Alkali-activated concrete prepared from cement wastewater
The invention discloses alkali-activated concrete prepared from cement wastewater. The alkali-activated concrete is prepared from the following raw materials: cement wastewater, an alkali activator and slag. The cement wastewater is used as a mixing water source of the alkali-activated concrete to prepare the alkali-activated concrete; sodium, calcium and other ions in the cement wastewater are used for assisting in exciting a cementing material to promote formation of a reinforced cementitious body, waste is turned into wealth, harm is turned into treasure, the treatment and utilization process of the cement wastewater is greatly simplified, economic, safe and environmental burdens of building enterprises are reduced, the economic value of the wastewater is improved to the level of common tap water in cities, and the national environmental protection policy requirements are met. The application prospect is huge.
本发明公开了一种利用水泥废水制备的碱激发混凝土，包括如下原料：水泥废水、碱性激发剂和矿渣。本发明使用水泥废水作为碱激发混凝土的拌合水来源，制备碱激发混凝土；利用水泥废水中的钠钙等离子辅助激发胶凝材料，促使形成强化胶结体，变废为宝、变害为宝，大幅简化水泥废水的处置和利用工艺，减轻建筑企业的经济、安全与环境负担，将废水经济价值提升至城市普通自来水水平，符合国家环保政策要求，应用前景巨大。
