Bare concrete produced from construction waste recycled aggregate
The invention relates to the field of concrete, and particularly discloses bare concrete produced from construction waste recycled aggregate. The bare concrete is prepared from the following raw materials by weight: 360-420 parts of cement, 42-65 parts of fly ash, 15-28 parts of mineral powder, 710-730 parts of river sand, 1100-1200 parts of modified recycled coarse aggregate, 5.6-7.8 parts of an additive, 5-8.6 parts of composite fiber, and 150-180 parts of water. The modified recycled coarse aggregate is prepared by adopting the following method of pretreating waste concrete to obtain recycled coarse aggregate, weighing modified acrylate emulsion, modified diatomite and chitosan membrane liquid, sequentially spraying on the surface of the recycled coarse aggregate, and drying to obtain the modified recycled coarse aggregate. The method has the effect of preventing acid radical ions from entering the internal structure of the concrete to influence the strength of the bare concrete.
本申请涉及混凝土领域，具体公开了一种建筑垃圾再生骨料生产的清水混凝土，所述清水混凝土由包含以下重量份的原料制成：水泥360‑420份、粉煤灰42‑65份、矿粉15‑28份、河砂710‑730份、改性再生粗骨料1100‑1200份、外加剂5.6‑7.8份、复合纤维5‑8.6份、水150‑180份；改性再生粗骨料采用如下方法制备而成：取废旧混凝土经预处理后制得再生粗骨料，称取改性丙烯酸酯乳液、改性硅藻土、壳聚糖膜液依次喷涂在再生粗骨料表面经烘干后，制得改性再生粗骨料；具有避免酸根离子进入混凝土内部结构中，影响清水混凝土强度的效果。
