CONCRETE 101- what size aggregate for concrete ,CONCRETE 101 A guide to understanding the qualities of , What aggregate size can we pump and size delivery system must be used? ACI 304 suggests that the maximum size of angular (crushed stone,concrete and increase the early strength of hardened concrete Calcium chloride is widely used in non-structural concrete It canAggregate size| Concrete Construction Magazine | Concrete ,The larger sizes will require less mixing water and hence, for a given cement factor, will produce concrete of lower water-ratio than the smaller siz 3 The advantage of small aggregate in the water-ratio strength relationship may or may not be sufficient to offset the effects of its higher mixing water demand.
