高压旋喷止水帷幕复合固化剂性能分析

Performance Analysis of Composite Curing Agent for High-Pressure Rotary Jet Waterproof Curtain

摘要: 工业生产排放的各类固体废弃物具有潜在活性，与水泥复配后可有效改善固化剂的多种性能。本文基于由固废材料研发的环保型高压旋喷止水帷幕固化剂，通过室内试验，评价了材料的施工性能、力学性能、抗渗性能等指标。研究发现固化剂的浆液比重、混合泥浆流动度与含水率具有明显的线性相关关系。复合固化剂的混合泥浆稳定性明显优于水泥，离析率比水泥泥浆低2%~5%。随着含水率的提高，混合泥浆的稳定性逐渐降低。复合固化剂固化土具有明显的早强特性、抗折特性与高初始含水率适用性。复合固化剂固化土的抗渗性能在45%初始含水率条件下与水泥土接近，而在含水率高达55%时优于水泥土。

Abstract: Various types of solid waste discharged from industrial production have potential activity, and can effectively improve some properties of the curing agent after being compounded with cement. Based on the environmentally friendly high-pressure rotary jet waterproof curtain curing agent developed by solid waste materials, this paper evaluates the construction performance, mechanical performance, impermeability and other indicators of the material through laboratory tests. It found that the slurry specific gravity of the curing agent and the fluidity of the mixed mud both have an obvious linear correlation with the water content. The stability of the mixed slurry of the composite curing agent is obviously better than that of the cement. The segregation rate is 2% - 5% lower than that of the cement slurry. As the moisture content increases, the stability of the mixed mud gradually decreases. Composite curing agent solidified soil has obvious early-strength properties, flexural properties and applicability of high initial moisture content. The impermeability of soil cured by composite curing agent is close to that of cement soil under the condition of 45% initial water content. But it is better when the water content is up to 55%.
