Investigation On the Suitability of Metamorphosed Granite In Ilorin Nigeria For Road Construction and Polished Rock

Article scientifique 2022 Anglais

Résumé

Abstract The suitability of metamorphosed granite for road construction and polished rock were investigated. Three samples A, B and C were handpicked from Man Hardi Quarry Ilorin using random sampling method. The samples were subjected to different test namely, chemical analysis, polish value, oxidation properties, compressive strength and hardness test. The chemical analysis shows the silica contents for samples A, B and C are 67.73%, 73.62% and 72.40% respectively, specific gravity obtained are 4.52, 4.80 and 3.60 for sample A, B and C. The oxidation properties test reported with no peeling was observed, the polish stone value (psv) test for the samples resulted in good abrasiveness and produce attractive colour. The values for samples A, B and C are 90.88, 97.36 and 93.71 while respectively compressive strength test estimation obtained were 142.37, 201.62 and 164.62 for sample A, B and C. The Hardness test values are 85.59, 96.84 and 88.11 respectively. Hence, the value obtained from the investigation on the suitability of metamorphosed granites for road construction and polish rock shows that they are good for constructional and polished stonework.
