Aggregate Crushing Value Test -Determine Aggregate ...
Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements. Crushing value of aggregates indicates its strength. Lower crushing value is recommended for roads and pavements as it indicates a lower crushed fraction under load and would give a longer service life and a more economical performance.

Abstract Preview 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.
Aggregate Crushing Value - Civil Engineering
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.
Aggregate Crushing Value Test - Procedure and Result ...
Aggregate crushing value provides the resistance of an aggregate sample to crushing under gradually applied compressive load. Generally, the test is conducted on aggregate passing 12.5 mm …
Aggregate Crushing Value Test – Determine Aggregate ...
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 under standardized conditions, and the strength of the aggregate used in road …
CORRELATION BETWEEN AGGREGATE CRUSHING VALUE OF …
ABSTRACT Aggregate Crushing Value (ACV) is an index of loss of coarse aggregate (CA) under sustained loading. However, ACV is not considered in concrete mix design according to ACI 211.1(ACI 211.1, 2009). In this stone effect of ACV of CA on compressive strength of …
RELATIONSHIP BETWEEN AGGREGATE CRUSHING VALUE …
The results obtained show that ACV value for aggregates are 25.04%, 22.70%, 36.13%,and 37.89% for crushed granite, slag , hoggin (all-in aggregate), and river gravel respectively. This show that the ACV test is not favourable in testing weak aggregates as the ACV is more than 30%. for hoggin and river aggregates.
Study on Use of Recycled Aggregates in Pavement ...
Aggregate crushing value is the percentage of the crushed material passing through 2.36mm sieve in terms of original weight of the sample taken. The crushing value of the taken sample was 24.75%. The crushing value of the sample. below 30% and 40%, therefore the recycled aggregate can be used in both the base course and surface course of a pavement.

(BS 812) Scope & significance: Aggregate Impact Value. The aggregate impact value gives a relative measure of the toughness or the resistance of aggregate sudden shock or impact is not proportional to the resistance to a slowly applied compressive load.
A new practical method for determining the LA abrasion ...
The LA abrasion test is the most widely used method for testing aggregate abrasion (Wu et al., 1998). In Australia, the LA abrasion method is available in the Australian Standards (AS 1141.23), whereas other standards, such as ASTM C131/C131M, may be used in other parts of the world.
Theophilus Yisa Tsado ABSTRACT - IJERT Journal
2.2.6 Aggregate Impact and Crushing Values Aggregate impact value gives relative measure of the resistance of an aggregate to sudden shock or impact and aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The aggregates were tested in a surface dry 777
Correlation between Strength and Durability Indices of ...
Aggregate Crushing Value (ACV) ACV is the measurement of relative resistance of aggregate through gradual loading to crushing and can be performed as per the Indian Standard code IS 2386 part IV [11] using compression testing machine.
Properties of Aggregates - Civil Snapshot
The aggregate crushing strength value is a useful factor to know the behavior of aggregates when subjected to compressive loads. Impact Value. The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact. The impact value of an aggregate is sometime used as an alternative to its crushing value.

New testing methodology for the quantification of rock ...
For this purpose, the mineralogical, physical, and mechanical properties of various hard rocks were determined. A new compressive crushing value (CCV) testing methodology was proposed. The results obtained from CCV tests were compared with those from mineralogical inspections, rock strength as well as mechanical aggregate tests.
