A test method for resistance to water immersion is described and the results obtained with two-part polysulfide sealant are presented. Sealant specimens were cast on aluminum and cement-mortar substrates, cured, heat-aged, then enclosed in a plastic

La largeur du joint ne devrait pas être inférieure au minimum requis pour le produit d'étanchéité, compte tenu d' une certaine flexibilité des tolérances de construction et des mouvements cycliques du bâtiment. Les auteurs examinent l'évalua

Joint movements between precast concrete panels were measured on a high-rise building. The movements were correlated to air temperature changes and were statistically evaluated. An experimental coefficient of movement was calculated from the slope of

At the Canadian Division of Building Research in Ottawa the actual movements of expansion joints were charted over a long period on two similar buildings of different heights, one with and one without air conditioning. It was found that joint movemen

This article studies the effects of weathering on one-part chemically curing silicone sealants. The properties of joints exposed to weathering are compared with those of heat- aged, controlled joints by means of tensile tests.

A two-part polysulfide sealant has been exposed on vises in order to subject it to width changes manually: yearly cycles similar to those occurring on a strain-cycling exposure rack that simulates the movement of building joints. The results indicate

Low-movement-capability sealants can be quickly evaluated by using a strain-cycling rack, because failures start to occur within a few months if the material is poor. If failures do not occur within the first winter, then the specimens can last many

The amplitude and the rate of daily joint movement in buildings was estimated from meteorological data. When model specimens of one-part chemically-curing silicone sealants were cycled at these conditions and at various temperatures, the sealant mani

An important factor influencing sealant performance on the outside of buildings is the cyclic movement induced by daily and yearly temperature changes. Although the sealant itself expands and contracts with temperature, these dimensional changes are

A manually operated device has been designed and produced that will enable individual sealant specimens to be subjected to cyclical movements. This simple device can be used in accelerated testing where one of the aging factors is cyclical movements
