  • What nominal maximum sizes of aggregate are

    Because maximum aggregate size can impact concrete properties such as shrinkage, and also the cost of concrete, the largest aggregate size consistent with the requirements of 26.4.2.1 should be permitted. With the w/cm fixed, the larger the nominal maximum size of aggregates, the lower the cement content for a given consistency. Or, stated differently, for a given cement content, the larger the nominal maximum size of aggregateGRADATION OF AGGREGATE FOR CONCRETE BLOCK,2013-2-8 · feasibility of using an aggregate with some material of larger size. The maximum size possible will depend on the minimum section thickness of the concrete block. Obviously the diameter of the largest particle must be less than the thickness of the web of face shells.
