The invention relates to the field of concrete, and particularly discloses reinforced recycled concrete and a production process thereof. The reinforced recycled concrete is mainly prepared from the following raw materials in percentage by mass: 50-70% of modified aggregate, 15-20% of cement and 8-12% of water, wherein the modified aggregate is prepared by soaking recycled aggregate in nano-modification liquid for 24-72 hours. The production process comprises the following steps: performing impurity removal, crushing and screening on waste concrete and waste bricks to obtain recycled coarse aggregate and recycled fine aggregate, and soaking the recycled coarse aggregate and the recycled fine aggregate in nano-modification liquid respectively to obtain modified coarse aggregate and modified fine aggregate; and weighing the raw materials in proportion, and uniformly mixing the raw materials to obtain the reinforced recycled concrete. The reinforced recycled concrete has enough strength and durability, aggregate in the raw materials is selected from waste concrete and waste bricks, and the utilization rate of building waste is increased.
本申请涉及混凝土领域，具体公开了一种强化再生混凝土及其生产工艺。强化再生混凝土，按质量分数计，原料主要包括改性骨料50‑70%、水泥15‑20%和水8‑12%，所述改性骨料由再生骨料置于纳米改性液中浸泡24‑72h制得；其生产工艺为：将废混凝土和废砖块进行除杂、破碎和筛分，得到再生粗骨料和再生细骨料，再分别浸入纳米改性液中浸泡，得到改性粗骨料和改性细骨料；按比例称取各原料，混合均匀后得到强化再生混凝土。本申请的强化再生混凝土具有足够的强度和耐久性能，原料中的骨料均选用废混凝土和废砖块，提高了建筑废弃物的利用率。
