2019年10月18日 the aggregate crushing value (ACV) which gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The method is applicable to aggregates passing a 14.0 mm test sieve and retained on a 10.0 mm test sieve. For other size fractions, there is another recommended method.
2018年11月21日 1.5.2 Test for determination of aggregate crushing value The standard aggregate crushing test is made on aggregate passing a 12.5 mm I.S. Sieve and retained on 10 mm I.S. Sieve. About 6.5 kg material consisting of aggregates passing 12.5 mm and retained on 10 mm sieve is taken. The aggregate in a surface dry condition is filled into
manner as in the aggregate crushing value test in section 2.2.1. It was placed in a cylindrical mould to a depth of 100mm in 3 layer with each layer receiving tamping 25 times from a tamping road.
2017年5月29日 The apparatus of the aggregate crushing value test as per IS: 2386 (Part IV) 1963 consists of: 1) A 15cm diameter open ended steel cylinder with plunger and base plate, of the general form and dimensions as shown in Fig 1. 2) A straight metal tamping rod of circular cross-section 16mm diameter and 45 to 60
2021年5月28日 crushing value. The relationship between the aggregate sizes and the crushing values will however vary with the type of specimens tested. When non-standard sizes of aggregates are used for the crushing test, (i.e. aggregate larger than 12.5 mm or smaller than 10 mm) the size
2019年3月11日 1.The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage, the result being recorded to the first decimal place: Aggregate Crushing Value = (B/A) X 100 where A = weight of oven-dried sample B = weight in 'g' of fraction passing through 2.36 mm IS sieve. 6.Video Aggregate Crushing Value Test
2018年3月13日 The aggregates crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. It is the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load under standardized conditions, and is a numerical index of the
