Hence 40 mm down coarse aggregate will require much less water than 20 mm down aggregate. In other words for the same workability, 40mm down aggregate will have lower water/cement ratio, thus higher strength when compared to 20mm down aggregate.
Aggregates make up some 60 80% of the concrete mix. • Aggregates are divided into either ‘coarse’ or ‘fine’ categories. Coarse aggregates are particulates that are greater than The usual range employed is between and in diameter.
