SPECIFICATION
The instrument will be used for determining the Aggregate Crushing Value as per IS:2386part 4
i) A 15-cm diameter open-ended steel cylinder, with plunger and base-plate, of the general form and dimensions shown in Fig. 1. The surfaces in contact with the aggregate shall be machined and case-hardened or otherwise treated so as to have a diamond (VI-l) pyramid hardness number of not less than 650 VII.
- A straight metal tamping rod of circular cross-section 16 mm in diameter and 45 to 60 cm long, rounded at one end.
- A balance of capacity 3 kg, readable and accurate to one gram.
- A compression testing machine capable of applying a load of 46 tonnes and which can be operated to give a uniform rate of loading so that the maximum load is reached in 10 minutes. The machine may be used with or without a spherical seating.
- For measuring the sample, cylindrical metal measure of sufficient rigidity to retain its form under rough usage and of the following internal dimensions:
