Concrete recycled aggregate and preparation process thereof
The invention discloses a concrete recycled aggregate and a preparation process thereof. The concrete recycled aggregate comprises, by weight, 40-50% of waste concrete powder, 3-5% of mineral powder, 2-3% of cellulose, 5-10% of a water reducing agent, 1-1.5% of a viscosity modifier, 2-6% of a retarder, 10-15% of cement, 1-2% of talcum powder, 0.5-1.5% of pearl powder, 1.5-3% of bentonite, latex powder and 30-45% of water, and is prepared by mixing and stirring through processing equipment. The processing equipment comprises a mixing box, supporting legs are arranged on the outer wall of the bottom of the mixing box, and a feeding port and a controller are arranged on the outer walls of the two sides of the top of the mixing box correspondingly. The mineral powder, the cellulose, the water reducing agent, the viscosity modifier, the retarder, the cement, the talcum powder, the pearl powder and the bentonite are added into the waste concrete powder, and are mixed and stirred with water, all the raw materials are fully mixed through processing equipment, and the mixture is granulated through granulating equipment to obtain concrete recycled aggregate particles which are high in strength and not prone to generating cracks and gaps can be obtained, so the product quality is greatly improved.
本发明公开了一种混凝土再生骨料及其制备工艺，包括由以下组分按重量百分比组成：废弃混凝土碎末40％‑50％、矿粉3％‑5％、纤维素2％‑3％、减水剂5％‑10％、粘度调节剂1％‑1.5％、缓凝剂2％‑6％、水泥10％‑15％、滑石粉1％‑2％、珍珠粉0.5％‑1.5％、膨润土1.5％‑3％、乳胶粉和水30％‑45％通过加工设备混合搅拌所得，所述加工设备包括混合箱，所述混合箱底部外壁设有支脚，且混合箱顶部两侧外壁分别设有投料口和控制器。本发明通过向废弃混凝土碎末内添加矿粉、纤维素、减水剂、粘度调节剂、缓凝剂、水泥、滑石粉、珍珠粉和膨润土，通过与水混合搅拌，通过加工设备使各个原料充分混合，在通过制粒设备将其制粒，即可得到高强度、不易产生裂缝空隙的混凝土再生骨料颗粒，从而大大提升产品质量。
