Effect of coarse aggregate on the interfacial transition ...

2020-1-22  The results show that, for normal weight aggregate (NWA), the aggregate grading is the major influencing factor and, for lightweight aggregate (LWA), water absorption is the major influencing factor; both of these factors have the highest correlation degree with K I. Therefore, to improve the microstructure of the ITZ in concrete, NWA with a large average particle size and LWA with a high

The Behavior of Coarse Aggregate in Florida Concrete

2020-3-9  Si nce coarse aggregate used in concrete is available in a variety of gradations, one of the first variables investigated was prevalence of the size and gradation of the coarse aggregate. Based on the initial data queries of Florida mixes and discussions with FDOT personnel, it was decided to use # 57 stone for coarse aggregate in this research as this gradation is commonly used in FDOT approved
