DRIVING RAIN AGAINST EXTERNAL WALLS OF CONCRETE

SLAGREGN MOT BETONGFASADER

A study has been carried out of the manner in which driving rain gives rise to water run-off on external walls of concrete and of how rainwater of this type is absorbed. The purpose of the study was to provide material for investigations into the mechanisms through which external walls of concrete are solid and into moisture movement in walls of this type. Over a period of more than a year, measurements have been carried out of the quantities of driving rain and water run-off on a number of different external walls. The measurement results have been coordinated with a previous laboratory investigation of the absorption capacity of concrete surfaces which have been subjected to driving rain. The coordinated material comprises a calculation model. The results indicate: that the washing properties of the water are impaired as it runs down the surface of the wall; and that soiling patterns which occur on external concrete walls mainly result from an uneven washing of the walls due to driving rain.
