Procedure to determine Aggregate Impact Value i The cup of the impact testing machine should be fixed firmly in position on the base of the machine and the whole of the test sample placed in it and compacted by 25 strokes of the tamping rod.
2018-2-12.1 Object - This method of test covers the procedure for determining aggregate crushing value of coarse aggregate. NOTE 1 -The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.
Aggregate Crushing Value Test INTRODUCTION Procedure The aggregate passing 12.5 mm IS sieYF and retained on10 mm IS sjeySiis selected for standard test. The aggregate should be in surface-dry condition before testing.
2020-6-15If the aggregate crushing value is less than 10 it signifies an exceptionally strong aggregate. Whereas if the crushing value is 35 or above it would normally be considered as weak aggregate.
2020-4-9AGGREGATE CRUSHING VALUE IS2386Part 41963.
The aggregate crushing value is a numerical index of the resistance of an aggregate to crushing under a gradually applied compressive load.
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.
2020-3-27AGGREGATE IMPACT VALUE TEST AIM To find Impact value of the given aggregate sample. APPARATUS The apparatus consists of an impact-testing machine a cylindrical measure tamping rod IS sieve balance tamping rod and oven. PROCEDURE The test sample consists of aggregates passing 12.
2020-6-8The 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.
2020-3-7The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.
2017-5-29aggregate 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.
2020-6-14Procedure of Aggregate Impact value test The test sample normally aggregates sied 10.0 mm to 12.5 mm. the aggregates should be dried by heating at 100-110 0C for a period of 4 hours and cooled. Sieve the material through 12.5mm and 10.
Calculate Aggregate Crushing Value. The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage the result being recorded to the first decimal place Aggregate Crushing Value W B W A 100.
Aggregate crushing value W1W2100 A value less than 10 signifies an exceptionally strong aggregate while above 35 would normally be regarded as weak aggregates .
The Aggregate Crushing Value ACV Test Set provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.
2020-6-14Procedure for crushing strength of aggregate. Before testing the aggregate should be in surface dry condition.You can achieve the dry condition of aggregate by placing aggregates in an oven for 4 hours at 100-degree Celcius. The aggregates passing through 12.
