Experimental investigation into the influence of zeolite addition on shallow foundations behavior placed on coastal sand of Mazandaran Sea

The shortcoming of loose sandy soils in terms of shear strength besides placement of a huge number of structures on them drive the critical requirement for exploring the shallow foundations treatment, their positioning and shapes. In this regard, stabilization of loose sandy soils through fabricatin...
