Q: Why should wet wooden formwork before pouring concrete?
A: Wet wooden formwork before pouring concrete is to prevent the formwork from absorbing the moisture in the concrete, which may affect the molding quality and strength of the concrete. The wooden formwork will absorb the moisture in the concrete, especially when at the beginning of pouring, if the formwork is not fully watered and moistened, it will reduce the fluidity of the concrete, and it may easily harden in a short time, and pitting will appear after the formwork removed.
In addition, fully watered wooden formwork will tight the gaps and it is not easy to leak grout, and able to avoid edges and corners.
