Result: Aggregate crushing value = 20%. Result Analysis: The value is higher when more percentage of aggregates crush and break into smaller pieces which indicates the aggregates are of a lower quality. Aggregate crushing value < 45% for aggregates used for concrete for non-wearing surfaces and <25% for wearing surfaces like runways and …
Apparatus needed for the aggregate crushing value test includes a steel cylinder with a diameter of 15 cm, along with a plunger and base plate.

Procedure of Aggregate Crushing Value Test:-. 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.
Objective: 1. Determine of aggregates compression value of coarse aggregate. 2. Evaluate suitability away coarse generators for benefit in other types of roadways. Theory: The " aggregate crush value " give a relative measure of one resistance of

If the aggregate crushing value is 30 or higher' the result may be anomalous and in such cases the ten percent fines value should be determined instead. Aggregate Crushing Value Test The objective of …
View PDF. DETERMINATION OF AGGREGATE IMPACT VALUE (AIV) (BS 812-112) Scope: This Part of BS 812 describes methods for the determination of the aggregate impact value (AIV) which gives a relative measure of the resistance of an aggregate to sudden shock or impact. Principle A test specimen is compacted, in a standardized …

per cent material passing a specified sieve after crushing. The procedure described in SABS Method 842 is followed. Definition The 10 per cent Fines Aggregate Crushing Value is the force in kN required to crush a sample of -13,2+9,5mm aggregate so that 10 per cent of the total test sample will pass a 2, 36 mm sieve. 2 APPARATUS As in SABS ...
This test provides a method for measuring this strength. This method is not suitable for testing aggregates with a crushing value higher than 30, and in this case the ten …

A.3 Preparation of test portions and specimens. ... This document gives the determination of aggregate crushing value (ACV) of aggregates. This gives a relative measure of the resistance of ...
Aggregate Crushing Value is the relative resistance of aggregates to crushing under gradually applied compressive load. 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 …

Also, Read: Laboratory Test on soil – Procedures and Objective. ... Crusher-Run Macadam Base. Max. 30%: IS 2386 Part IV or IS:5640: Also, Read: ...
5.16 The Heavy Impact Value has application to testing the same materials as those tested by the standard, light, medium, and heavy medium heavy impact soil testers, but the greater mass of this impact soil tester provides less sensitivity of the output so is applicable for harder materials at the top end the scales or beyond the ranges of …
When the silt, clay dust, or mud is recent and has not been the resistance by washing, it might generate mini strength concrete [13].The value of aggregate crushing is a comparative measure of a ...
The ACV value is more than 45% for aggregate used for concrete for non- wearing surface and less than 25% for wearing surface like runways and roadways. The higher the aggregate crushing value, the lower the resistance to crushing under the gradually applied compressive load. 5 REFERENCES
The test requires samples of the aggregate to be subjected to standard load crushing conditions. Multiple layers of presieved materials are tamped 25 times before a 40-ton load is applied at a rate of 4 tons per minute. The crushed aggregate is then sieved, weighed, and compared to the original total weight to provide an aggregate crushing ...
of Light compaction values (LCV) with Aggregate crushing values (ACV) and Aggregate Impact Values (AIV). The R 2 values for the relationship was found to be more than 0.9 for both these relationships.
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 weight of aggregate passing the 2.36mm sieve was 560g and the weight of aggregate retained on the 2.36mm sieve was 2220g. The aggregate crushing value that we obtained from the experiment is about 20.1%. We are satisfied with this value since it is lower than the ASTM requirement, which is 35%. Hence, we recommend that this type of ...
getting reproducible results. On the contrary, the aggregate crushing test is simple, rapid and gives fairly consistent results. Application of Aggregate Crushing Test: The aggregate crushing value is an indirect measure of crushing strength of the aggregates. Low aggregate crushing value indicates strong aggregates, as the crushed fraction is low.
The LA value was estimated with the help of some aggregate tests (rock impact hardness-RIHN, coefficient of rock strength-CRS and aggregate crushing value-ACV, etc.) which can be done by using ...
Objective: 1. Determine the aggregate crushing value of coarse aggregate. 2. Assess suitability of coarse aggregates for use in different …
