Aggregate Size For Concrete

coarse aggregate size for concrete

· 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 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

· Other size designations are a result of combining aggregates with different size numbers. So No. 67 is a combination of No. 6 and the less coarse No. 7 aggregate. This means No. 67 falls in between No. 6 and No. 7 in terms of coarseness. No. 57, a blend of No. 5 and No. 7 and so on. In Table 2 of ASTM C 33, No. 9 which is a fine aggregate, is ...
