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
View Notes aggregate crushing value from CIVIL ENG CIVE3259D at University of Mauritius BRITISH STANDARD Testing aggregates Part 110 Methods for determination of aggregate crushing value
For this reason assessment of strength of the aggregate is made by using a sample of bulk aggregate in a standardized manner This testing method is known as an aggregate crushing value test Aggregate crushing value provides the resistance of an aggregate sample to crushing under gradually applied compressive load
The aggregate crushing value test result should not be more than 30 for the concrete used for roads and pavements and in case of other structures it may be permitted up to 45 c standard guidelines for crushing test followings are the standard guidelines for the crushing test on aggregates
Aggregate Impact And Crushing Test Slideshare Feb 08 2012 aggregate impact and crushing test the nearestwhole number as the aggregate impact aiv is normally about 105 per cent of the aggregate crushing value and itcan be used for the same purpose for weak aggregates the required load for thefirst ten per cent fines test can be estimated by means of the formula 4000 required load kn
Aggregate crushing value civil engineering 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 more details get price Aggregate Crushing Value Test Determine Aggregate
The aggregate impact value of coarse aggregate provides a relative measure of the resistance of an aggregate to sudden shock or impact The oven dried and accurately weighed aggregates are subjected to a total of 15 blows of specified weight and fall and percentage of fines formed in terms of the total weight of the sample is expressed as the aggregate impact value
32 The principal value of this test method is to furnish a warning that organic impurities may be present When a sample subjected to this test produces a color darker than 421 Mix one batch of mortar for the fine aggregate test sample and one batch of mortar for the standard sample All batches shall have the same quantity of fine
