A common break pattern is a conical fracture (see figure ). • The concrete strength is calculated by dividing the maximum load at failure by the average cross-sectional area. C 39 has correction factors if the length-to-diameter ratio of the cylinder is between 1.75 and 1.00, which is rare.

Aggregates for Concrete - University of Memphis

The absorption and surface moisture of aggregates should be determined according to ASTM C 70, C 127, C 128, and C 566 (AASHTO T 255) so that the total water content of the concrete can be controlled and correct batch weights determined.

How to Find Aggregate Crushing Value and Its Test Procedure?

Aggregate Crushing value is a measure of the strength of the aggregate. The strength of concrete largely depends upon the strength of aggregate. The aggregate should therefore have minimum crushing value. The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load.
