Why Were Asbestos Fibres Added To Asbestos Cement Roof Sheets

During the production of flat and corrugated asbestos cement sheets used for roofing buildings the asbestos is incorporated into a cement matrix which when kept in good condition limits the spontaneous release of fibres and so these materials do not represent an important source of pollution.

Why were asbestos fibres added to asbestos cement roof sheets.

When exposed to weather and erosion elements such as in roofs the surface corrosion of asbestos cement can be a source of airborne toxic fibres. Since the cement sheets were fireproof manufacturers initially considered them safer as compared to wood. Adding asbestos to the cement made the corrugated roofing sheets more heat resistant weatherproof and durable. In the production of cement sheet thin rigid cement is reinforced using asbestos to form cement sheets.

Asbestos cement is made up of a mixture of cement sand and asbestos fibres for added strength and durability. Further the cement sheet contains asbestos fibres and cement. Corrugated roofing sheets made of asbestos is common in uk homes constructed prior to 2000. Fibro asbestos products are building materials in which asbestos fibres are used to reinforce thin rigid cement sheets.

Asbestos cement products are bonded cement based materials that were heavily used in construction. Asbestos is directly related to a number of life threatening diseases including asbestosis pleural mesothelioma lung and peritoneal mesothelioma abdomen. Nowadays the fibres in cement sheets are typically prepared by using the cellulose it is a material which is found in plants and herbs but it s a fact that in the first ten decades subsequently to fibrous cement sheets were developed they were.
