  • Aggregate Crushing Value Test – Determine Aggregate

    Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and the strength of the aggregate used in road construction is expressed by numerical index  Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavementsAggregate Crushing Value Test Determine Aggregate It is recommended that the crushing value of aggregate should be less than 30% If it is more than 30 % then 10% finer aggregate is suggested to use The aggregate whose crushing value is less than 30% can be used for cement concrete road The aggregate whose crushing value is less than 40Aggregate crushing value test Step by Step Procedure
