Recommendations for coarse aggregate testing

This research project investigates current used and potential test methods for evaluating coarse aggregate for use in portland cement concrete. Testing focused on determining the most appropriate aggregate property to evaluate and then determining the correlation to mechanical concrete properties. Relationships between potential aggregate tests and currently used aggregate tests were evaluated to

How to Choose Quality Coarse Aggregate for

Coarse aggregate should contain various fraction sizes to ensure adequate compaction of particles, hence resulting in increased density and reduced voids in concrete. In the majority of concrete works, aggregate sizes of 20 mm or smaller are used. To ensure good coarse aggregate compaction and higher concrete density, it is recommended to mix
