Non-calcium-based sludge curing agent and application thereof
The invention discloses a non-calcium-based sludge curing agent and application thereof.The non-calcium-based sludge curing agent is prepared from, by weight, 15-30 parts of water glass, 1-2 parts of auxiliary curing agent, 1-2 parts of anionic surfactant and 70-75 parts of water, and the modulus of the water glass is 2.0-2.8. By adopting the non-calcium-based sludge curing agent disclosed by the invention, soil hardening is not easily caused in the sludge curing process, the non-calcium-based sludge curing agent has relatively low dry density, relatively large void ratio and relatively high permeability, the unconfined compressive strength and water stability of sludge soil can be greatly improved, and the application range of the cured sludge soil is expanded.
本申请公开了一种非钙基淤泥固化剂及其应用，非钙基淤泥固化剂包括如下重量份的原料：水玻璃15‑30份、辅助固化剂1‑2份，阴离子表面活性剂1‑2份，水70‑75份，其中，水玻璃的模数为2.0‑2.8。采用本申请的非钙基淤泥固化剂在淤泥固化过程中不易造成土壤板结，具有较低的干密度、较大的孔隙比、较高的渗透性，可以大幅提高淤泥土的无侧限抗压强度和水稳性，扩大了固化后淤泥土的应用范围。
