May 17, 2019 Concept 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 (or finer) material obtained when the test aggregates are subjected to a specified load
The values of aggregate crushing test agree in general with that of aggregate impact test. The crushing strength test is most significant as far as the conditions to which the aggregates is likely to be subjected in practice are concerned. The suitability of aggregate in the pavement layers is dependent upon the type of road construction.
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 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 – 12.5mm, 10mm and 2.36mm. Procedure to determine Aggregate Crushing Value
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 ...
The apparatus of the aggregate crushing value test as per IS: 2386 (Part IV) – 1963 consists of: 1) A 15cm diameter open ended steel cylinder with plunger and base plate, of the general form and dimensions as shown in Fig 1. 2) A straight metal tamping rod

Specific gravity and Water Absorption Test of Aggregate major important test to be performed on aggregate. These two parameters or property of aggregate play an important role in the mix design of concrete.As we know that aggregate occupies 70 to 80% volume of concrete, it testing becomes essential before use.
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. Aggregate Impact Value; Test Specifications:
This test method is often used to determine bulk density values that are necessary for use for many methods of selecting proportions for concrete mixtures. The bulk density also may be used for determining mass/volume relationships for conversions in purchase agreements. However, the relationship between degree of compaction of aggregates in a hauling unit or stockpile and that
Volume of dry-rodded coarse aggregate per unit volume of concrete for different coarse aggregates and fineness moduli of fine aggregates ACI Mix Design 8. Estimation of fine aggregate content-- There are two standard methods to establish the fine aggregate content, the mass method and the volume method. We will use the "volume" method.
The test used to determine the TFV is not too dissimilar from the test to determine the aggregate crushing value. This test tends to be used for softer aggregate where a force of 400kn would crush most or all of the aggregate. Generally the higher the value the stronger the aggregate. AGGREGATE IMPACT VALUE, (AIV) The aggregate impact value is ...
Jun 22, 2014 Aggregates used in road construction should be strong enough to resist crushing under traffic. Toughness is the property of a material to resist impact. Due to traffic loads, the road stones are subjected to the pounding action or impact and there is possibility of stones breaking into smaller pieces. The road aggregates should therefore be tough enough to resist fracture under impact.
