Study on the Durability of Hydraulic Lime Soil Mixed with Sodium Methyl Silicate

Natural hydraulic lime soil has good mechanical properties; as an earthen ruin restoration material, its durability is insufficient. Despite natural being a topic that been studied for several years from different researchers, it not yet fully considered the improvement of durability. This work aims to experimentally investigate enhancement properties lime-based. The performance limestone by adding sodium methyl silicate and organic silicon examined effect on microstructure studied. 6%, 10%, 15% lime–soil comparison test blocks were compared with mixed silicate; in addition compression resistance, shear water absorption, erosion dry–wet cycles carried out, well testing analysis. results show enhances compressive strength lime-modified soil, reduces saturated strength, improves resistance dry wet cycles, forms surface modified particles. hydrophobic layer further resistance. When content 0.3%, durability, which optimal ratio.
