GRADATION OF AGGREGATE FOR CONCRETE BLOCK

1. Strength—The influence of aggregate gradation on the compressive strength of finished concrete block will determine the necessary cement content to produce block which meet specified strength requirements. Since cement is the most costly ingredient in the concrete mix, the selection of a properly graded aggregate assumes an economic aspect. 2.
