Significance Of Curing Of Concrete For Durability Of

Curing of concrete plays a major role in developing the microstructure and pore structure of concrete. Curing of concrete means maintaining moisture inside the body of concrete during the early ages and beyond in order to develop the desired properties in terms of strength durability. A good curing practice involves keeping the concrete damp.

3. Warm the subgrade before placing concrete on it during cold weather. 4. Avoid placing a slab directly on polyethylene film or other vapor barriers. Use a 100-mm (4-in.) layer of compactible, drainable fill (not sand). A “crusher run” material, usually graded from 38 mm to 50 mm (1-1 2 in. to 2 in.) down to rock dust, is suitable.
