High-strength lightweight concrete
The invention relates to the technical field of concrete. The invention aims to provide high-strength lightweight concrete. Key points of the technical scheme are as follows: the high-strength lightweight concrete is prepared from 500 to 650 parts of a lightweight aggregate, 150 to 220 parts of a recycled aggregate, 80 to 120 parts of a natural aggregate, 400 to 650 parts of fine sand, 220 to 300parts of cement, 50 to 70 parts of fly ash, 40 to 60 parts of mineral powder, 0.5 to 1.5 parts of an air entraining agent, 2 to 3 parts of a foaming agent, 1.5 to 2.5 parts of a water reducing agent,165 to 180 parts of water and reinforced fibers with a volume percentage of 0.1-0.3%. The lightweight aggregate is ceramsite with the particle size ranging from 15 mm to 22 mm, and the recycled aggregate comprises a recycled coarse aggregate and a recycled fine aggregate according to the weight ratio of 1: (0.8-1.5). The high-strength lightweight concrete has the advantages of effective utilization of recycled concrete raw materials, high strength, energy saving and environmental protection.
本发明涉及混凝土技术领域，旨在提供一种高强轻质混凝土，其技术方案要点是：包括以下重量份组分：轻骨料500‑650份、再生骨料150‑220份、天然骨料80‑120份、细砂400‑650份、水泥220‑300份、粉煤灰50‑70份、矿粉40‑60、引气剂0.5‑1.5份、发泡剂2‑3份、减水剂1.5‑2.5份、水165‑180份，还包括体积百分比为0.1‑0.3%的增强纤维，轻骨料为粒径范围是15‑22mm的陶粒，再生骨料包括重量比为1:(0.8‑1.5)的再生粗骨料和再生细骨料。本发明具有可有效利用再生混凝土原料，强度高，节能环保的优点。
