REACTIONS IN LIME-SODIUM CHLORIDE TREATED SOILS

In two earlier papers ("The Highway Engineer", November and December 1982) the authors described triaxial and unconfined compressive strength studies which have been carried out on laboratory prepared samples of sand/clay mixtures treated with (a) lime and (b) sodium chloride and lime. In each case mixtures were made up with (I) commercially prepared kaolinite and (II) commercially prepared montmorillonite. This paper describes the related study in which the reaction products formed during manufacture and curing of clay/lime and clay/sodium chloride/lime mixtures have been investigated by x-ray diffraction, scanning electron microscopy, and energy dispersive x-ray analysis techniques. The study has indicated that the materials formed by reaction (principally calcium aluminium silicate hydrates (hydrogarnets), calcium aluminate hydrates, calcium silicate hydrates and sodium and chloride bearing varieties of these hydrates) are different in these two cases.
