Decoration-free colored C30 self-compacting bare concrete and preparation method thereof
The invention discloses decoration-free colored C30 self-compacting bare concrete and a preparation method thereof, and the concrete is prepared from the following components in parts by mass: 150 to 170 parts of water, 230 to 260 parts of cement, 40 to 70 parts of fly ash, 30 to 50 parts of mineral powder, 920 to 990 parts of coarse aggregate, 850 to 950 parts of fine aggregate, 5 to 15 parts of inorganic pigment, 4 to 8 parts of water reducing agent and 0.01 to 0.03 part of air entraining agent. The C30 decoration-free colored bare concrete prepared according to the proportion disclosed by the invention has the advantages that the volume weight is 2450-2400Kg/m < 3 >, the gas content is 1-2.5%, the compressive strength is greater than or equal to 30MPa, the appearance is flat, the color is uniform, various appearance patterns can be formed according to patterns on the surface of a mold, and the mold can be automatically filled and compacted.
本发明公开了一种免装饰彩色C30自密实清水混凝土及其制备方法，混凝土按质量份数计，包括以下组分：水150‑170份、水泥230‑260份、粉煤灰40‑70份、矿粉30‑50份、粗骨料920‑990份、细骨料850‑950份、无机颜料5‑15份、减水剂4‑8份，引气剂0.01‑0.03份。按照本发明中配比制备的C30免装饰彩色清水混凝土容重2450‑2400Kg/m3，含气量1‑2.5％，抗压强度≥30MPa，外观平整，颜色均匀，可根据摸具表面图案成型各种外观图案，可自动填充密实模具。
