Comprehensive guidance on testing concrete properties |
Specimen preparation and curing |
Surface preparation for compressive testing |
| Sample Types |
Cubes, cylinders, beams |
Cubes, cylinders, cores |
Cylinders |
Cylinders |
| Curing Conditions |
Submerged in water at 27 ± 2°C for 28 days |
Water curing or moist storage |
Moisture-retaining wrapping or water tank at 23 ± 2°C |
Not applicable (focuses on surface preparation) |
| Specimen Size |
Cube: 150 mm; Cylinder: 150×300 mm; Beam: 100×100×500 mm |
Cylinder and cube sizes vary based on test |
Cylinder: typically 150×300 mm |
Specimen ends prepared for uniform load distribution |
| Testing Ages |
7, 14, and 28 days |
7 and 28 days (usually) |
As per project specification, typically 7 and 28 days |
Before compressive testing |
| Remarks |
Widely used in India for strength evaluation |
Standard in UK-based projects |
Focus on handling and initial curing |
Ensures accuracy in compressive strength testing |
