But regardless of the mix-design method, there are three characteristics of concrete that we are trying balance: 1. Water content as adjusted by admixtures defines workability. 2. WebAt 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.
