Procedure of Aggregate Crushing Value Test 1. Put the cylinder in position on the base plate and weigh it (W). 2. Put the sample in 3 layers, each layer being subjected to 25 strokes using the tamping rod. Care being taken in the case of weak materials not to break the particles and weigh it (W1). 3.

The aggregate crushing value provides a relative measure of resistance to crushing under gradually applied compressive load. Lesser the aggregate crushing value stronger is the given sample of aggregates. Object: To determine aggregate crushing value by compressive testing machine. Apparatus required: 1. Steel cylinder open with both ends 2.
crushing strength of aggregate pdf, strength of the aggregate can be a limiting factor to, helps to determine the aggregate crushing value of coarse Read More. CIVL 1101 Shape and texture of coarse aggregates affects the strength of the concrete, These restrictions limit maximum aggregate size to 1 1/2, Crushing-- Soft.
Procedure to determine Aggregate Crushing Value i) The aggregates passing through 12.5mm and retained on 10mm IS Sieve are oven-dried at a temperature of 100 to 110 o C for 3 to 4hrs. ii) The cylinder of the apparatus is filled in 3 layers, each layer tamped with 25 strokes of a tamping rod. iii) The weight of aggregates is measured (Weight 'A').
