Abstract: Abstract— Granites are sourced for construction aggregates viz, rock flour, crushed stones. They are also cut and polished for floor and wall tiles and other building accessories. Larger pieces of granites are used as surcharge materials to stabilize construction sites like petrol-filling station. In Nigeria, granites are sought for completion of road pavements and airport run ways. Varieties of granites having different textural characteristics and mineralogical composition are found on the Jos Plateau Nigeria. This paper presents data of engineering/rheological investigation of selected granites from Jos Plateau, The Jos-Bukuru and the Ropp complexes were studied and sampled between 2003 and 2006. Selected granite samples were cut with diamond studded saw blades into cubes (size 40mm x 40mm x 35mm). The cubes were subjected to imaxial/compression with the mechanized and computerized UTM machine model 50KN. The specimens were compressed to failure, marked by cracks/partings on the specimen surface(s) several rheological parameters viz, stress @ peak, load @ peak, strain @ peak and others were measured and recorded by another computer. The data collected are presented as tables and graphs in this report. The specimens exhibit data which show that they represent materials good for engineering construction and concrete aggregates. The granites may be classified by Deere and Miller criteria as high or very good for construction works.
