coarse aggregates, the variation of aggregate crushing value of different coarse aggregates, strength gain of concrete with time for different coarse aggregates and to establish a relation between aggregate crushing value of coarse aggregate and compressive strength of concrete. In the study, Portland Composite Cement (PCC) has not been used.

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


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 …

Effect of Aggregate Properties on the Crushing Strength of ...

This stone studied the effect of aggregate properties on the crushing strength of concrete. In order to achieve the study objective, three types of coarse aggregates, stone khoa, shingles stone, and black stone were used to test. And the test results show that concrete made from black stone has the highest workability followed by shingles stone & stone khoa of aggregates.

Crushing strength of aggregate - Answers

Larger the size of aggregate will decrease strength of the concrete because surface area of this aggregate is low. Lesser the size of the aggregate will lead to increase the strength of the concrete.

Strength of Coarse Aggregates

Strength of coarse aggregates is difficult to measure. While we talk about the strength of coarse aggregates it refers to the crushing strength of the aggregate itself. However, the required information on strength of coarse aggregates can be obtained from indirect tests: crushing strength of prepared rock samples, crushed value of bulk ...

Coarse Aggregate Crushing Strength -

Coarse Aggregate Crushing Strength. Jaw Crusher. The Jaw crusher is used for Primary crushers and Secondary crushers for crushing all kinds of minerals and rocks with compressive strength less than 320 mpa. There are two types of Jaw crusher:coarse jaw crusher and fine jaw crusher.

Influence of Crushed Coarse Aggregates on Properties of ...

different crushing of aggregates same cement and quality of water was used. Fine aggregate (sand), impact crushed coarse aggregate (A-1) and vertically shafted coarse aggregate (A-2) properties were evaluated through lab testing. Source of aggregates, density and porosity (water absorption) of A1 and A2 coarse aggregates were kept constant.

7 Lab Tests on Aggregates to Make Better Concrete for ...

The aggregate crushing value test indicates the strength of aggregate which is the most essential property of coarse aggregate. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. For achieving a high quality of pavement, aggregate of higher crushing strength i.e. low ...

Influence of Crushed Coarse Aggregates on Properties of ...

Both coarse aggregates and fine aggregates are the main constituents of concrete because they not only give the body to the concrete, it also have a significant effect on the fresh concrete based on aggregate’s shape, size, texture, grading and crushing type. Moreover it is proved that aggregate’s types has the severe effect on physic-mechanical properties of concrete as aggregate covered ...
