| Abstract | It is important that effective and economical stabilization of
soils for use as road subgrades or sub-bases should be possible in a region where more suitable materials are not readily available. Stabilization with cement is by far the most common method used for
improving the engineering characteristics of a soil but, to date, little attempt has been made to use secondary additives in the soil cement mix. To this end, this investigation was conducted to study the strength and durability characteristics of two tropical clays when stabilized with cement and secondary additives. The secondary additives employed were sodium hydroxide, sodium sulfate, sodium metasilicate, calcium hydroxide, and calcium chloride. Compaction was carried out by statically loading the soil in a cylinder and
strengths were measured by unconfined compression tests after various periods of sample curing. Durability tests were conducted to study the effects of wetting and drying cycles on the stabilized soils. The experimental results show that the effects of the secondary additives depend on the type of soil, type and amount of additive, curing conditions and the amount of cement used in the stabilization.
Only hydrated lime proved successful for stabilization of both the clays, and this is the only secondary additive employed that is economical over the use of cement alone. |
