Concrete slab on the ground and moisture control : verification of some methods to improve the moisture conditions in the foundation
Författare
Summary, in English
Improved drainage system constitute another type of repair method frequently used for Concrete slabs in the ground with moisture problems originating from the ground. A system of this type was
investigated in a building for two years . The joint water levels close to the drain pipes and below the building were measured every four hours.
Three transient numerical models are presented in the report. All the models can be used to predict temperatures in different parts of mechanically-ventilated foundations. One of the models can also be used to predict moisture conditions in mechanically ventilated foundations.
Superposition and scaling were applied in order to demonstrate a method of determining the temperature-distribution in a ventilated layer on the basis of diagrams and simple manual calculations.
