The cold crushing strength (CCS) and cold modulus of rupture tests are described by ASTM Method C133. In the cold crushing strength test, a sample 41/2" x 41/2" x 21/2" or 3" is loaded at a standard rate using a suitable mechanical testing machine. The load is applied vertically to the 41/2" x 41/2" face of the sample until failure ...

Cold crushing strength is often refer to as compressive strength (Adeleke et al. 2019b) and it represents the maximum crushing load a briquette can withstand before cracking or breaking. The CCS ranged from 2.02 to 4.00 MPa for those cured at 300 °C for 60 min and 0.86 to 3.27 MPa for briquettes cured at 300 °C for 120 min.
