Unfired ecological building block based on sludge soil solidification treatment and preparation method of unfired ecological building block
The invention relates to an unfired ecological building block based on sludge soil solidification treatment and a preparation method thereof, and belongs to the technical field of sludge soil treatment, the unfired ecological building block comprises sludge soil and a curing agent, the curing agent is a mixture of a component A and a component B, the component A is quick lime, the component B is calcium-based solid waste and comprises carbide slag, slag, fly ash and anhydrous desulfurized gypsum, and the component B is calcium-based solid waste. Wherein the mass ratio of the component A to the component B is (1: 4)-(1: 6); the mass ratio of the curing agent to the sludge soil is controlled to be (0.35-0.55): 1. Based on a sludge soil hydration action mechanism and a pore structure change principle, the method can be used for solving the problems of high water content, high compressibility, low strength, poor stability, low bearing capacity and the like of dredged sludge in the eastern region of China, meanwhile, the comprehensive utilization rate of industrial by-products is increased, and application of green low-carbon engineering materials is facilitated.
本发明涉及一种基于淤泥土固化处理的免烧生态砌块及其制备方法，属于淤泥土处理技术领域，包括淤泥土和固化剂，所述固化剂为组分A和组分B的混合物，组分A为生石灰，组分B为钙基固废，包括电石渣、矿渣、粉煤灰及无水脱硫石膏，其中组分A、组分B的质量比为1:4～1:6之间；固化剂与淤泥土的质量比控制在(0.35～0.55)：1。本发明基于淤泥土水化作用机制及孔隙结构变化原理，可用于解决我国东部地区疏浚淤泥高含水量、压缩性大、强度低、稳定性差、承载能力低等特点，同时提高工业副产品综合利用率，助力绿色低碳工程材料的应用。
