Abstract

Asbestos cement sheets used under outdoor condition may need surface treatment because of deterioration. Surface preparation of deteriorated asbestos cement sheets may cause asbestos fibers release during surface preparation. However, technical information about fibers release is not enough to design countermeasures for surface preparation of deteriorated asbestos cement sheets at present. In this study, airborne fibrous particles concentration was measured under several ways of surface preparation of existed deteriorated cement sheets containing asbestos, and asbestos fibers in waste water and dust were also analyzed in order to develop safe surface preparation methods for deteriorated asbestos cement sheets.
