Recycled concrete and production process thereof
The invention relates to construction waste disposal and recycling, and particularly discloses recycled concrete and a production process thereof, the production process is simple and convenient, and the recycled concrete comprises the following raw materials in parts by mass: 400-500 parts of recycled aggregate; 500 to 600 parts of natural aggregate; 300 to 360 parts of cement; 520 to 590 parts of sand; 120 to 140 parts of water; the recycled aggregate is obtained by permeating and doping polyaluminum chloride into the surfaces of the old concrete fragments, and 6.5-8.5 kg of polyaluminum chloride is doped into each ton of the old concrete fragments, so that after the recycled aggregate is permeated and doped with the polyaluminum chloride, the recycled aggregate and other raw materials have a synergistic effect in the production process of the recycled concrete, and the recycled concrete has the advantages of high strength, high strength and high durability. The strength and binding property of the recycled aggregate are improved during concrete preparation, and finally the strength-enhanced recycled concrete is obtained.
本申请涉及建筑垃圾处置与资源化，具体公开了一种再生混凝土及其生产工艺，生产工艺简单便利，其再生混凝土包括以下质量份数的原料再生骨料400~500份；天然骨料500~600份；水泥300~360份；砂520~590份；水120~140份；再生骨料为旧混凝土碎片表面渗透掺入聚合氯化铝得到，每吨旧混凝土碎片内掺入聚合氯化铝量为6.5~8.5kg，由此综上，本申请的再生骨料经过渗透掺入聚合氯化铝后，在再生混凝土生产过程中与其他原料发生协同增效效果，使得再生骨料在混凝土制备时强度和结合性得到提高，最终获得一种强度增强的再生混凝土。
