Constitutive relations of coral aggregate concrete under ...

This is because CAC20 contains more fine coral aggregate than CAC40. As approximately 25% of coral sand are fine particles with a diameter less than 160 μm, the fine sand acts as mineral powder filler and makes CAC gain a denser inner structure. Thus, CAC20 shows better ductility than CAC40. Download : Download high-res image (330KB)
