Significance of Aggregate Crushing Value Test The crushing value test is conducted on aggregates that are used for the construction of roads Lower crushing value aggregates give much more durability for roads due to its lower crushed fraction under the compression load The road is subjected to motion pressure continuously.
Aggregate Crushing Value Test is important to test to be performed on aggregate The strength of aggregate parent rock is determined by preparing a cylindrical shape specimens of size 25 mm diameter and 25 mm height This cylinder is subjected to compressive stress.
If it is more than 30 then 10 finer aggregate is suggested to use The aggregate whose crushing value is less than 30 can be used for cement concrete road The aggregate whose crushing value is less than 40 can be used for wearing surface This test must be done before it comes to road and pavement construction.
This resistance of aggregate may differ from resistance to gradual load which we measure in the crushing value test Importance Impact Value Test Generally the majority of the aggregate test is carried out to know the response of aggregates to different kinds of loads that the aggregates will be subjected to during their service life.
Jul 16 2014018332It has been found that for majority of aggregates the aggregate crushing value and aggregate impact values are numerically similar within close limits For deciding the suitability of soft aggregates in base course construction aggregate impact test is commonly used.
The Aggregate Crushing Value gives a relative measure of the resistance of the aggregate to crushing under a gradually applied compressive load 7 7 1 2 Scope The particular purpose which an aggregate is meant to serve requires the aggregate to have a particular strength This strength is usually stated in the specification.

Jun 22 2014018332Significance of Test Aggregates used in road construction should be strong enough to resist crushing under traffic Toughness is the property of a material to resist impact Due to traffic loads the road stones are subjected to the pounding action or impact and there is possibility of stones breaking into smaller pieces.
Jan 09 2018018332Aggregate Impact Value Test AIV test is conducted to determine the Aggregate Impact Value of Coarse 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 compression load The Indian Standard CODE IS 2386 Part IV 1963 is used for procedure and.
Aggregate Impact Values AIVs below 10 are regarded as strong and AIVs above 35 would normally be regarded as too weak for use in road surfaces Aggregate Impact Values and Aggregate Crushing Values are often numerically very similar and indicate similar aggregate strength properties Aggregate Impact Value Test Specifications.
Aggregate Impact Value on Coarse Aggregates Apparatus for Aggregate Impact Test The apparatus as per IS 2386 Part IV 1963 consists of i A testing machine weighing 45 to 60 kg and having a metal base with a painted lower surface of not less than 30 cm in diameter.
The determination of aggregate crushing strength is an important test in your civil engineering lab You know that aggregates are the one the basic unit of building materials Aggregates are used in several construction processes such as in concrete road construction etc.
Mar 22 2018018332The aim of aggregate impact test is to determine the relative measure of the resistance of aggregate to sudden shock or impact in which in some aggregate differs from its resistance to a slowly applies compressive load The property of a material to resist impact is known as toughness.
Importance Of Aggregate Crushing Value Test Jun 13 2019 the crushing value of aggregate is very important to know the strength of the aggregate for finding the resistance of aggregate under gradually applied compressive load the crushing value test of aggregate is done for the crushing value test the following procedure is followed procedure for finding the crushing value of More Details.
