“…Dispersion of fibers influenced UCS as it may have introduced pockets of weakness/failure planes [8]. Arasan et al (2015) studied the feasibility of utilizing polymers as a binder for rapid stabilization of sandy soils with DSM by conducting UCS tests on different ratios of polyester-soil mix. UCS was observed to increase with increasing polyester ratio, effective diameter, relative density and curing period.…”

“…UCS was observed to increase with increasing polyester ratio, effective diameter, relative density and curing period. The highest UCS achieved was with 0.6-1.18 mm grain size, 30% polyester ratio and 40% relative density respectively [9]. Laboratory studies testing on fiber reinforced soil cement (FRSC) samples of clay soils in Bangkok, Thailand were conducted to investigate effect on flexural performance (bending strength @ L/150 deflection, 150 ) improvement [10].…”

Ordinary Portland Cement (OPC) and Lime (CaO) have traditionally been used as binder materials for Deep Soil Mix (DSM) ground improvement. Research has been conducted into possible alternatives such as pozzolans to reduce reliance on either cement or lime. However, pozzolans still undergo similar calcium-based reactions in the strengthening process. In this review, further alternative binder materials for soil strength development are explored. These recent developments include fiber reinforcement materials, alkali activation methods, nanomaterials and geopolymers, which can potentially achieve equal or improved performance. Research to date has shown that alkali-activated materials and geopolymers can be equivalent or superior alternatives to pozzolanic supplemented cement binders. The case is made for GP cements which potentially produces 80% less CO2 than conventional portland cement during manufacture. One-part AAM and GP cements are a promising substitute for portland cement in DSM. A combined approach which incorporates both Ca and alkali activated/geopolymer types of materials and hence reactions is proposed.

“…The consolidation characteristics are investigated along the marine clay deposits along Northern Arabian Gulf with the aim of proposing a coefficient of consolidation with the stress level of marine clay (Elkateb, 2017). Deep mixing of cement for improvement of strength of marine clay is a method commonly adopted (Shen et al, 2008;Arasan et al, 2015). Further it is seen that the study of the yielding behavior of cement admixed marine clay in terms of its strength suggests that despite several investigations remain elusive in deriving simple relationship for mix ratio (Consoli & Prietto, 2006;Xiao et al, 2014).…”

Strength assessment and improvement of strength parameters are essential to design the foundation in clay and marine clay. Several studies have been made in this aspect. Marine clay is also a potential material for use as liner material to contain landfill leach ate. The applications include use of marine clay for transforming waste into light weight aggregates and thus create better environment. The physical parameters such as Atterberg limits, California Bearing Ratio (CBR) value, dry density, specific gravity, free swell, chemical properties such as p H value, cation exchange capacity, organic matter content, calcium carbonate, and mineralogical composition using X-ray diffraction analysis are studied. The consolidation characteristics, determination of strength improvement strategies using admixtures at different proportions are frequently adopted. Commonly used admixtures are lime, limes mixed with cement, coir, shredded plastics. The consolidation studies are very vital and play an important role.

“…Therefore future research shall focus on realistic modelling of concave corners of such wall structures which can be totally different from diaphragmwall behaviour analysed in present paper. Prediction of deep mixing materials characteristics are a present-day research topic [13] making the issue even more complicated. As a conclusion it can be stated, that no special design technique exists to find an economic solution for walls retaining concave corners.…”
