Experimental investigation on stabilization of clay soil using nano-materials and white cement

Feasibility of Using Nanosilanes in a New Hybrid Stabilised Soil Solution in Rural and Low-Volume Roads

“…Kulanthaivel et al [27] studied the effect of using synthesised Nano-SiO 2 by a solgel process together with cement to stabilise clay soil, concluding that a 7% addition of nano-SiO 2 improves the unconfined compressive strength in a ratio of 5:24 and reduces the permeability in the range of 0.01976 cm/s-0.01198 cm/s of the soil, which is consistent with previous studies [28].…”

“…Although a large number of nanoparticles has been developed, the pozzolanic capacity of Nano-SiO2 and its reactivity with lime and cement to form calcium silicate hydrate (CSH) compounds have led most studies to focus on it [27][28][29][30][31].…”

Application of Nature-Based Nanotechnology for Enhancing Biocementation in Clay by Microbially Induced Calcium Carbonate Precipitation

“…The microscopic imagery showed that the silica nanoparticles enhanced the pozzolanic reaction by transforming Portlandite into Calcium Silicate Hydrate (C-S-H). In another study, clay samples were treated by nano-SiO 2 and white cement separately and in combination [9]. It was observed that nano-SiO 2 alone performed better than white cement alone (at the optimum dosage of 7%) in soil stabilization.…”

“…It has also been reported that overuse of nano-MgO causes cracks in the soil structure. In another study, a fine-grained natural soil containing 36.5% silt and 38.1% clay was stabilized with a combination of different percentages of white cement and nano-silica (nano-SiO 2 ) [9]. Soil properties such as permeability, California Bearing Capacity (CBR), and UCS have been modified.…”
