Micro-structural analysis of strength development in low- and high swelling clays stabilized with magnesium chloride solution — A green soil stabilizer

Strengthening montmorillonitic and kaolinitic clays using a calcium-based non-traditional additive: A micro-level study

“…Various underlying mechanisms of soil stabilization can be employed by a given soil improvement process, including mechanical, chemical, biological, and electrical means (e.g., Arulrajah et al, 2013;Bo et al, 2014;Du et al, 2013Du et al, , 2014aDu et al, , 2014bHorpibulsuk et al, 2006;Jiang et al, 2015;Kavitha et al, 2015;Latifi et al, 2016b;Latifi et al, 2015aLatifi et al, , 2015bLatifi et al, , 2015cLatifi et al, , 2015dMarto et al, 2013;Shen et al, 2013aShen et al, , 2013bWu et al, 2015). Among these alternatives, chemical stabilization has emerged as a cost-effective and flexible option, which is commonly deployed in conjunction with a physical or mechanical soil improvement approach (e.g., Al-Mukhtar et al, 2010;Latifi et al, 2014;Liu, 2007).…”

Evaluation of Strength Properties of Sand Modified with Organic Polymers

“…Chemical reinforcement for soil improvement is a popular method using additives such as traditional stabilizers and non-traditional additives. The traditional chemical stabilizers such as lime, fly ash, zeolite gypsum, cement, and other industrial wastes have more advantages for the improvement of soil strength [1][2][3][4], but most of the traditional additives easily increase the pH value of soil, resulting in the environmental problems of polluting ground water or obstructing vegetation growth [5,6]. Recently, non-traditional chemical additives such as liquid polymers, enzymes, ions, and lignin derivatives have been studied [7][8][9].…”

Compression Behaviour of Highly Expansive Clays Stabilised With a Green Stabiliser of Magnesium Chloride

“…There is quite limited research on the performance of treated clays with MgCl2 in the literature [16,18]. Nevertheless, more research is still required to investigate the effect of MgCl 2 on the swelling pressure of expansive clays with different mineralogies.…”

“…On the other hand, there are a number of nontraditional chemical stabilizers which are increasingly being investigated for their effectiveness in treating expansive clays for the past two decades [15][16][17][18]. Chemical stabilizers as an alternative to the traditional calcium-based stabilizers are comprised of combinations of liquid polymers, resins, ions, silicates, acids, and lignin derivatives [16,17].…”

“…Chemical stabilizers as an alternative to the traditional calcium-based stabilizers are comprised of combinations of liquid polymers, resins, ions, silicates, acids, and lignin derivatives [16,17]. These chemical stabilizers are normally concentrated liquids diluted with water or powder dissolved in water and then sprayed on the problematic clayey soils (e.g.…”
