Compressive Strength and Abrasion Resistance of Concretes ...

The compressive strength and abrasion resistance of concretes were tested between at ages 7 to 70 days and 100 500 revolutions of abrasion wheels respectively. The study revealed that the compressive strength and abrasion resistance had the optimal performance when the coarse aggregate content was 45% and the worst performance when the fine aggregate content was % of the total weight of .

7 Lab Test on Aggregates that we Use in Concrete Construction!

The crushing test on aggregate gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. If the aggregate crushing value is less than 10, it signifies an exceptionally strong aggregate. Whereas, if the crushing value is 35 or above, it would normally be considered as weak aggregates.
