Cost Evaluation of Producing Different Aggregate Sizes in Selected Quarries in Ondo State Nigeria

Abstract

This research centres on cost evaluation of producing aggregate sizes in selected quarries in Ondo State, Nigeria. In this study, two granite quarries out of the quarrying companies in Ondo State are used as case studies. In order to achieve the aim of this research physical properties of aggregate and stages involve in aggregate production were discussed. Also, structured questionnaires were distributed to the mangers and other management staff in the selected quarries to acquire the total cost implication of producing 1 ton of granite aggregate. The data acquired was subjected to basic economic evaluation. The results show that the monthly operation costfor Quarry A is N 30,618,000, while that of Quarry B is N10,164,000. The total production in volume value isN 67,242,000 for A and that of B is N32,625,000. Base on the above values the profit for A is N37,242,000 while that of B is N22,241,000. These translate to 122% profit for A and 219% profit for B. It is recommended that the cost price of granite aggregates in Nigeria can be reviewed to make it reachable for masses. This will eradicate the use of natural gravels that are not free from clays coating and other fine materials that could affect hydration and bond of cement paste which can lead to building or structure collapse.
