A study of the hydraulic products formation in stabilised clay soils containing fly ash and cements

This experimental work deals with the formation of various hydraulic compounds in stabilized clayey soils containing high lime fly ash and cement. Samples of natural clay were mixed with 10% high lime fly ash. In a part of them 4% of Portland cement has been added. All mixtures at the age of 3,7,28 days and 3,6,and 9 months were studied by X ray Diffractometry ( XRD ) and Thermogravimetry ( TG-SDTA ). The hydraulic compounds observed were the compounds attributed to the reaction of the lime contained in fly ash with the clay constituents, to the hydration of the calcium-aluminium-silicate compounds of fly ash as well as to the hydration of the cement added. In the course of time, the formed hydraulic compounds are increased resulting in better mechanical behavior of the stabilized clay soils.
