Feb 08, 2012 The aggregate impact value (AIV) is B AIV = 100 (%) . . . (1) ARESULTSAn average is taken of the two tests and the result is recorded to the nearestwhole number as the Aggregate Impact Value.The AIV is normally about 105 per cent of the Aggregate Crushing Value and itcan be used for the same purpose. For weak aggregates, the required load

Sep 12, 2015 Impact Test Fig-3 Impact Test Setup. The aggregate impact test is carried out to evaluate the resistance to impact of aggregates. Aggregates passing 12.5 mm sieve and retained on 10 mm sieve is filled in a cylindrical steel cup of internal dia 10.2 mm and depth 5 cm which is attached to a metal base of impact testing machine

The impact value test is hence used to determine the measure of the toughness of aggregates. 2. General Test Procedure of Impact Test of Aggregate The general test procedure of the aggregate impact value test is briefly described below: Objectives of Impact Test. 1. To assess the suitability of the aggregate to be used in the highway pavement. 2

May 17, 2019 Procedure The aggregate sample: The material for the standard test consists of aggregates sized 10.0 mm to 12.5 mm.The aggregates must be in a surface dry condition before testing. The aggregates may be dried by heating at 100 oC – 110 o C for not more than 4 hours and cooled to room temperature before testing, if necessary

such as impact, crushing and abrasion resistance be used to assess aggregate durability. The Micro-Deval abrasion test was developed in France during the 1960's. It is a wet ball mill test. A 1.5 kg graded aggregate sample (retained on the 9.5 mm sieve), 2 L of water and a 5 kg charge of 5 mm diameter steel balls are placed in a stainless steel

Aggregate Crushing Value and Its Test Procedure: One of the test in which concrete material can fail is due to crushing under compressive stress. Aggregate crushing test is standardized by IS: 2386 part-IV and used to verify the crushing strength of aggregates. The aggregates should be oven dried, which can passes through 12.5mm and retained on
