DOI: 10.1016/j.compgeo.2020.103710
Abstract: It is believed that the relative density (Dr) can affect the internal stability of the gap-graded soils and hence the erosion of their fine particles (i.e. susceptibility to suffusion). This paper investigates the influence of… read more here.

DOI: 10.1016/j.conbuildmat.2020.118552
Abstract: Abstract This paper investigates the combined effects of gap-graded cement blended with supplementary cementitious materials (SCMs) by using response surface methodology (RSM). A three-factor three-level Box–Behnken design (BBD) is used to discuss the following independent… read more here.

DOI: 10.1016/j.sandf.2017.08.009
Abstract: Abstract Soils with a bimodal grain-size distribution (gap-graded soils) can be associated with unimodal or bimodal soil-water characteristic curves (SWCCs). Many equations have been developed to estimate SWCCs using grain-size distribution curves to overcome the… read more here.
