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 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 . 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 .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.
crushing test machine for aggregates
The aggregate crushing value test is conducted on coarse aggregates to determine their resistance to crushing under gradually applied compressive load. It is expressed as a percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions. The crushing value of aggregates . aggregate crushing value test in hindiaggregate crushing value test procedureaggregate crushing value test nptelcrushing value test of aggregateaggregate cru.This document describes the procedure for determining the aggregate crushing value (ACV) of aggregate materials. The ACV test involves crushing a sample of aggregate between 9.5mm and 13.2mm under a gradually applied 400kN load. The percentage of material crushed finer than 2.36mm is calculated and reported as the ACV. The test can be performed dry or after .The Crushing Value test measures the ability of an aggregate to resist crushing under a compressive load. It is a measure of the strength and toughness of the aggregate. In this test, a standard crushing load is applied to a prepared aggregate sample, and the percentage of fines generated after the specified amount of crushing is determined.

This video (Animation, Animated Video) explains How to determine aggregate crushing value (Aggregate Crushing Strength). Aggregate test || Coarse aggregate T.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 .
In this test, the aggregate’s resistance is determined to crushing under gradually applied compressive load. a) IS codes for Crushing value Test: IS 2386(Part 4):1963; BS 812–110:1990Aggregate Crushing Value Test | Crushing Value Test | Crushing Value#AggregateCrushingValueTest#CrushingValueTest#CrushingValue#AggregateCrushingValue#Aggreg.Explanation: The polished stone value test is used to test the abrasion of the pavement. It gives a measure of the friction in the pavement also. Roundness can be tested using the shape test, crushing by crushing test and durability by soundness test.The aggregate crushing value test is normally carried out on aggregates between 10 mm and 12.5 mm in scale. In this test, a specified quantity of oven-dried aggregates (about 500g) that .
Crushing Value Test Procedure. Select clean and dry aggregate passing through 12.5 mm and retained on 10.0 mm sieve. Weight the empty cylindrical measure. Let the weight be ‘a’ grams. Fill the aggregate in the cylindrical . Aggregate crushing value = (W1/W2)*100. A value less than 10 signifies an exceptionally strong aggregate while above 35 would normally be regarded as weak aggregates. Also Read: Crushing Test Procedure of .
Figure 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 of Aggregate Crushing Value (ACV) / Ten Percent Fines Value Test . This test is used to measure the strength of the . aggregate. A sample of the aggregate is . crushed in a compression testing machine . The aggregate crushing value test followed the procedure in BS 812–110: 1990 (British Standards Institute, 1990), which is consistent with the Chinese test methods of aggregates for highway engineering, JTG E42-2005, (RIOH, 2005). The tested particle is also selected with a similar round shape, while the particle size is controlled as 9.8 .
