Procedure to determine Aggregate Crushing Value i) The aggregates passing through 12.5mm and retained on 10mm IS Sieve are oven-dried at a temperature of 100 to 110 o C for 3 to . This video (Animation, Animated Video) explains How to determine aggregate crushing value (Aggregate Crushing Strength). Aggregate test || Coarse aggregate T. 2.2.1 Aggregate Crushing Value (ACV) Test: The sample was placed in a cylindrical mould to a . depth of 100 mm in 3 layers, with each layer been . tamped 25 times with tam ping road.
Aggregate Crushing Value Test.The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement, aggregates possessing low aggregate crushing value should be preferred. Why to test Aggregate Crushing Value? The principal mechanical properties required in road stones are:This document gives the determination of aggregate crushing value (ACV) of aggregates. This gives a relative measure of the resistance of the aggregate crushing under the 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. The strength of coarse aggregates is assessed by aggregates crushing test. The aggregate crushing value provides a relative measure of resistance to crushing.
The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied crushing load. The test consists of subjecting the specimen of aggregate in standard mould to a compression test under standard load conditions (See Fig-1).
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 . a mass of material to determine the aggregate 10% fines value. b) Test specimen in a dry condition (i) Sieve the entire dried test portion on the 14 mm and the 10 mm test sieve to .
The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead. 2. apparatus requiredFigure 1 — Outline form of cylinder and plunger for aggregate crushing value test. The surfaces in contact with the aggregate shall be machined and maintained in a smooth condition and preferably case hardened. 6.3 Tamping rod, made out of straight iron or steel bar of circular cross-section, diameter ofAggregate Crushing value test IS Code is 2386-4 (1963): Methods of Test for Aggregates for Concrete. Aggregate Crushing Value Apparatus. Aggregate Crushing Value Apparatus . A 15 cm dia. Steel cylinder with the plunger and base plate. A straight metal tamping rod 16mm in diameter and 45 to 60 cm long rounded at one end.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 of circular cross-section 16mm diameter and 45 to 60
The aggregate crushing value test (ACV, BS 812-Part-110) is one of the test methods for determining the crushing resistance of the aggregates. Alvarado et al. and Reyes et al. concluded that the ACV test was practical, reproducible, and stable and is a pivotal method in the evaluation of aggregate crushing resistance. Friction .

Water Absorption Test . 2.2 Aggregate crushing value test (ACV) & Aggregate . impact value test (AIV) Each aggregate sample was tested in the laboratory for crushing . value and impact value following the specification . This test is similar to the Aggregate Crushing Test (ACV), which applies a standard force of 400kN and expresses the fines material as a percentage of the original mass, known as the aggregate crushing value. The granular sub-base is subject to repeated loadings from various truck types, causing high levels of stress at the contact points of .

Supplied complete with cylinder, plunger, base plate, tamping rod, and measure. Features: Heavy Gauge Steel; Galvanized or Powder Coated; Used for measuring of resistance of aggregate to crushing
The aggregate crushing value (ACV) of an aggregate is the mass of material, expressed as a percentage of the test sample. which is crushed finer than a 2,36 mm sieve when a sample of aggregate passing the 13,2 mm and retained on the 9,50 mm sieve is subjected to crushing under a gradually applied compressive load of 400 kN. 2 APPARATUS 2.1 An .Chapter 3—Aggregate properties and test methods, p. E1-2 3.1—Grading 3.1.1—Definition and test method . aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone. Crushing, screening, . with typical range values, are shown in Table 2.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 .
The crushed aggregate is then sieved, weighed, and compared to the original total weight to provide an aggregate crushing value. Impact test – determines the resistance of aggregates to impact forces. Multiple layers of sieved samples are tamped 25 times before a 14 kg hammer is dropped for a total of 15 blows. The resultant sample is sieved .
Objective: 1. Determine the aggregate crushing value of coarse aggregate. 2. Assess suitability of coarse aggregates for use in different types of road. Theory: The " aggregate crushing value " give a relative measure of the resistance of
Roundness can be tested using the shape test, crushing by crushing test and durability by soundness test. 2. If the aggregate impact value lies between 10 – 20%, the aggregate is said to be ______
