...Rija Johny, MTech; Benny Mathews Abraham, PhD; Asuri Sridharan, PhD Marine clays possess poor engineering properties and need to be improved prior to any construction activities. Lime stabilisation is a widely adopted method of chemical stabilisation for such types of soils. This paper evaluates...

...R. Bouferra; I. Shahrour This paper concerns a study of the influence of fines on the resistance to liquefaction of a clayey sand. The study is carried out using a triaxial apparatus on a reconstituted sand-clay mixture containing a low fraction of clay. After a description of the soil used...

... prepared by using silica fume, fly ash, clay, and cement in different percentages. The properties of these cement-based grouts were determined to obtain the desired optimum values for grouting. Then these grouts were penetrated into the granular soil samples under pressure. The results of this study have...

Lime modification reactions due to increased pore salinity and exchangeable calcium ions suppressed the plasticity index and swell potential, and slightly increased the unconfined compressive strength of the compacted expansive soil. Dans cet exposé, nous examinons la capacité des...
