Abstract

The suitability of the blend of calcium carbide residue and hydrated lime to serve as a stabilizing agent, in order to overcome the challenge of availability and high cost of hydrated lime in Nigeria was investigated. Calcium carbide residue was replaced with hydrated lime in incremental order of 10 %, from 0 % to 100 %. The blend of calcium carbide residue partially replaced with hydrated lime was used in incremental order of 2 % from 0 % to 8 % to treat laterite soil obtained from Ikpayongo. The sample of laterite soil treated with different percentages of the blend of calcium carbide residue and hydrated lime were subjected to Atterberg’s limits test, compaction test, unconfined compression strength test, durability test and California bearing ratio test. Based on result of test calcium carbide residue partially replaced with 70 % hydrated lime is recommended for use as a stabilizing agent. The use of calcium carbide residue as a stabilizing agent will provide an effective way of disposing calcium carbide residue which has negative impact on the environment, in addition to ensuring economy in the use of lime in soil stabilization
