Use of Deep Cement Mixing to Reduce Settlements at Bridge Approaches

Strength properties of an epoxy resin and cement-stabilized silty clay soil

“…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). Among the binding agents used in the DMM, cement is most commonly adopted because of its appreciable improvement of soil properties, lower cost, and easier storage (Bergado et al, 1996;Khattak and Alrashidi, 2006).…”

A testing procedure for predicting strength in artificially cemented soft soils

“…The strength of treated soft soils is in the order of 100 to 1000 kPa in terms of unconfined compressive strength (Terashi and Juran, 2000). This practice has been widely used, as described by Lin and Wong (1999), Andromalos et al (2001) and Hussin and Garbin (2012). The research group at Federal University of Rio Grande do Sul, Brazil (e.g., Thomé et al, 2005;Consoli et al, 2008Consoli et al, , 2009aConsoli et al, ,b,c, 2010Consoli et al, , 2011Consoli et al, , 2012Consoli et al, , 2013aConsoli et al, ,b, 2014aFestugato et al, 2013;Faro et al, 2015) has been studying key parameters dictating strength and stiffness of lime/cement treated soils.…”

Working characteristics of concrete-cored deep cement mixing piles under embankments

“…Deep cement mixing (DCM) columns and precast concrete piles are two kinds of pile foundation systems widely used to support embankments built over soft soil (Lin and Wong, 1999). The installation method for DCM columns is to cut through soft soils by rotating blades whilst cement is mixed with the soil at the same time.…”
