摘要

流态固化土具有高流动性、自密实、强度可控等特点，可解决回填场地狭小、回填空间狭窄等填筑工程难题，其流态固化材料主要包括胶凝组分和流动组分，目前针对淤泥的流态固化胶凝材料和固化机理研究尚不充分。采用矿粉和水泥作为基础胶凝材料，通过单因素试验确定激发剂（生石灰和硅酸钠）的适宜掺量，借助Design Expert软件进行响应面分析，得到复合胶凝材料的优化配比；通过XRD和SEM试验得到固化淤泥的产物种类和微观结构，分析复合胶凝材料的固化机理。结果表明，复合胶凝材料（CCM）中水泥∶矿粉∶生石灰∶硅酸钠的优化配比为38∶42∶9.7∶6.5，采用CCM的流态固化淤泥的流动度和强度均优于仅采用水泥的流态固化淤泥。CCM固化淤泥的水化产物主要包括水化硅酸钙凝胶和钙矾石，水化产物包裹土颗粒并填充孔隙，显著提高了流态固化淤泥的强度。CCM的固化淤泥强度提高包括水化作用、碱激发火山灰反应、离子交换作用、微膨胀和填充作用等。

Abstract

Fluidized solidified soil

due to its high fluidity

self-compaction

and controllable strength

can solve filling engineering problems such as narrow backfill sites and narrow backfill spaces

and fluidized solidified materials mainly include cementitious components and flow components. Using slag and cement as basic cementitious materials

the appropriate dosage of the activators (quicklime and sodium silicate) were determined through single factor tests. Response surface analysis was conducted using Design Expert software to obtain the optimized ratio of composite cementitious materials. The types and microstructure of solidified sludge products were obtained through XRD and SEM experiments

and the solidification mechanism of composite cementitious materials was analyzed. The results showed that the optimized ratio of composite cementitious material (CCM) cement∶slay∶quicklime∶sodium silicate was 38∶42∶9.7∶6.5. The fluidity and strength of the fluidized solidified sludge using CCM were better than those using only cement. The hydration products of CCM solidified sludge mainly include hydrated calcium silicate gel and ettringite. The hydration products encapsulate soil particles and fill pores

significantly improving the strength of fulidized solidified sludge. The strength improvement of CCM solidified sludge includes hydration

alkali induced pozzolanic reaction

ion exchange

micro expansion and filling effects.
