IS 9000 covers cement produced by mini cement plants (up to 200 tonnes/day capacity). Requirements are slightly relaxed compared to IS 269 (OPC) to accommodate smaller plant process limitations, but the cement must still meet minimum quality standards.
Specification covering requirements for cement produced by mini cement plants including chemical and physical requirements, sampling, testing, and marking.
Key Values
28-day compressive strength min22 MPa
Initial setting time min30 minutes
Final setting time max600 minutes
Practical Notes
! Mini cement plant cement has lower strength requirements than IS 269 OPC — check structural design assumptions before using.
! Not recommended for high-strength concrete (M30+) or aggressive exposure conditions.
! Common in rural India where large-plant cement supply chains are weak.
! Always verify 28-day strength test results before accepting bulk deliveries.
