EFFECTIVENESS OF LIME AND CEMENT IN CONTROLLING THE EXPANSION OF CLAY

EFECTIVIDAD DE LA CAL Y EL CEMENTO EN EL CONTROL DE LA EXPANSIVIDAD DE LA ARCILLA

The effectiveness of hydrated lime is here compared with the effectiveness of Pa-350 and Pa-550 ARI cements in the upgrading of the volumetric stability of an expansive clay from the Guadalguivir Valley. It is shown that mixing cement and soil produces slight variations (2 per cent) in the maximum dry density and in the optimum moisture. Cements and hydrated lime lead to decreases greater than 100 per cent in the plasticity index of the soil but the lime has a higher effectiveness since it produces the same decreases with lower amounts. These cements and this lime produce a higher upgrading of the volumetric stability of the expansive clay with a decrease in the effectiveness when the binder content is increased. There are no noticeable differences in the results with both cements and lime. Swelling and shrinkage, without load, are isotropic phenomena in untreated and lime treated soil samples. (TRRL)
