Solid-waste-based early-strength curing agent and preparation method thereof
The invention relates to the technical field of curing treatment, and discloses a solid-waste-based early-strength curing agent and a preparation method thereof.The solid-waste-based early-strength curing agent is prepared from, by weight, 41.03% of slag powder, 20.51% of fly ash, 15.38% of carbide slag and 23.08% of alkali activator; sludge is taken as a curing object, the mass of wet sludge is taken as a reference, the initial water content of the wet sludge is 60%-70%, and the mixing amount of a curing agent in percentage by mass is 10%-50%; the alkali activator is a mixed solution of water glass and sodium hydroxide solid, wherein the mass ratio of the water glass to the sodium hydroxide solid is 5-5.2; the baume degree of water glass in the alkali activator is 38, the modulus is 3.2, and the density is 1.360 g/cm. According to the solid-waste-based early-strength curing agent and the preparation method thereof, the slag powder, the fly ash and the carbide slag are mixed to prepare the curing agent, a large amount of solid waste is used, and the solid waste is effectively utilized for cyclic utilization, so that the concepts of circular economy and green development are practiced, and the energy consumption is reduced.
本发明涉及固化处理技术领域，公开了一种固废基早强型固化剂及其制备方法，包括如下成分以重量分数的组分：固化剂包括：矿渣粉41.03％、粉煤灰20.51％、电石渣15.38％、碱激发剂23.08％；本发明取污泥为固化对象，以湿污泥质量为基准，湿污泥初始含水率为60％‑70％，固化剂质量百分比掺量为10％‑50％；所述碱激发剂为水玻璃和氢氧化钠固体的混合溶液，其中水玻璃和氢氧化钠固体的质量比为5～5.2；所述碱激发剂中水玻璃的波美度为38，模数为3.2，密度为1.360g/cm。该固废基早强型固化剂及其制备方法，通过采用矿渣粉、粉煤灰与电石渣进行混合制备，通过大量使用固体废物，有效利用固体废物进行循环利用，从而践行循环经济、绿色发展理念，降低了能耗。
