Treatment of a collapsible soil using a bentonite–cement mixture

Algeria) and cement CPJ 42.5 CEM II/A produced by the cement CPJ 42.5 CEM II/A produced by the cement factory of Ain touta in Batna region (Eastern Algeria). The tests were carried out on reconstituted soil SNT “untreated soil” (sand: 75% and kaolin: 25%), which is considered as a collapsible soil according to the different collapse criteria reported by several authors (e.g. Abbeche et al. [ 2 ], Houston et al. [ 3 ] and Ayadat et al. [ 7 ]). The granulometric curve, the Proctor curves and the geotechnical characteristics of the various materials are represented
