The coarse aggregate used in the development will able to handle this pressure. Due to massive load movement on it, the coarse aggregate will be subjected to constan…
DETERMINATION OF AGGREGATE IMPACT VALUE (AIV) (BS 812-112) Scope: This Part of BS 812 describes methods for the determination of the aggregate impact value (AIV) which gives a relative measure of the resistance of an aggregate to sudden shock or impact.
This document describes a test method for determining the aggregate impact value (AIV) of aggregates, which provides a measure of their resistance to sudden shock or impact. The test involves compacting aggregate samples in a steel cup and subjecting them to 15 blows from a hammer. The crushed material is then sieved and the percentage passing a 2.36mm sieve is …
Why do we use aggregate impact value test? The aggregate impact value test is done to test the compressive strength of aggregate when sudden and immediate impact force acted on it. It is expressed in percentage (%). It should be less …
Calculate the Aggregate Impact Value by dividing the weight of the fraction passing through the sieve by the total weight of the sample, and multiplying by 100. Round the result to the nearest whole number, and report the mean of …
What is the aggregate impact value test? A relative measure of the resistance of aggregate due to the sudden shock or impact on it is called aggregate impact value. Based on the impact value, we can decide whether the coarse aggregate is suitable for construction or not.
Report the mean as the aggregate impact value, unless the individual results differ by more than 0.15 times the mean value. In this case repeat the test on two further specimens, calculate the median of the four results to the nearest whole number, and …
The data from the Aggregate Impact Value Test is analyzed by comparing the Impact Value of the sample to established standards for road construction aggregates. If the Impact Value exceeds the established limit, the aggregate may not be suitable for use in road construction.
The apparatus of the aggregate impact value test consists of: A testing machine weighing 45 to 60 kg and having a metal base with a plane lower surface of not less than 30 cm in diameter. The level and plane concrete floor of a minimum of …
