This research work deals with estimating the beneficial effect of using Portland cement for stabilizing residual granitic soils. The mechanical behaviour of stabilized soils was evaluated through compressive strength tests and indirect tensile test using Brazilian method. The durability performance was evaluated by capillary water absorption, loss of compressive strength due to saturation, wet-dry and freeze thaw cycles. Furthermore, low cost activators were used in small quantities in order to enhance the durability and mechanical performance of the mixtures. Results obtained indicate that, as expected, Portland cement is effective in increasing the durability and mechanical performance of residual granitic soils. Furthermore, it was observed that some activators enhance significantly the mechanical performance of soil-cement mixtures, being a worthwhile alternative to the increase of the cement content.
