aggregate crushing value of coarse aggregate. NOTE 1 -The 'aggregate crushing value' gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggre- gate of 'aggregate crushing value' 30 or higher, the result may be anomalous, and in
affected. The strength of coarse aggregates is assessed by aggregates crushing 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, aggregate possessing low aggregate crushing value should be preferred.

Aggregate Crushing Value Test is an important test to be performed on aggregate. The strength of aggregate parent rock is determined by preparing cylindrical shape specimens of size 25 mm diameter and 25 mm height. IS Code For Crushing Value Test. Aggregate Crushing value test IS Code is 2386-4 (1963): Methods of Test for Aggregates for ...
The crushing strength or aggregate crushing value of a given road aggregate is found out as per IS-2386 Part- 4. 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 aggregate possessing low aggregate crushing value should be ...

The compressive strength test is carried out either on a cube or cylinder by breaking the concrete specimen in a compression testing machine and it is calculated from the failure load divided by the cross-sectional area of the cube or cylinder resisting the load and reported in units of pound-force per square inch (psi) in US Customary units or ...
Then crushed aggregates are then sieved through 2.36 mm sieve and weight of passing material (W2) is expressed as percentage of the weight of the total sample (W1) which is the aggregate crushing value. Aggregate crushing value = (W1/W2)*100. A value less than 10 signifies an exceptionally strong aggregate while above 35 would normally be ...
crushing process. We are the world's leading supplier of both unit machines and complete aggregates processing systems. Comprehensive process solutions Your system may involve a whole series of proc-esses, such as crushing and screening, conveying, classifying, washing and pretreatment, stockpil-ing, storage, loading and unloading, automation,
Aggregate Crushing Value (ACV) test indicates the resistance to crushing under gradually applied crushing load. It is measured as percentage of aggregates passing through 2.36 mm IS sieve after specimen subjected to a compressive load of 40 tonne at the rate 4 tonne per minute and to the weight of aggregates taken.
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.
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 …
Sieve the test material through 12.5 mm and 10.0 mm IS sieve. Take test samples of aggregates passing through 12.5 mm IS sieve and retained on 10 mm IS sieve (minimum 3 Kg).; Dry theme in an oven for 4 hours at a temperature of 100 °C to 110 °C and then cool at room temperature.
Crushing test and Impact test are very important to estimate strength and toughness characteristics of the road aggregate. Extensive experimental procedures and different sets of equipment are ...
aggregate to crushing under a gradually applied compressive load. Crushing value is a measure of the strength of the aggregate. The aggregates should therefore have minimum crushing value. 3. APPARATUS The apparatus of the aggregate crushing value test as per IS: 2386 (Part IV) – 1963 consists of:
Aggregate crushing value is the measure of resistance of aggregate to crushing against gradually applied compressive load. This test is conducted to determine the crushing strength of aggregate. This test helps to assess the suitability of aggregates for use in road construction and other applications where they are subjected to high ...
The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer …

Crushing Strength Test on Aggregates: The crushing strength of aggregates is a paramount property, indicating their ability to endure applied loads. ... Load Application: The plunger is inserted, and the assembly is placed on a compression testing machine. A uniform load of 40 tonnes is applied in 10 minutes. Sieving and Calculation: ...
A test is recognized with IS:2386 part-IV and conducted to find out the crushing strength of aggregates. The crushing value of aggregate offers a relative measure of resistance against …
The crushing characteristics of coarse aggregates for asphalt concrete were investigated under static and dynamic aggregate crushing value tests (ACVTs). The effect of various compaction loads was also examined by using a Marshall hammer, gyratory compactor and steel roller. Six types of coarse aggregates were tested, including basalt aggregate, steel …

Aggregate Crushing Apparatus a load of 40 ton is applied through a plunger, As shown in fig (2), the material crushed to finer than 236 mm is separated and expressed as a Apply load at a uniform rate so that a total load of 40T is applied in 10 minutes Release the load and remove the material from the …
This test seeks to determine the amount of force required to produce 10% of fine values, which is expressed as the weight of fine aggregates divided by the weight of all aggregates multiplied by 100 (i.e., weight of fines aggregates/weight of all aggregates x 100 = 10%). This test is similar to the Aggregate Crushing Test (ACV), which applies a ...
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 required
