The aggregate crushing value then calculated by dividing the weight passing on 2.36mm sieve with the whole sample weight in cylinder taken for test . datasheet for aggregate crushing value published july 2, 2021 by tsquarecivilengineering.

Aggregate Crushing Value Test – Civil Engineering Total

For this reason, a simple test known as 10 per cent fines value is introduced. when the aggregate crushing value become 30 or higher, the result is likely to be inaccurate, in which case the aggregate should be subjected to 10 per cent fines value test which gives a better picture about the strength of such aggregates.

Number. report the mean as the aggregate impact value, unless the individual results differ by more than 0.15 times the mean value. in this case repeat the test on two further specimens, calculate the median of the four results to the nearest whole number, and report the median as the aggregate impact value. note: the median of four results is.

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. thus the test can be used to assess the suitability of aggregates with reference to the crushing strength for various types of pavement components.

Aggregate Impact Value Test Procedure Civil4m

The aggregate impact test is considered to be an important test to access the suitability of aggregates as regards the toughness for use in pavement construction. it has been found that for majority of aggregates, the aggregate crushing and aggregate impact values are numerically similar within close limits.

Procedure of aggregate impact test. the test sample consists of aggregates sized 10.0 mm 12.5 mm. aggregates may be dried by heating at 100110 c for a period of 4 hours and cooled. (i) sieve the material through 12.5 mm and 10.0mm is sieves. the aggregates passing through 12.5mm sieve and retained on 10.0mm sieve comprises the test material.

Aggregate Crushing Value Test Step By Step Procedure

This test is repeated once or twice and the average crushing value of the aggregate is determined. 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.

Value. in this case repeat the test on two further specimens, calculate the median of the four results to the nearest whole number, and report the median as the aggregate crushing value. note: the median of four results is calculated by excluding the highest and the lowest result and calculating the mean of the two middle results.
