VERIFICATION ON ASBESTOS DISPERSAL DURING REPAIR AND REMOVAL OF ASBESTOS CONTAINING COATING MATERIALS FOR TEXTURED FINISHES OF BUILDINGS

Abstract

Asbestos containing coating materials for textured finishes of buildings painted on building walls may cause asbestos fibers release during removal with repair works and demolition works. Curing is necessary for prevention of asbestos dispersal, on the other side technical information about asbestos dispersal is not enough for planning repair and demolition works. In this study, airborne fibrous particles was measured under several removal methods of asbestos containing coating materials from specimen made of concrete and model demolition of specimen with asbestos containing coating materials, and removal methods are compared and verified.
