Asbestos cement (AC), also known as ‘fibro’ or AC sheet, is a thin cement sheet or panel which is given rigidity by the inclusion of asbestos fibres. Asbestos cement can be moulded into any shape that ordinary wet cement can, but typically, it is formed into flat or corrugated sheets or piping. AC is generally grey or brown in appearance and has a coarse texture.
AC became popular during and post-World War II as a means of building inexpensive structures.
