Control of moisture during construction. Drying of concrete floor; Rakentamisen kosteuden hallinta. Betonilattioiden kuivuminen

Abstract

The drying of various concrete slabs and factors affecting it are studied computationally in the study. The finding of the study indicate that the drying can be significantly influenced by structural means, by controlling the drying conditions, and by the selection of the concrete quality. The drying of slabs-on-ground in a reasonable time requires good drying conditions. The limit values for the drying conditions can be regarded as a minimum temperature of 15 - 20 deg C and a maximum relative humidity of 60 %. The importance of the thickness of the concrete slab is then considerable, and thickness in excess of 80 mm should be avoided. The quality of the concrete has a bearing especially when the drying conditions are poor. As the condition improve, so the significance of the concrete quality declines. In the drying of floors, it is important to know the conditions on both sides of the floor. The temperature difference between each side of the floor has a considerable effect on the drying, and this must be taken into consideration, especially in the drying of face-concrete castings.
