COMPOSITION OF FIBER AND CEMENT-BASED MATERIAL AND PROCESS OF MANUFACTURING ASBESTOS-BASED PRODUCTS

摘要

A material based on fibres and cement is prepared by incorporating an anionic emulsion of bitumen with slow fracture in a suspension of conventional constituents. The constituents preferably include asbestos or other mineral fibres, cement, organic, especially cellulose-based, fibres and a siliceous filler. A material with improved moisture resistance is obtained.
