Early-strength composite curing agent for improving coastal salinized soil and application of early-strength composite curing agent
The invention relates to an early-strength composite curing agent for improving coastal saline soil and application thereof, and the early-strength composite curing agent comprises the following components: 10.0-40.0% of fly ash, 2.0-4.0% of cement, 5.0-10.0% of lime, 1.0-5.0% of gypsum, 1.2% of aluminum powder, 0.05% of potassium permanganate, 2.0% of magnesium oxide, 0.1-0.25% of a water reducing agent and 0.02% of polyvinyl alcohol. Wherein the mixing amount of each component refers to the percentage of the mass of the components to the mass of the coastal salinized improved soil. The saline soil improved by the early-strength composite curing agent has the advantages of high early-stage and later-stage strength, high deformation resistance, good water stability, difficulty in salt expansion and melt sinking, simplicity and convenience in construction, low treatment cost, capability of fully utilizing industrial wastes and the like.
本发明涉及一种用于改良滨海盐渍土的早强型复合固化剂及其应用，其组分由粉煤灰：10.0‑40.0％，水泥：2.0‑4.0％，石灰：5.0‑10.0％，石膏：1.0‑5.0％，铝粉：1.2％，高锰酸钾：0.05％，氧化镁：2.0％，减水剂：0.1％‑0.25％，聚乙烯醇：0.02％组成，其中各组分掺量是指其质量与滨海盐渍改良土质量的百分比。本发明经过早强型复合固化剂改良处理后的盐渍土早期及后期强度高、抗变形能力强、水稳定性好、不易发生盐胀与溶陷问题以及施工简便、处理费用低、可充分利用工业废弃物等优点。
