Northern climates such as Canadian or climates with temperatures dropping below freezing marks, require more attention when working with concrete. Whether pouring concrete, laying blocks & stones or working with cement in temperatures below 4oC, certain procedures must be followed to ensure concrete cures right.
Curing plays one of the most critical roles in developing the strength and the durability of the concrete structure. The process starts taking place immediately after the concrete is poured and the finishing process is complete. The process of curing requires maintaining the moisture as well as the temperature at the desired level. It is critically important not to let concrete freeze during the curing process. These favourable conditions must be maintained at the surface and throughout the concrete to provide enhanced durability and strength. Concrete that has been properly cured contains the right amount of moisture to ensure maximum strength and durability. Pouring and curing of concrete thus plays a vital role.
In winter, it is very difficult to properly cure concrete since the low temperatures tamper with the hydration effect. It is very important to take proper heating measures to successfully cure the poured concrete. This requires expert knowledge about the process, materials and certain guidelines which should be followed to cure the concrete properly during the freezing temperatures of winter.
