Ecological ultra-high performance concrete and application thereof
The invention provides ecological ultra-high performance concrete and application thereof. The ecological ultra-high performance concrete comprises cement, silica fume, fly ash, lead-zinc tailings, sand, water, a water reducing agent and steel fibers, and the mass ratio of the lead-zinc tailings to the ecological ultra-high performance concrete is less than 40%. The ecological ultra-high performance concrete is beneficial to solving the accumulation problem of lead-zinc tailings; and the material cost and the energy consumption are reduced, the total cost in the life cycle is far lower than that of a common concrete bridge and the environmental cost is obviously lower than that of the ultra-high performance concrete bridge and the common concrete bridge when the ecological ultra-high performance concrete is used in a simply supported bridge, the sustainable development strategy is met, and the ecological ultra-high performance concrete has a good application prospect in future bridge construction.
本发明提供了一种生态型超高性能混凝土及其应用，所述生态型超高性能混凝土包括水泥、硅灰、粉煤灰、铅锌尾矿、砂、水、减水剂和钢纤维，所述铅锌尾矿占所述生态型超高性能混凝土的质量比例小于40%。本发明的生态型超高性能混凝土有利于解决铅锌尾矿的堆积问题，并且降低了材料成本与能耗，将其用于简支桥梁中，在生命周期中的总成本远低于普通混凝土桥梁，其环境成本也要明显低于超高性能混凝土桥梁和普通混凝土桥梁，符合可持续发展战略，在未来的桥梁建设中具有良好的应用前景。
