Gamma-C2S phosphogypsum lightweight aggregate ultra-high performance concrete and preparation method thereof
The invention discloses gamma-C2S ardealite lightweight aggregate ultra-high performance concrete which comprises the following components: 600-700 kg/m < 3 > of cement, 100-150 kg/m < 3 > of fly ash, 150-200 kg/m < 3 > of silica fume, 200-400 kg/m < 3 > of modified gamma-C2S ardealite unfired aggregate, 80-100 kg/m < 3 > of copper-plated steel fiber, 300-700 kg/m < 3 > of medium sand, 40-92 kg/m < 3 > of floating beads, 260-608 kg/m < 3 > of fine sand, 8-15 kg/m < 3 > of a water reducing agent, 0.5-2 kg/m < 3 > of a defoaming agent and 150-190 kg/m < 3 > of water. The ultra-high performance concrete is small in density and low in self-shrinkage, can give consideration to excellent working performance, mechanical performance and the like, is beneficial to promotion of application of industrial solid waste light aggregate in UHPC, has remarkable environmental and economic benefits and is suitable for popularization and application.
本发明公开了一种γ‑C2S磷石膏轻集料超高性能混凝土，各组分及其含量包括：水泥600‑700kg/m3，粉煤灰100‑150kg/m3，硅灰150‑200kg/m3，改性γ‑C2S磷石膏免烧集料200‑400kg/m3，铜镀钢纤维80‑100kg/m3，中砂300‑700kg/m3，漂珠40‑92kg/m3，细砂260‑608kg/m3，减水剂8‑15kg/m3，消泡剂0.5‑2kg/m3，水150‑190kg/m3。所述超高性能混凝土的密度小、自收缩低，并可兼顾优异的工作性能和力学性能等，有利于推进工业固废轻集料在UHPC中的应用，具有显著的环境和经济效益，适合推广应用。
