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.

Jul 01, 2019 Procedure of Aggregate Impact value test. The test sample normally aggregates sized 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 10.0 mm IS sieves. The aggregates passing through 12.5 mm sieve comprises the test material.
Apr 08, 2010 In France, the SE value is measured on grain sizes 02 mm with a maximum percentage of 10 fines. If the material contains more than 10 fines in these grain sizes, sand has to be added to lower the value. Product Standard SIST EN 13242 defines the procedure in SIST EN 933-82000 assessment of finessand equivalent test, to be decisive.
There are several criteria for determination of the most appropriate cut-off value in a diagnostic test with continuous results. Mostly based on receiver operating characteristic ROC analysis, there are various methods to determine the test cut-off value. The most common criteria are the point on

Oct 17, 2015 Sand Equivalent Value Test Purpose To determine the percent of undesirable particles in the fine aggregate fraction used in the design of Portland cement concrete mixtures. The method is also applicable for determining the relative proportions of detrimental fine dust or claylike material in soils. Equipment and Materials The Sand Equivalent test kit consists of
SPT blow counts and fines content in the preliminary and supplementary boreholes are shown in Fig. 10.7.Comparison of these results shows that while soil strength down to depths of approximately 8 m was very similar in the preliminary and site-specific SPT boreholes, the thickness of the loose to medium dense sand layer was greater in the latter tests.
Procedure. Step 1 First, the aggregate sample sieve through 12.5mm sieve and collect it which is retained in 10 mm sieve. Step 2 Now, the sample should be dried through the oven up to 4 hours at 100 deg to 110 deg. Step 3 Then, the aggregate sample should be filled in the metal cup by 3 layers. Each layer should be tamped 25 times by the tamping rod.
Importance of Impact Test on Aggregates. The impact test on aggregate is carried out to know the response of aggregates to different kinds of loads that the aggregates will be subjected to during their service life.. The need for impact value test is used to measure the toughness of aggregates which is nothing but the ability of aggregates to resist the sudden loading or impact loading.

Ten per cent fines load and ACV tests are two well accepted tests for assessing the mechanical properties of aggregates. While the load producing ten per cent fines is determined in the former test, the amount of fines produced under 40 ton load is given as ACV in the latter test. Both tests are standardised in the U.K. and carried out in the same way, on the approximately same amount of ...
