their disintegration due to impact. This characteristic is measured by impact value test. The aggregate impact value is a measure of resistance to sudden impact or shock which may differ from its resistance to gradually applied compressive load. 3. APPARATUS The apparatus of the aggregate impact value test as per IS 2386 Part IV – 1963
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 slowly applied compressive load. With aggregate of aggregate impact value higher than
between aggregate crushing value ACV and ten percent fines aggregate crushing value TFV for some aggregates in Nigeria. Such a mathematical relationship usually established through regression modelling on data collected is useful in saving time and money cost on site through estimating one variable when another is known.

What is the main difference between crushing test and impact test in coarse aggregate.. crushing test helps to determine the aggregate crushing value of coarse aggregates as per IS 2386. Impact test is done to determine the aggregate impact value of coarse aggregates as per IS 2386 Part IV – 1963.
crushing value is defined by the percentage loss in mass on 2.36 mm size of test. Bigger percentage of aggregate crushing value means the aggregate is inferior in quality. According to BS 8821992 aggregate with crushing value less than 25 can be used in heavy duty floor crushing value for more than 30 aggregate to be used in concrete for
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.
