crushing strength of aggregate

The crushing strength test results are presented in Tables 3 to 5, the strength reduces with the increase in the size of aggregate. At 7 days curing, the strength of fly ash aggregate (30G2) was enhanced by 41 % higher compared to that of 1 day curing. The crushing strength of 6 mm size of fly ash aggregate (30G2) showed an increase of 17.36%
