Testing & QC
Cube Test (IS 516)
// Definition
The standard compressive strength test for concrete. 150 mm cubes are cured in water at 27±2°C and crushed at 7 and 28 days.
Test load rate: 140 kg/cm²/min. Sampling frequency per IS 456: 1 sample per 5 m³ for first 50 m³, then 1 per 50 m³. A sample = 3 cubes.

Compressive Strength
The maximum compressive load a hardened concrete cube or cylinder can withstand before failure. The defining property of structural concrete.
Acceptance Criteria (IS 456)
The statistical criteria in IS 456 Clause 16 for accepting concrete based on cube test results — both individual and group means.
