Alkali-activated concrete prepared from domestic sewage
The invention discloses alkali-activated concrete prepared from domestic wastewater. The alkali-activated concrete is prepared from the following raw materials: the domestic wastewater, an alkali activator and slag. According to the invention, the alkali-activated concrete is prepared by using the domestic wastewater as a mixing water source of the alkali-activated concrete, organic and inorganic substances in the domestic wastewater are decomposed by using a high-alkalinity environment of the alkali-activated concrete, and heavy metals in the domestic wastewater are cured; ions such as Na, Ca, K and P in the domestic 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 wealth, the treatment and utilization process of the domestic wastewater is greatly simplified, urban economy, safety and environment burdens 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生活废水制备的碱激发混凝土，包括如下原料：生活废水、碱性激发剂和矿渣。本发明使用生活废水作为碱激发混凝土的拌合水来源，制备碱激发混凝土，利用碱激发混凝土的高碱性环境分解生活废水中的有机及无机物质，固化其中的重金属；利用生活废水中的Na、Ca、K、P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，大幅简化生活废水的处置和利用工艺，减轻城市经济、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。
