About 6.5 kg of natural aggregate is required to provide the two test samples. Use less light-weight aggregate. Calculate the percentage of fines generated to the total sample weight. Use the formula: Aggregate Crushing Value = 100(W2/W1) percent where: W2 = Weight of fraction passing the appropriate 2.36 mm sieve. W1 = …

By delving into the details of this test, its apparatus, theory, procedure, and the significance of its results, you can gain a deeper understanding of how to select the …

The observations in the Impact Test are recorded, including the total weight of the dry sample (W1 gm), weight of portion passing the 2.36 mm sieve (W2 gm), and the calculated Aggregate Impact Value in percent. Significance of Aggregate Impact Value. The Aggregate Impact Value is used to classify aggregates based on their suitability for ...

The aggregate crushing value is obtained by the following expression: Aggregate crushing value = (frac{W1}{W2} times 100) W2 = Total weight of the dry sample. W1 = Weight of material passing 2.36 mm I.S. sieve. Additional Information The aggregate crushing value should not be greater than 30% for the surface course and …

which is dependent on the aggregate's impact resistance. This degree is assessed by a sieving test on the impacted specimen and is taken as the aggregate impact value. 7.6.3 Sampling. The sample used for this test shall be taken in accordance with Chapter 2. 7.6.4 Equipment 7.6.4.1 Impact testing machine.

Aggregate impact value is defined as the ability of aggregates to have resistance against shock and impact, toughness. It Also can be defined as the load at which aggregates start cracking due to the impact and shocking. In Impact test of aggregate, the aggregates are tested to find out toughness of aggregate to absorb …

Aggregate demand is an economic measurement of the sum of all final goods and services produced in an economy, expressed as the total amount of money exchanged for those goods and services. Since ...

The aggregate impact value is the ratio of the weight of the fraction passing through 2.36 mm (weight W2) by the total weight of the sample (weight W1 + W2). Aggregate Impact Value = (W2/ (W1+W2)) * 100 = 80 gm / 300 gm = 26.67(Impact Value) Where, W1= Weight of the fraction …

The aggregate impact value gives a relation measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from theirresistance to a slowly applied compressive load. General: Normally the aggregate impact value of base course is 30, bituminous bound macadam is about 35 and the …

Aggregate impact value is then the percentage of fine passing through 2.36 mm sieve to total aggregate weight. Aggregate impact value for different requirement are as follows: ∴ For concreting the surface of the runways, roads and pavements, the aggregate impact value shall not exceed by weight 0.3 and 0.5 for WBM.
