Concrete containing waste brick powder and fly ash
The invention provides a concrete containing waste brick powder and fly ash. The concrete is prepared from cement, natural coarse aggregate, waste brick aggregate, fly ash, an activator and water according to a weight ratio of 1: (1.20-1.50): (0.80-1.20): (0.10-0.80): (0.20-0.8): (0.40-1.50), and the activator is from waste brick powder. The concrete has high strength, and the cost is not obviously increased. The waste brick powder and the fly ash are combined to replace part of cement, so that the mechanical property and the surface density of the concrete are remarkably improved, and the production cost is reduced.
本发明提供了一种包含废砖粉和粉煤灰的混凝土，其由水泥、天然粗骨料、废砖骨料、粉煤灰、激发剂和水按重量比1:(1.20～1.50):(0.80～1.20):(0.10～0.80):(0.20～0.8):(0.40～1.50)制备而成，所述激发剂来自废砖粉。该混凝土具有高强度并成本不明显提高。利用废砖粉和粉煤灰组合取代部分水泥,混凝土的力学性能和表面密度能得到显著改善，并且生产成本得到改善。
