一种轻集料高性能混凝土及其制备方法
摘要：
本发明公开了一种轻集料高性能混凝土及其制备方法，包括如下原料：水泥180～310份、陶粒580～650份、陶砂420～500份、建筑垃圾再生砂0～80份、粉煤灰100～130份、矿粉100～210份、水130～160份、减水剂4.5～6.5份、增强改性材料1～1.5份及抗离析材料0.45～0.60份。优点为该轻集料混凝土不仅具有容重轻(1450～1550kg/m3)、28天强度高(40～50MPa)、且抗离析可泵送，即坍落度190～250mm，扩展度400～550mm及骨料不上浮；同时，其制法简单，可操作性强，成本低。
摘要（英）：

The invention discloses a lightweight aggregate high-performance concrete and a preparation method thereof. The lightweight aggregate high-performance concrete contains the following raw materials: 180-310 parts of cement, 580-650 parts of ceramsite, 420-500 parts of pottery sand, 0-80 parts of sand regenerated from construction waste, 100-130 parts of coal ash, 100-210 parts of mineral powder, 130-160 parts of water, 4.5-6.5 parts of water reducer, 1-1.5 parts of enhanced modified material and 0.45-0.60 part of anti-separation material. The lightweight aggregate high-performance concrete has the advantages of light unit weight (1450-1550kg/m3), high 28-day strength (40-50MPa), separation resistance, capability of being pumped, slump of 190-250mm, divergence of 400-550mm, no aggregate floating, simple preparation method, high operability and low cost.
