Abstract

This paper presents the framework for a methodology for insuring the durability of construction sealants. The basic approach involves determination of an allowable strain capacity. This is done by establishing a 5% exclusion value on the ultimate strain capacity of the unaged sealant, then modifying that by empirical reduction factors to reflect the effects of service conditions. Fatigue, heat, water, chemicals, cold, and ultraviolet light are considered, as are state of strain, joint geometry, substrate type, and a safety factor. Data taken for tests on a solvent acrylic sealant are used to illustrate application of the method. Further research needs are briefly discussed. © 1982, Taylor & Francis Group, LLC.
