What is Concrete Blanket?

A Concrete Blanket is a type of protective covering used in construction, particularly in the construction of concrete structures. It is made of a flexible, insulating material, often reinforced with fabric or other durable materials, and designed to be placed over freshly poured concrete to prevent it from freezing, cracking, or drying out too quickly during curing.

Main Function of Concrete Blanket

Concrete blankets provide essential protection for freshly poured concrete. They shield the concrete from environmental elements like freezing temperatures, direct sunlight, and precipitation, which could compromise the curing process. This protection ensures that the concrete maintains the necessary temperature and moisture levels for optimal hydration, improving its strength and durability.

While the main function of concrete blankets is not filtration, they can indirectly support filtration. In cases where water needs to be drained away from the surface of the concrete to prevent pooling, the material of the blanket can act as a filter, allowing moisture to pass through while preventing larger debris from contacting the concrete surface.

Concrete blankets help prevent early-age cracking caused by rapid temperature fluctuations or freezing. By regulating the temperature and moisture, they prevent thermal stress and dehydration, thus ensuring the concrete cures properly.
