Author Description

These 17 papers were presented on June 25 and 26, 2014 at the Sheraton Hotel in Toronto Canada after the regular ASTM C24 meeting. The theme of this symposium was largely inspired by a comment made by a member: “Who cares about durability?” The volume of construction sealants compared to the volume of common construction materials on a major project is extremely small, however the building does not perform properly without sealants. Thus, the short answer to aforementioned question is: everyone should care. The durability of a building is directly related to that building’s sealants. ASTM C24 has global influence on standards for building sealants used in commercial and multi-use buildings. ASTM C24 committee holds the US Technical Action Group (TAG) to ISO TC 59/SC 8 Building Sealants of which both editors are active participants. Developing and developed countries look to the building sealant standards written by the ASTM and ISO groups to accept as their own standards or make modifications from them. This book is the fifth volume concentrating on building sealant durability on an international platform. With the collaboration and dedication of the members of C24 who write and maintain standards, the owners and architects responsible for the world’s iconic structures can be confident of the liquid applied sealant materials that make their buildings safe and comfortable.
