1092) Experiment of Weathering on Roof with Asbestos-Cement Corrugated Sheets

Environmental health survey in asbestos cement sheets manufacturing industry

About 673 small-scale asbestos mining and milling facilities and 33 large - scale asbestos manufacturing plants, (17 asbestos-cement product manufacturing plants and 16 other than asbestos-cement product plants) are situated in India. The present study reveals the exposure of commercial asbestos (chrysotile) in the occupational as well as ambient air environment of the asbestos-cement (AC) shee...

Mapping of Asbestos Cement Roofs and Their Weathering Status Using Hyperspectral Aerial Images

The aims of this study were: (i) the mapping of asbestos cement roofs in an urban area; and (ii) the development of a spectral index related to the roof weathering status. Aerial images were collected through the Multispectral Infrared and Visible Imaging Spectrometer (MIVIS) sensor, which acquires data in 102 channels from the visible to the thermal infrared spectral range. An image based supe...

Long Term Performance of Asbestos Cement

OBJECTIVE: The overall objective of this research study was to explore the current conditions and state of the art in management of asbestos cement (AC) water main assets and develop a practical, comprehensive guidance manual to be used by the owners of these assets. Issues to be addressed included pipe deterioration and failure, condition assessment, remaining service life prediction, rehabili...

Hyperspectral Discrimination of Asbestos‐Cement Roofing

Asbestos is characterised by a unique set of physical and chemical properties, which has led to its many applications [28], such as roofing coatings: flat and corrugated sheets, floors, water supply pipes, textiles, rope, cord and yarn, paper, friction and composition materials, household products, plastic fillers, clutches, brake linings, gaskets and pads for automobiles [30]. Asbestos‐cement ...
