Mixing, Placing and Curing Concrete
How Curing Improves Concrete Strength
Description
Curing helps concrete gain strength after it has set. It keeps the concrete moist and at the right temperature so cement hydration can continue. Hydration is the process where cement reacts with water in the water-filled capillary pores and forms the products that fill spaces in the paste.

Transcript
Cement hydration occurs in the water-filled capillary pores of cement paste.
Environmental factors like air temperature, humidity, and wind can cause evaporation, removing water from the surface of newly placed concrete.
Alternatively, if the concrete is sealed and its water-cement ratio is less than 0.5, the internal drying result...
