Viability of Bauchi Granite as a Finishing Material in Buildings

The paper assessed the viability of some Bauchi granites for application as surface finishes inbuildings. Four granite samples: Pink Bauchite, White Bauchite, White Granite and Granite Gneiss,were sourced from around Sabon Kaura and new Government Reservation Area (GRA) extensionof Bauchi metropolis. The samples were subjected to mineralogy, aggregate impact value,aggregate crushing value and aggregate abrasion value analyses. All the samples, except WhiteBauchite, were found very much suitable for application as wearing-off surface finish with littledifferences in crushing values; white Bauchite was however found to be relatively less suitable forsimilar application due to its comparative weak crushing values. This is perhaps the consequence of the presence of points of possible disintegration, as noticed in the mineralogy analysis. The paper recommends further study on the porosity/ water absorption and permeability analyses of these materials to ascertain the suitability for exterior surface application as well.
