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
IS9376-1979 1. SCOPE 1.1 This standard covers requirements of the apparatus for measuring aggregate crushing value and ten percent fines value. 1.1.1 Two sizes of apparatus are covered in this standard, one with 150 mm cylindrical cell and the other with 75 mm cylindrical cell. 2.
Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.
between aggregate crushing value ACV and ten percent fines aggregate crushing value TFV for some aggregates in Nigeria. Such a mathematical relationship, usually established through regression modelling on data collected, is useful in saving time and money cost on site through estimating one variable when another is known.
AGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS 2386 Part IV 1963. The apparatus used is Cylindrical measure and plunger, Compression testing machine, IS Sieves of sizes 12.5mm, 10mm and 2.36mm Procedure to determine Aggregate Crushing Value i The aggregates passing through 12.5mm
