Curing is a concrete treatment effort after the concrete has been cast. Concrete treatment is mandatory because it aims to maintain the humidity and temperature needed for cement to carry out the hydration process perfectly. For this process, nonwoven geotextile is placed on the surface of the newly cast concrete by watering it so that the moisture of the concrete is maintained
To keep the concrete hydration process going perfectly, curing is needed to maintain moisture. The duration of the curing process is around 7 consecutive days starting from the second day after casting.
The objectives of concrete curing are: to ensure the hydration reaction of cement compounds including additives or substitutes so that they can take place optimally so that the expected quality of concrete can be achieved, and to prevent excessive shrinkage in the concrete due to too rapid or non-uniform loss of moisture, so that may cause cracks.
Concrete curing/treatment is carried out immediately after the concrete has experienced or entered the hardening phase (for exposed concrete surfaces) or after the opening of the mold/reference/formwork, for a certain duration intended to ensure the maintenance of the conditions required for the reaction process of the chemical compounds contained in the mixture concrete
Curing can be done in various ways, including:
1. Spraying with a special coating ( such as Vaseline ) on the concrete surface.
2. Wet continuously the surface of the concrete with water. After the curing process, the soil is backfilled layer by layer.
Application: Rigid Pavement cast concrete, cast supporting pillars.
