The Percentage Fines is the ratio of the mass of fines formed by the crushing process 221 The percentage fines from these two tests at the maximum load will be used in the following formula to calculate the load required to produce 10 fin 01 03 Aggregate …

The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage, the result being recorded to the first decimal place: Aggregate Crushing Value = (B/A) X 100 where A = weight of oven-dried sample B = weight in 'g' of fraction passing through 2.36 mm IS sieve. 6. Results

Significance of Aggregate Crushing Value Test. The crushing value test is conducted on aggregates that are used for the construction of roads. Lower crushing value aggregates give much more durability for roads due to its lower crushed fraction under the compression load. The road is subjected to motion pressure continuously.

Calculation. The mean percentage fines from the two tests at this load shall be used in the following formula to calculate the load required to give 10% fines. Load …

DETERMINATION OF AGGREGATE CRUSHING VALUE 2.1 Object - This method of test covers the procedure for determining aggregate crushing value of coarse aggregate. NOTE 1 -The 'aggregate crushing value' gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggre-

When the aggregate crushing value is 30 or greater the outcome can be irregular and in those kind of circumstances the ten percent fines value has to be assessed in its place. Apparatus Steel cylinder 15 cm diameter with base plate and plunger

to calculate the load required to produce 10% fines. Force required to produce 10% fines = 14 x X y + 4 where X and y are as above. 3. Reporting of Results 3.1 Calculate the mean of the two results to the nearest 10kN for forces of 100kN or more, or to the nearest 5kN for forces of less than 100kN. Report the mean as the 10% Fines Value, unless the

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, aggregates possessing low aggregate crushing value should be preferred. ... Calculate Aggregate Crushing Value. The ratio of the weight of fines formed to the total sample …

Record the total weight of fines passing through the 2.36mm sieve and calculate the crushing value using the formula: Crushing Value = (Weight of Fines / Weight of Sample) × 100; Calculation. Crushing Value = (Weight of Fines / Weight of Sample) × 100. Note: Weight of Fines is the sum of the weights of aggregates passing through the …

The testing machine then places the measure, with the aggregate in it. An impact load is exerted by releasing a hammer from a known height to strike the aggregate. The impact value is calculated as the resulting percentage of fines generated. Procedure. Collect the aggregate pattern passing via a 12.5 mm sieve and retained on a 10 mm sieve.

This document gives the test method for determination of ten percent fines value (TFV) of aggregates.
