The invention relates to the field of concrete, and particularly discloses regenerated dry-mixed composite lightweight aggregate concrete and a preparation method thereof. The regenerated dry-mixed composite light aggregate concrete is prepared from the following raw materials in parts by weight: 200-300 parts of cement, 32-48 parts of admixture powder, 45-70 parts of active regenerated micro powder, 40-60 parts of recycled fine aggregate, 35-70 parts of dry sand, 60-90 parts of hydrophobic polyurethane particles, 20-30 parts of fibers, 5-8 parts of a waterproof agent, 7-10 parts of a flame retardant, 6-9 parts of a water reducing agent, 3-5 parts of an early strength agent, 1-3 parts of redispersible latex powder and 80-100 parts of water. The preparation method comprises the following steps: uniformly mixing the hydrophobic polyurethane particles and the flame retardant with part of cement and water, and uniformly mixing with the rest raw materials. The regenerated dry-mixed composite light aggregate concrete can be used as heat-insulating light aggregate concrete, and has the advantage of relatively high strength.
本申请涉及混凝土的领域，具体公开了一种再生干拌复合轻集料混凝土及其制备方法。一种再生干拌复合轻集料混凝土，其由包括以下重量份的原料配制而成：水泥200‑300份、掺和粉料32‑48份、活性再生微粉45‑70份，再生细骨料40‑60份、干沙35‑70份、憎水聚氨酯颗粒60‑90份、纤维20‑30份、防水剂5‑8份、阻燃剂7‑10份、减水剂6‑9份、早强剂3‑5份、可再分散性乳胶粉1‑3份、水80‑100份；其制备方法为：现将憎水聚氨酯颗粒与阻燃剂跟部分水泥与水混合均匀后，再与剩余原料混合均匀。本申请的再生干拌复合轻集料混凝土可用做保温轻集料混凝土，其具有强度相对较高的优点。
