Mechanical Properties of Aggregates Aggregate Crushing Value Test Discussion • There is no explicit relation between the aggregate crushing value and its compressive strength but, in general, the crushing value is greater for a lower compressive strength. BS 812 Part 3 specifies a maximum limit of 30 for aggregates used in structural concrete and 40 on aggregates used in lean concrete.The aggregate crushing value (ACV) which gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The method is applicable to aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve. For other size fractions, there is another recommended method.

For basic crystalline materials in particular, only the Durability Mill Index.
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.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.
Aggregate crushing value discussion. Aggregate Crushing ValueTest - Procedure And . 2021-1-21 Sampling forAggregate Crushing ValueTest For theAggregate crushing valuetest, anaggregatesample 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.Aggregate Crushing Value (ACV) = 3107.4 100 = 40.60 . 6.0 DISCUSSION During the laboratory the dry test was conducted, that is, the aggregate was in surface dry condition. The procedure was followed up to giving results of the tests. These tests are a measure of the crushing properties of the aggregate.
Aggregate Crushing Value Test Report Discussion. Aggregate impact and crushing testlinkedin slideshare aggregate impact and crushing test . is recorded to the nearestwhole number as the aggregate impact value.the aiv is normally about 105 per cent of the aggregate crushing value and itcan be used for the same purpose. . e.g.,australia and new zealand, only use the latter test.discussion.RESULTS AND DISCUSSION . The aggregate crushing value is an essential index in the construction of road bases and is defined as the mass percentage of fine particles after a confined.
The crushing value of aggregates is rather insensitive to variation in strength of weaker aggregates. For this reason, a simple test known as 10 percent fine value is introduced. When the aggregates crushing value become 30 or higher, the results are likely to be inaccurate. Aggregate Crushing Load (Source IS 2386(Part 4) 1963) The aggregates.Oct 04, 2020 The aggregate impact values are higher (on the average, by about 5) than the aggregate crushing values. Various agencies have specified the maximum permissible aggregate impact values for the different types of pavements, those recommended by the.
Aggregate Crushing Value and Its Test Procedure One of the test in which concrete material can fail is due to crushing under compressive stress.

Where, W A is weight of surface-dry sample.
Aggregate Impact Values, (AIV’s), below 10 are regarded as strong, and AIV’s above 35 would normally be regarded as too weak for use in road surfaces. Aggregate Impact Values and Aggregate Crushing Values are often numerically very similar, and indicate similar aggregate strength properties.
