Advantages aggregate crushing value test report.Aggregate crushing value test is 2386part 4 quality of pavement aggregate possessing low aggregate crushing value to determine the aggregate crushing value by compressive testing machine results the mean of the crushing value obtained in the two tests is reported as the.
Do the calculations as set out in sabs method 842 and report the force to the nearest 10 kn for forces of 100 kn or more, or to the nearest 5 kn for forces of less than 100 kn, on form b43 or a similar form.Reference sabs method 842 s.Bureau of standards standard methods sabs method 842 fact value 10 fines aggregate crushing value of.
As per is 383 this apparatus is used to measures resistance of an aggregate to crushing under a gradually applied compressive load.Specification consists of m.Cylindrical container 150 mm 0.5mm dia x 130mm to 140mm high with base plate 200 to 230 mm.A plinger of 148mm 0.5mm dia x 100 to 115mm high.
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.
As a leading global manufacturer of crushing and milling equipment, we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete stone crushing plant.
The aggregate crushing value acv test set provides a relative measure of the resistance of an aggregate to crushing under a gradually applied pressive load each set consists of steel cylinder, plunger, base plate, cylindrical measure and tamping rod get price aggregate crushing value test report discussion get price.
Aggregate crushing value test report nigeria.Doc aggregate crushing value test lab report adnan the value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality 2 aggregate crushing value.45 for aggregates used for concrete for nonwearing surfaces and 25.
An aggregate specimen is compacted into a steel cylinder fitted with a no-friction plunger.The specimen is then loaded via the plunger.The load crushes the aggregate to an extent depending on the crushing resistance of the material.It is measured by a sieving test on the crushed specimen and it is a measure of the aggregate crushing value acv.
Report the mean as the aggregate crushing value, unless the individual results differ by more than 0.07 times the mean value.In this case repeat the test on two further specimens, calculate the median of the four results to the nearest whole number and report the median as the aggregate crushing value.A data sheet is given as form 7.
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.Each set consists of steel cylinder, plunger, base plate, cylindrical measure and tamping rod.All parts of the apparatus are powder coated or galvanized steel, heat treated and ground.
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.Where, w a is weight of surface-dry sample.
Aggregate crushing value and its test procedure one of the test in which concrete material can fail is due to crushing under compressive stress.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 12.5mm and retained on.
Determination of aggregate crushing value.How to find aggregate crushing value and its test.The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load.The aggregate crushing value test is a useful guide when dealing with aggregates of unknown performance, particularly when lower strength is suspected.
The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the is sieve 2.36mm and the weight of the dried aggregate sample.At least three samples should be tested from the same batch and average value to get accurate results.
Report the mean as the aggregate crushing value, unless the individual results differ by more than 0.07 times the mean value.In this case repeat the test on two further specimens, calculate the median of the four results to the nearest whole number, and report.
The aggregate crushing value acv provides relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load.Two versions available 150 standard and 75 mm dia.The apparatus comprehend cylinder, plunger, base plate, tamping rod and measure.Cylinder, plunger and base plate are made from special alloy.
Report the mean as the aggregate crushing value, unless the individual results differ by more than 0.07 times the mean value.In this case repeat the test on two further specimens, calculate the median of the four results to the nearest whole number, and report the median as the aggregate crushing value.
Aggregate crushing value test report discussion.1 aggregate crushing value report.77 aggregate crushing value and 10 fines value 771number report the mean as the aggregate crushing value unless the individual results differ by more than 007 times the mean value in this case repeat the test on two further specimens calculate the median of the four results to the nearest whole number and report.
