C30 carbon fiber broken brick recycled concrete and preparation method thereof
The invention discloses C30 carbon fiber broken brick recycled concrete. The concrete is prepared from the following raw materials in parts by weight: 380-400 parts of cement, 200-220 parts of water,650-670 parts of river sand, 610-630 parts of broken bricks, 7-9 parts of carbon fibers, 80-120 parts of fly ash, 40-60 parts of silica fume, 6-8 parts of a water reducing agent, 10-12 parts of an exciting agent, 0.9-1.2 parts of a dispersing agent and 0.6-0.7 part of a defoaming agent. The invention also provides a preparation method thereof. The materials available in the market are utilized inthe concrete; an improved concrete stirring process is adopted, and carbon fibers, silica fume, fly ash, hydroxypropyl methyl cellulose, chemical additives and the like are doped, so that the defectsof low strength, high brittleness, easiness in cracking and the like of broken brick recycled concrete are overcome, and the carbon fiber concrete with excellent workability, relatively high ductilityand a C30 strength grade is prepared.
本发明公开了一种C30碳纤维碎砖再生混凝土，所述混凝土由包括如下重量份的原料制成：水泥380‑400份、水200‑220份、河砂650‑670份、碎砖610‑630份、碳纤维7‑9份、粉煤灰80‑120份、硅灰40‑60份、减水剂6‑8份、激发剂10‑12份、分散剂0.9‑1.2份、消泡剂0.6‑0.7份；并提供了其制备方法。该混凝土利用市场易得材料，采用改进的混凝土搅拌工艺，通过掺加碳纤维、硅灰、粉煤灰、羟丙基甲基纤维素、化学外加剂等，克服碎砖再生混凝土强度低、脆性大、易开裂等缺点，以制备具有优良和易性、较高延性的C30强度等级的碳纤维混凝土。
