Recycled fair-faced concrete prepared from peanut shell powder
The invention discloses recycled fair-faced concrete prepared from peanut shell powder. The recycled fair-faced concrete is prepared from the following components in parts by weight: 340-425 parts ofwhite cement, 15-18 parts of peanut shell powder, 10-60 parts of iron oxide powder, 740-780 parts of modified recycled fine aggregate, 900-950 parts of modified recycled coarse aggregate, 2-6 parts ofwater reducing agent, 0.2-0.8 part of defoaming agent, 1-2 parts of air entraining agent and 150-160 parts of water, wherein the water binder ratio is 0.35-0.45. The defoamer and the air entraining agent are utilized to eliminate harmful bubbles and generate tiny bubbles playing roles in lubricating and stabilizing component distribution, and the content of the iron oxide powder is adjusted to change the color of the concrete, thereby preparing the fair-faced concrete. The aggregates are all recycled aggregates so that the concrete has the characteristic of environmental protection.
本发明公开了一种花生壳粉制备的再生清水混凝土，按重量份计，包括以下组分，白水泥340‑425份，花生壳粉15‑18份，氧化铁粉末10‑60份，改性再生细骨料740‑780份，改性再生粗骨料900‑950份，减水剂2‑6份，消泡剂0.2‑0.8份，引气剂1‑2份，水150‑160份，水胶比为0.35‑0.45。本发明利用消泡剂和引气剂，消除有害气泡，产生起润滑和稳定组分分布作用的微小气泡，调节氧化铁粉末的含量来改变混凝土颜色，制备清水混凝土；骨料全部使用再生骨料，具有绿色环保的特点。
