Sheets made from fibres, Portland cement and binders are called fibre cement sheets. As in RCC, fibres are used to reinforce these sheets. These sheets are manufactured to exceed the strength specifications in the relevant Indian standards. Fibre cement sheets are widely used in a variety of applications because of their unique advantages and properties. Most often, they are found on the roofs and walls of agricultural and industrial buildings. The sheets may also be used in smaller structures like sheds and garages because of their wide variety of sizes.
