以下组分构成：390～410kg的白水泥、780～850kg的砂、880～920kg的石子、5～10kg的钛白粉、8～9kg的减水剂和水，自密实白色清水混凝土的水胶比0.38～0.45；砂的细度模数为2.8、含泥量<2％、氯离子含量<0.06％；石子为粒度为5～15mm的级配石子、堆积密度>1350kg/m3、压碎值≤18％、吸水率≤2％、含泥量≤0.5％，石子的针状及片状颗粒含量<8％。本发明解决了异形曲面清水混凝土工程采用传统的清水混凝土和盲振影响脱模后的外观质量的问题。
