Recycled concrete doped with construction waste and processing technology thereof
The invention provides recycled concrete doped with construction waste and a processing technology of the recycled concrete. The recycled concrete based on doped construction waste is prepared from 15%-20% of cement, 30%-40% of recycled coarse aggregate, 25%-35% of recycled fine aggregate, 10%-20% of natural river sand, water with the water-cement ratio being about 0.45-0.60 and an additive, S1, the construction waste is screened and classified, unsuitable materials such as metal, wood and plastic are removed, the construction waste is crushed, then pretreatment is conducted, and the recycled concrete is obtained; s2, detecting the physical and chemical properties of the recycled aggregate, detecting the quality of cement and sand, and ensuring that no harmful substances exist. The construction waste is crushed, point positions which are not firmly connected are crushed, strength reduction caused by crushing in the using process is avoided, the outer surface of the construction waste is coated, increase of the water absorption capacity is reduced, the bonding performance is improved, and the water content is adjusted through small-scale testing.
本发明提供一种掺杂建筑垃圾的再生混凝土及其加工工艺。该基于一种掺杂建筑垃圾的再生混凝土，包括，水泥：15％‑20％、再生粗骨料：30％‑40％、再生细骨料：25‑35％、天然河砂：10‑20％、水：水灰比约为0.45‑0.60、添加剂，S1、对建筑垃圾进行筛选和分类，剔除金属、木材和塑料不适宜的材料，进行建筑垃圾破碎处理，再进行预处理，清洗骨料以去除附着的灰尘和杂物，S2、对再生骨料的物理和化学性能进行检测，检测水泥和砂的质量，确保无有害物质。通过实现对建筑垃圾进行破碎，将连接不牢固的点位进行破碎，避免在使用的过程中由于破碎造成强度下降，并通过对建筑垃圾的外表面进行涂层，降低吸水量的增加，以及增加黏结性能，并通过小规模的测试，调整含水量。
