Crushing Value For Ordinary Concrete

Aggregate Crushing Value Test Determine Aggregate Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load 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 What Should Be Thecrushing Value For Ordinary Concrete What should be thecrushing value for ordinary concrete concrete crushing strength the crushing strength of concrete determined by breaking a cube and often called the cube strength reaches values of about 3 tons per square inch that of granite 10 tons per square inch and that of cast iron from 25 to 60 tons per square inch Major Ingredients And Raw Materials Of Aggregate crushing value note a value less than 10 signifies an exceptionally strong aggregate while above 35 would normally be regarded as weak aggregates table 1 limit value of crushing nt building crushing value limit flexible pavement i soling 50 ii water bound macadam 40 h1 h2
