“…The DMM is based on mixing binders, such as cement, lime, fly ash, gypsum and other additives, with the soil by the use of rotating mixing tools in order to form columns of a hardening material due to the pozzolanic reactions that occur between the binder and the soil grains (Porbaha, 1998(Porbaha, , 2002Sukontasukkul and Jamsawang, 2012;Voottipruex and Jamsawang, 2014). These DMM piles act as ground reinforcements, thereby increasing the load bearing capacity of the ground (Jamsawang et al, 2011;Voottipruex et al, 2011aVoottipruex et al, ,2011b. The DMM method is often applied in many geotechnical and foundation applications, such as the stabilization of deep excavations or high embankments, slope stability, tunnel support, the reduction of settlement or the increase of bearing capacity of soft compressible soils for building foundations, and water retention (Bergado et al, 1999;Lin and Wong, 1999;Moseley and Kirsch, 2004).…”
