aggregate crushing value conclusion

determination of aggregate crushing value Dronacharya College of 1 To determine the aggregate crushing value of coarse aggregates The apparatus of the aggregate crushing value test as per IS 2386 Part IV – 1963 Report the mean of two observation rounded to

Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements Crushing value of aggregates indicates its strength Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more economical performance

Objective 1 Determine the aggregate crushing value of coarse aggregate 2 Assess suitability of coarse aggregates for use in different types of road Theory The quot aggregate crushing value quot give a relative measure of the resistance of

AGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS 2386 Part IV – 1963 The apparatus used is Cylindrical measure and plunger Compression testing machine IS Sieves of sizes – 125mm 10mm and 236mm

The aggregate crushing value ACV of an aggregate is the mass of material expressed as a percentage of the test sample which is crushed finer than a 236 mm sieve when a sample of aggregate passing the 132 mm and retained on the 950 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN 2 APPARATUS 21 An

The aggregate comprising the test sample shall be dried in an oven for a period of four hours at a temperature of 100110 °C and measuring cup shall be filled about onethird with the aggregate and gives 25 no of blows with tamping rod
