Comparative Study and Interrelationship of the Physical and Mechanical Properties of Coarse Aggregates Produced in Ogun State
This study compares and investigates the relationship between the physical and mechanical properties of granites produced in some parts of Ogun State. Granite Samples were tested for their Specific Gravities, Water Absorptions, Moisture Contents, Aggregates Impact Value and Aggregates Crushing Value in accordance to the relevant standards. Test results were compared with relevant standards and with values from various sites. Regression analysis was used to further determine the relationship between the various properties. Results reveals that although all the samples conform to relevant codes and standards there were variations in test results from one location to the other and between the various sizes obtained from the same location. Statistical analysis reveals that there is significant positive correlation between Moisture Content and Water Absorption, no relationship between Specific Gravity and both Moisture Content and Water Absorption, while the relationship between Aggregate Crushing and Impact value is positive but not significant.
