| Title | Methods of Physical Tests for Hydraulic Cement | Specification for Cement for Masonry Work | Specification for Ordinary and Rapid Hardening Portland Cement |
| Scope | Covers all physical testing methods for cement | Focus on masonry cement (for plaster, brickwork) | Applies to Portland cement types |
| Key Tests |
- Fineness - Setting time - Soundness - Compressive strength - Consistency |
- Fineness - Setting time - Tensile & compressive strength - Workability for masonry |
- Fineness - Setting time - Strength - Chemical composition |
| Standard Specimen Size | Cubes: 70.6 mm | Cubes or briquettes | Cubes: 70.7 mm or 50 mm (UK) |
| Setting Time Requirement | Initial: ≥30 min Final: ≤600 min |
As per application usually similar to OPC |
Initial: ≥45 min Final: ≤10 hrs (typically) |
| Compressive Strength | After 3, 7 & 28 days | After 7 & 28 days | After 3 & 28 days |
| Special Notes | Foundation for all cement testing procedures in India | Specially for non-structural cement use | UK standard, now replaced by EN standards |
