Aggregate Impact value Test Apparatus, Procedure and uses
Procedure of Aggregate Impact value test. The test sample: normally aggregates sized 10.0 mm to 12.5 mm. the aggregates should be dried by heating at 100-110 0C for a period of 4 hours and cooled. Sieve the material through 12.5mm and 10.0 mm IS sieves. The aggregates passing through the 12.5 mm sieve comprise the test material.Non- Thillmethod of test for aggregate impact value may also be equally applied to brick aggregates, 0.3 In the formulation of this standard assistance has been derived from Road Research Monograph No: 5 issued by Central Road Research Institute, New Delhi. 0.4 In reporting the results of a test or analysis made in accordance withIS 5640 (1970): Method of test for determining

Aggregate Impact Test Procedure for Determining AIV as Per
2 天之前Article Name. Aggregate Impact Test Procedure for Determining AIV as Per IS 2386 Part-4. Description. The Aggregate impact test is used to determine the aggregate impact value (AIV), which provides a relative measure of the resistance of a coarse aggregate to sudden shock or impact. Lower Aggregate Impact values indicate Observations and Calculations Calculate the aggregate impact value (AIV) expressed as a percentage to the first decimal place for each test specimen from the following equation: 𝑀2 (𝐴𝐼𝑉) = × 100 𝑀1 Where M 1 is the mass of the test specimen (in g); M 2 is the mass of the material passing the 2.36 mm test sieve (in g).DETERMINATION OF AGGREGATE IMPACT VALUE (AIV) (BS

From the data obtained and the Aggregate Impact Value Test (AIV) that we have done, it shows that our mean value from all three samples is 11.67%. Based from the Aggregate Impact Standard, for the 3.1. Aggregate impact value (AIV) Aggregate impact test was performed on both artificial aggregate and natural aggregate. Table 2 show the test results for the average AIV for each type of aggregates used. From the results, the AIV for the fly ash-based geopolymer artificial aggregate is 22.40% which is higher than the AIV for the bothIOP Conference Series: Earth and Environmental Science
