10. Fresh Concrete – Curing Methods
Curing is vital for concrete as it influences strength, durability, and resistance to environmental factors. The chapter discusses the objectives of curing, factors affecting it, various methods including water curing, membrane curing, and innovations like self-curing concrete. It emphasizes the importance of proper curing duration and the consequences of inadequate curing practices.

What we have learnt
- Curing maintains moisture for concrete hydration, controls temperature, and prevents cracks.
- Different curing methods are suited for various environmental conditions and types of concrete.
- Inadequate curing can significantly reduce concrete strength and durability.
Key Concepts
- -- Curing
- The process of maintaining moisture and temperature in concrete post-placement to ensure complete hydration.
- -- Moist Curing
- The most effective curing method involving continuous water supply, such as ponding or spraying.
- -- Membrane Curing
- A method using compounds to form a membrane that minimizes moisture loss when water is scarce.
- -- SelfCuring Concrete
- Concrete that uses internal curing agents to retain moisture and support hydration without external water.
