Concrete formwork is usually not insulated and is removed as quickly as possible. By insulating the formwork, however, heat and moisture can remain in the concrete and accelerate the hydration process. Thermal and moisture differentials can be also minimized, reducing tensile strains near the concrete surfaces. This effect of insulated formwork, called the self-annealing process, is discussed in the article along with comparison of the field performance of insulated formwork versus conventional formwork.
