Physicochemical Classification of Nigerian Cement. AU Journal of Technology, Thailand

Abstract

The characterization and classification of cement is based on the determination of its chemical composition and physico-mechanical properties. The set of standards used for this project included the American Society for Testing and Materials (ASTM) and British Standards Institution (BSI) standards. Titrimetric/gravimetric methods of analysis were used. Four major cement samples using various physico-chemical methods were analyzed; two locally manufactured and two imported. Results of all the analysis showed that the locally produced cements, i.e., Elephant and Ashaka, differ in their physico-mechanical properties from the international ASTM and BSI standards. They are better used for structures involved with low load carrying capacities. The Burham cement matched well both in its chemical and physico-mechanical properties and thus can be subjected to structures involved with loading. Dangote cement needs to be further investigated upon. The developed assessment technique based on comparative analysis of ASTM and BSI standards with the technical qualities of the local cement brands can be used to control product quality during manufacturing of cement.
