Abstract:

The relationship between Density and Porosity of Rocks from Jos and Environs, North Central Nigeria was established using correlation coefficient of the two parameters that always served as guide on engineering design, especially on strength of materials to be considered. The study is located NE of Naraguta sheet 168, on Latitude 9o 55' 00.00''N - 10° 00' 00.00''N and Longitude 8° 45' 00.00'' E - 9° 00' 00'' E. The Dry Density and Porosity of Rock samples were determined using the Archimedes method guided by the in situ method by Nettleton and Parasnis to determine density, a total of 80 samples were collected. Dry density, Particle density and Porosity were calculated in the laboratory. A correlation was obtained using SPSS and a chart of Porosity vs. Dry Density was plotted. The average Dry Density (g/cm3) and Porosity (%) values for the rocks samples are: Rukuba Granite Gneiss 2.609 and 1.494; Diorites 2.888 and 0.480; Older Basalt 2.942 and 0.356;Aegerine2.663 and 1.831; Naraguta Quartzite 2.615 and 1.469; Jos Biotite granite 2.578 and 1.880; Migmatite 2.643 and 1.617; Neil valley Granite Porphyry 2.638 and 2.164; Hornblende Biotite granite 2.579 and 1.826 and Rhyolite 2.623 and 0.753. The Correlation coefficient values for the rocks are: Rukuba Granite Gneiss -1.0000; Basalt -1.0000; Neil valley Granite Porphyry-0.8362; Hornblende Biotite Granite -0.2909; Naraguta Quartzite -0.2386; Jos Biotite Granite -0.0784; Aegerine-0.0662; Migmatite 0.07997; Diorites 0.36304 and Rhyolite 1.00. From the results of the research it can deduced that for rocks whose density and porosity are related should be considered during engineering design.
