DETERMINATION OF AGGREGATE CRUSHING VALUE

The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Crushing value is a measure of the strength of the aggregate. The aggregates should therefore have minimum crushing value. 3.

Rankin's Formula Example for Column .

06.12.2014 · If column is short, calculated load will be known as crushing load. And load will be buckling or crippling load, in case of long column. This formula only gives the ultimate load, but columns are design on safe load. In order to get safe load, divide ultimate load ( Load obtained from Rankin's Formula) with factor of safety (F.O.S).
