Akoto, B.K. A. and Singh, G., 1981. Some geotechnical properties of a lime-stabilized laterite containing a high proportion of aluminium oxide. Eng. Geol.,.
The engineering properties of many soils can be improved by lime stabilization. Not all such soils, however, show improved strength. Such non-reactive soils will show no strength increase regardless of lime type and percentage, curing environment and duration of treatment.
The type and amount of minerals and elements may either facilitate or inhibit increase in strength. The strength of soils possessing high proportions of aluminium oxide could be reduced when stabilized with lime and cured over a long period at a high temperature. This decrease in strength is due to the type of reaction products formed.
A Kenyan laterite with a high proportion of aluminium oxide was stabilized with different percentages of lime and cured over periods of up to 28 days. The results show that with a lower percentage of lime, the unconfined strength decreases with increase in curing time. However, when the amount of lime is increased, there is an increase in strength with curing time. The immediate California Bearing Ratio (C.B.R.) values are observed to be functions of density and moisture content. The higher the density, the greater the C.B.R. values.
