Limestone deposits and small-scale production of lime in Nigeria

A general survey of limestone deposits in Nigeria is presented. From these deposits five locations representing the geographical distribution of these deposits were selected and hydrated lime prepared from them. An A-7-6 lateritic soil was stabilized with these locally prepared hydrated limes as well as a commercial lime and the results of unconfined compression, CBR and optimum dry density compared. The results show that the locally prepared limes are not inferior to the commercial limes for soil stabilization and strength characteristics. The results also show that because of the low contents of MgO, the limestones were not sensitive to overheating.
