Apparatus for accelerated weathering of building materials and components
Abstract Natural weathering of building materials and component is a result of the combined influences of a number of aging factors. Climates differ greatly, however, from place to place and from one year to another. Durability consequently depends on time and place. Accelerated artificial weathering is a still more complex matter. When the individual aging factors act in combination, the results can be different from when they act alone. Size and shape of samples are also important. It is desirable to be able to accelerate the individual aging factors to the same extent, but this should not be overemphasized as it is the final result that counts. A special apparatus for accelerated weathering of building materials and components has been designed and built at the Trondheim Branch of the Norwegian Building Research Institute. This equipment is unique as it can take samples up to 1 m2; a striking contrast to those commercially available. The results are promising when compared with practical experiences in Scandinavia. A modified version for samples up to 4 m2 was completed in 1979 and is now running satisfactorily. There seems to be general agreement about the factors that influence the natural weathering or aging of building materials and components. This matter has been dealt with several times before in readily available publications. For this reason, I shall restrict myself to a brief listing of the most important factors.
