Effect of Continuous (Well-Graded) Combined Aggregate Grading on Concrete Performance, Phase B: Concrete Performance

Based on aggregate packing tests conducted at four locations, the Phase A report concluded that the use of “well graded combined aggregates” (WG) does not necessarily lead to a reduction in the voids content of the aggregate as compared to the “not well graded combined aggregates” (NWG). The aim of this Phase B report is to evaluate whether the use of WG improves the fresh and hardened properties of concrete.
