Effects of maximum aggregate size on fracture behaviors of …

As the maximum aggregate size increased from 9.5 to 19 mm, the fracture energy increased by 47.7% and 86.7% for w/c ratios of 0.35 and 0.4, respectively. 2. For the mixes with the same maximum aggregate size, the increase of water/cement ratio decreased the effective length of fracture process zone. 3.

Aggregate size| Concrete Construction Magazine

At a given water ratio, within the range employed in most structural concrete, smaller maximum sizes of aggregate will tend to produce higher concrete strengths than larger ones. 2. 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 sizes. 3.
