Essential for Strength Development & Durability
Proper curing is essential for concrete to achieve its designed strength and durability. Without adequate curing, concrete can lose up to 50% of its potential strength.
Enables cement hydration for maximum strength
Reduces permeability and increases resistance
Minimizes plastic and thermal cracking
Maintains optimal moisture for hydration
Electrical resistance heating used for specialized applications where conventional methods are impractical.
| Cement Type | Minimum Curing Period | Notes |
|---|---|---|
| Ordinary Portland Cement (OPC) | 7 days | Standard condition (27±2°C) |
| Portland Pozzolana Cement (PPC) | 10 days | Slower strength development |
| Portland Slag Cement (PSC) | 10 days | Requires extended curing |
| Hot Weather (>40°C) | 14 days | Increased water loss |
| Vertical/Overhead Surfaces | 10 days minimum | Difficult to cure properly |
Clause 13.5 specifies that concrete shall be kept continuously in a damp or wet condition by ponding or by covering with a layer of sacking, canvas, hessian or similar materials and kept constantly wet for at least seven days from the date of placing concrete in case of OPC and at least 10 days where blended cements are used.
