Aggregate Crushing Value Test – Determine

17/05/2019  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 construction is expressed by numerical index.

Aggregate Crushing Value Test -Determine

05/05/2010  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.

Aggregate Crushing Value Test - Significance Test ...

Calculation of Aggregate Crushing Value. The crushing value of aggregates is measured in the ratio between the crushed aggregates, obtained from the IS sieve 2.36mm and the weight of the dried aggregate sample. At least three samples should be tested from the same batch and average value to get accurate results. The crushing value of aggregate = (W2/W1) x 100. Lab Report

Aggregate crushing value test Step by Step

The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember. It is recommended that the crushing value of aggregate should be less than 30%. If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is less than 30% can be used for cement concrete road. The aggregate whose crushing value

How to determine the crushing value of aggregate?

The aggregate crushing value= B/A*100 . Where, B is weight of fraction passing 2.36mm sieve ; A is weight of surface dry sample taken in mould. Note. The aggregate crushing value should not be more than 45% for aggregate used for concrete other than the wearing surfaces. 30% for concrete used the surfaces such as runway, roads and air field pavements.
