### Aggregate Impact value Test Apparatus, Procedure and

Jul 01, 2019 The apparatus of the aggregate impact value test consists of: A testing machine weighing 45 to 60 kg and having a metal base with a plane lower surface of not less than 30 cm in diameter. Level and plane concrete floor of minimum 45 cm thickness are used to support it. The base of the machine should also have provisions for fixing its base.

specific gravity value .This test was done by using wire basket. Crushing value test: The crushing value test was carried out by compression testing machine (CTM). The total load of 40 tones was applied at the rate of 4 ton per minute. The percentage crushing value was determined by divided the passing weight from total weight of aggregate.

Clarification: The aggregate impact value is obtained as the ratio of the weight of sample passing 2.36 mm sieve to the weight of the sample taken for the test. For the readings in the question, the aggregate impact value can be found out as =(frac{92}{350}=26.29approx26) % and is expressed as a whole number in percentage. 11.

Feb 13, 2021 In this project, we have carried out certain tests like crushing test, impact test, abrasion test, stripping value test and test for specific gravity on conventional as well as plastic coated aggregates and the results are compared. The tests were performed on 0%, 5%, 5.5%, 6% and 8% of plastic, coated on the aggregates.

Abrasion Test is the measure of aggregate toughness and abrasion resistance such as crushing, degradation and disintegration. This test is suggested by AASHTO T 96 or ASTM C 131: Resistance to Degradation of Small-Size Coarse Aggregate by Abrasion and Impact in Los Angeles Machine. The aggregates are used for the surface course of the highway

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 passing

Get Price; data sheet of crushing strength of coarse aggregate. The aggregate crushing value is a value which indicates the LS-604 Relative Density and Absorption of Coarse Aggregate .

were sieved on 2.26mm sieve. The aggregate impact value is the percentage of fine (passing through the 2.36mm sieve size) to the total weight of the sample. The aggregate impact value should not exceed 30% for use in wearing course of pavements. Maximum permissible values are 35% for bituminous macadam and 40 % for water bound macadam.

Optimization of a Final Crushing Stage The crushers are the last size reduction stage in the value chain. Over crushing is common. The connection between crusher setting and yield is often unknown The rock cannot be repaired. We need to control the crusher carefully.

Jan 20, 2020 Crushing resistance of coarse aggregate is the key to the stability and durability of the skeleton structure of permeable asphalt (PA) mixture. To determine the technical requirements of crushing value of coarse aggregate used in PA mixture, step-loading compression tests were conducted on the mixtures of PA-13 and a control asphalt mixture AC-13, respectively.

[ii] The values presented under each sieve size represent percent passing values. [iii] The asphalt content values represent the mass percentage of the asphalt binder in asphalt mixtures. 3. Test method 3.1. Test method of aggregate 3.1.1. Aggregate crushing value test (RIOH, 2005)

The aggregate crushing value is defined, as a ratio of the weight of fines passing the specified IS sieve to the total weight of the sample expressed as a percentage. The aggregate crushing value is a value which indicates the ability of an aggregate to resist crushing.

Clarification: The aggregate impact value is obtained as the ratio of the weight of sample passing 2.36 mm sieve to the weight of the sample taken for the test. For the readings in the question, the aggregate impact value can be found out as =(frac{92}{350}=26.29approx26) % and is expressed as a whole number in percentage. 11.

The Aggregate Crushing Value offers a related measure of the resistance of an average to crushing under a compressive load that is gradually applied. Drying Shrinkage Drying shrinkage is defined as the contracting of a hardened concrete mixture due to the loss of capillary water.

Jan 20, 2020 Crushing resistance of coarse aggregate is the key to the stability and durability of the skeleton structure of permeable asphalt (PA) mixture. To determine the technical requirements of crushing value of coarse aggregate used in PA mixture, step-loading compression tests were conducted on the mixtures of PA-13 and a control asphalt mixture AC-13, respectively.

The aggregates used for making concrete are normally of the maximum size 80 mm, 40 mm, 20 mm, 10 mm, 4.75 mm, 2.36 mm, 600 micron, 300 micron and 150 micron. The aggregate fraction fro m 80 mm to 4.75 mm are termed as co arse aggregate and those fraction from 4.75 mm to 150 micron are termed as fine aggregate.

The aggregates are used for the surface course of the highway

Therefore aggregate to be used in cement concrete should not be weaker than the strength of hardened cement paste. Determination of Crushing Strength of Aggregate: Material for the standard crushing test should pass through 12.5 mm I.S. sieve and retained on 10 mm I.S. sieve. The aggregate shall be thoroughly sieved on the above sieves before test.

Water absorption values are used to calculate the change in the mass of an aggregate due to water absorbed in the pore spaces within the constituent particles, compared to the dry condition, when it is deemed that the aggregate has been in contact with water long enough to satisfy most of the absorption potential. 5.4.

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
