The aggregates crushing value test should be performed as per is code 2386 part iv.First, fill the sample aggregate with one-third of the cylindrical measure in three layers each layer should be tamped 25times freely.
The aggregate crushing value is a numerical index of the resistance of an aggregate to crushing under a gradually applied compressive load.It is expressed as the percentage by mass of the crushed or finer material obtained when the test sample is subjected to a specified load under standard conditions.
Aggregate crushing value - civil engineering.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 12.
The specimen is subjected to a compressive load of 40 tonnes gradually applied at the rate of 4 tonnes per minute.Then crushed aggregates are then sieved through 2.36 mm sieve and weight of passing material is expressed as percentage of the weight of the total sample which is the aggregate crushing value.
Aggregate crushing value as per astm.Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements crushing value of aggregates indicates its strength lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more economical.
2 crushed stone sand - fine aggregate produced by crushing hard stone.3 crushed grace1 sand - line aggregate produced by crushing natural gravel.2 coarse aggregate -- aggregate most of which is retained on 475-mm is sieve and containing.
10 fines aggregate crushing value bs 812 111.Aggregate crushing value and ten percent fines value aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load ten percent fines value used for testing aggregate smaller than 10 mm comprises 150 mm or 75mm diameter steel cylinder plunger base plate tamping.
They also suggested that there was a linear relation between 7.5 fines range, passing through the coordinates 0.4 in the fines versus load diagram, irrespective of rock types.Based on this assumption, they proposed a means of estimating the ten per cent fines load of aggregate from the crushing.
Crushing value of the aggregate as per is construction waste crusher construction waste refers to the construction, construction units or individuals to construct, lay or demolish all kinds of buildings, structures and pipe networks, etc., and generate the spoil, spoil, waste, residual mud and other wastes generated during the repairing process.
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 10mm is sieve is selected and dried to a temperature of 105 c to 110 c then cooled to room temperature.To fill the cylindrical measure mould about 6.5 kg of a sample of aggregate is sufficient.
Aggregate crushing value as per bs812 part 3.Aggregate crushing value as per bs812 part 3.Aggregate impact value bs 812 part 3 1 objective to determine the aggregate impact value in the laboratory 2 introduction impact value of an aggregate is the percentage loss of weight particles passing 236mm sieve by the appliion of load by means of 15 blows of standard hammer and drop under.
Aggregate crushing value significance.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 or finer material obtained when the test aggregates are subjected to a specified load under standardized conditions and the.
