... ABSTRACT: Using different jet grouting methods and variable diameters, a series of samples have been taken by means of core drilling of jet grouting columns made in soft stratified soil. Average values of the compressive strength, tensile strength and secant modulus are presented...

... ABSTRACT: From the viewpoint of low tensile strength and brittle character of improved soils by the conventional CDM technique, a series of laboratory unconfined-compression and splitting-tension tests was conducted on fiber/cement/alluvial soil composite to evaluate the influence of fiber...
