Aggregate crushing value Test Lab Report
Result: Aggregate crushing value = 20%. Result Analysis: The value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality. Aggregate crushing value < 45% for aggregates used for concrete for non-wearing surfaces and <25% for wearing surfaces like runways and …

The crushing strength or aggregate crushing value of a given road aggregate is found out as per IS-2386 Part- 4. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement aggregate possessing low aggregate crushing value should be ...
DETERMINATION OF AGGREGATE CRUSHING VALUE
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. APPARATUS The apparatus of the aggregate crushing value test as per IS: 2386 (Part IV) – 1963 consists of:
IMPACT VALUE OF AGGREGATE
The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from its resistance to a slow compressive load. 2.Apparatus Required Fig. 1: Balance Balance should be accurate upto 1 g Fig. 2: Sieves Seives required are 12.5, 10.0 and 2.36 mm Fig. 3: Impact ...

getting reproducible results. On the contrary, the aggregate crushing test is simple, rapid and gives fairly consistent results. Application of Aggregate Crushing Test: The aggregate crushing value is an indirect measure of crushing strength of the aggregates. Low aggregate crushing value indicates strong aggregates, as the crushed fraction is low.

Thus, two tests are made for the same specimen for taking an average value. Calculation: The aggregate crushing value is defined, as a ratio of the weight of fines passing the specified IS sieve to the total weight of the sample expressed as a percentage. Aggregate crushing value = 100 W2 W1 Where, W1 = Total weight of dry sample.
