What is The Dry Volume of Concrete and How to Calculate It ...

Fine aggregate (sand) – 20% to 27%; Due to very fine particles, the air void containing-capability of cement is ignored. If we take the highest percentage of air voids in both coarse and fine aggregates, we get, = 34% + 27% = 61%. But when sand and cement are mixed with coarse aggregate, it evaporates some air voids from the coarse aggregate.
