1.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 100 where weight of oven-dried sample weight in of fraction passing through 2.36 mm IS sieve. 6.video aggregate crushing value testaggregate crushing value can be determined by using a simple formula: this test is repeated once or twice and the average crushing value of the aggregate is determined. the average crushing value in the different tests is the actual crushing value of aggregate. important points to remember 1.it is recommended that the crushing value of
coarse aggregates. aggregate. coarse aggregates deleterious materials astm mass percentage of contaminants such as clay lumps, shale, wood, mica, and coal test wet sieving agg. size fraction over specified sieves mass lost contaminants range from 0.2% to 10%, depending upon contaminant aggregate. coarse aggregatesconcept and significance of the aggregate crushing value test. the aggregate crushing value test gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. aggregate crushing value is defined as the percentage by weight of the crushed material obtained when the test aggregates are subjected to a specified load under
aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.sampling for aggregate crushing value test: for the aggregate crushing value test, an aggregate sample passing through 12.5 mm IS sieve and retained on IS sieve is selected and dried to a temperature of 105 to 110 then cooled to room temperature.
sep 12, 2015 crushing test fig-1 crushing test setup. one of the model in which pavement material can fail is by crushing under compressive stress. test is standardized by is: 2386 part-iv and used to determine the crushing strength of aggregates. the aggregate crushing value provides a relative measure of resistance to crushing under gradually applied the oven should dry the collected aggregate sample up to hours at 100 to 110 allow the sample to cool at room temperature. test procedure. the aggregates crushing value test should be performed as per IS code 2386 part iv.

the apparatus of the aggregate crushing value test as per is: 2386 1963 consists of: diameter open ended steel cylinder with plunger and base plate, of the general form and dimensions as shown in fig straight metal tamping rod study of the aggregate crushing test. this report records an investigation of the aggregate crushing test size distribution analyses were performed on various rock types, and this technique was used to investigate possible variables in the test.
abrasion test is the measure of aggregate toughness and abrasion resistance such as crushing, degradation and disintegration. this test is suggested by aashto or astm resistance to degradation of small-size coarse aggregate by abrasion and impact in los angeles machine.ppt on aggregate crushing test in denmark. aggregate crushing value test for ppt,aggregate crushing value test for ppt aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test
the aggregate crushing value test result should not be more than for the concrete used for roads and pavements and, in case of other structures; it may be permitted up to 45%. standard guidelines for crushing test: followings are the standard guidelines for the crushing test on aggregates:note the standard aggregate crushing test shall be made on aggre a 12.5-mm IS sieve and retained on a io-mm IS sieve. If required, or if tR ate passing standard size is not available, other sizes up to mm may be tested but owing to the noilchomo- geneity of aggregates the results will not be comparable with those obtained in the
the aggregate crushing value of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kn. apparatuswhile aggregate crushing value of above would be considered as weak aggregates. according to uche and muhammad acv of a concrete aggregate should not exceed 30%.
aggregate crushing test is standardized by is: 2386 part-iv and used to verify the crushing strength of aggregates. the aggregates should be oven dried, which can passes through 12.m and retained on sieve. the cylindrical steel cup is stuffed in three layers of aggregate. each and every layer is tamped with strokes by the rounded end aggregate crushing value this test helps to determine the aggregate crushing value of coarse aggregates as per is: 2386 1963. the apparatus used is cylindrical measure and plunger, compression testing machine, IS sieves of sizes 12.m, and 2.m. procedure to determine aggregate crushing value
