≤ 2 hr
Begin within 2 hours of placement to prevent plastic shrinkage.
// Critical Reminders
- — Maintain continuous moisture, 24/7 — including nights.
- — Use only clean, potable water (never seawater, even on coastal sites).
- — Don't stop curing early; strength plateaus and never recovers.
// Interpretation
What this means
// CRITICAL · Why curing matters more than you think
A perfectly designed M40 concrete that isn't cured properly will deliver only 50–60% of its design strength. Curing is the single biggest factor affecting actual strength achieved on site.
// DO · DO
Start curing within 2 hours of placement. Maintain continuous moisture (not intermittent). Cover with wet hessian + polythene. Cure 24/7 — including nights. Use clean, potable water.
// DON'T · DON'T
Don't allow concrete to dry out at any time. Don't use cold water on hot concrete (thermal shock). Don't stop curing early to save water. Don't allow foot traffic in the first 24 hours.
// Context
When to use this
// What is this
Curing is the process of maintaining moisture and temperature in concrete after placement to allow cement hydration to complete. Hydration creates strength. Without water, hydration stops. Without proper curing, design strength is never achieved.
// When to use it
Use this tool before pouring to plan your curing schedule, water supply, and supplies (hessian, polythene). After pouring, refer to this for daily curing operations.
