With a goal to be able to cast a concrete slab and to dry out the moisture in the concrete in a faster way. To meet the requirement for certification of green building construction, the concrete slab must be dried out to an approved level before it is covered with a flooring material. This sets becomes a problem when today's buildings must be constructed quickly. Normal concrete slabs with 0.55 w/c take several years to dry out to the required levels. In this study we have looked at the parameters of concrete casting and how these affect the drying time. Calculations have been made in software with respect to weather, coverage, depth of water cement number and temperature at casting. Alternative methods have also been investigated such as separating the edge stiffening from the slab. The results show that changing the w/c or pouring with a cold concrete improves the drying process a lot.
