This lab experiment aims to determine the aggregate impact value (AIV) of . The impact value is calculated as the percentage of material passing the 2.36mm sieve relative to the total sample weight. A value between 10-20% is considered very strong and suitable for use in concrete and road construction. The results of testing three samples are reported, with an average impact value of 13.42% indicating very strong . The mean of two observations, rounded to nearest whole number is reported as the Aggregate Impact Value. • Aggregate impact value = (W2/W1) x 100 – Where, W1 is total weight of dry sample – W2 is weight of portion passing through 2.36 mm sieve.

• Download as PPT, PDF . Toughness Is the resistance of aggregate to failure by impact. This can be determined by aggregate impact test. The aggregate impact value shall not exceed 45% by weight for aggregate used for concrete other than those used for wearing surfaces and 30% for concrete for wearing surfaces.This characteristic is measured by impact value test. The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. Procedure of Aggregate Impact Test 2. Impact, 10% Fines & Crushing Tests Quarry plant such as crushers, screens, conveyors, etc. are all subject to wear and these crushing tests can indicate the magnitude of the problem for design purposes. PROCEDURE - Aggregate Impact Value (SS 1974) 1. The apparatus consists of a steel test mould with a falling hammer as shown in Figure 1. Here are the recommended Aggregate Impact Test values and their corresponding classifications: Aggregate Impact Value Classification. Less than 20%: Exceptionally strong. Between 10% and 20%: Strong. Between 20% and 30%: Satisfactory for road surfacing. More than 35%: Weak for road surfacing.
The aggregate impact value is expressed as the percentage of the fines formed w.r.t the total weight of the sample Aggregate Impact Value (AIV) = (100*M2)/M1 Where: M1 =Mass of the test specimen M2 = Mass of the test specimen passing 2.36 mm test sieve
