Abstract

The petrography and geotechnical properties of the granite in Imeke were evaluated with a view to determine its utility potential for construction purposes. The samples used in this study were obtained from Imeke for the petrological analysis and from Setraco Nigeria Limited, Imeke, Auchi, Edo State, for the geotechnical analysis. The sample was subjected to some geotechnical analysis having an average aggregate crushing value (ACV) of 31.2%, Los Angeles abrasion value (LAAV) of 29.6%, specific gravity (SG) of 2.67, (WA) water absorption of 0.1%, flakiness index (FI) of 20.9% and elongation index (EI) of 19.8%, respectively. The result of the geotechnical properties indicates that the granite is suitable for decoration, stone and road construction when compared with British Standard Institution (BSI) and Federal Ministry of Work (FMW) Standards. The granite has a petrographic
average modal composition of plagioclase feldspar (15%), orthoclase feldspar (30%), biotite mica (22%), quartz (23%), and accessory mineral (10%). The result of the petrological and geotechnical analysis was compared and the relationship between them was established.
