Fibre cement sheets are composed of fibre cement, and binders. Similar to steel in RCC, fibre is used as reinforcement in these sheets. A fibre cement is a composite material that combines Portland cement, sand, and fibres such as cellulose to enhance durability and strength. In addition to water, fibre cement is hardened. A small amount of chemical additives is also added during this process to enhance the strength. To extract moisture from fibre cement, it is rolled into sheets and compressed. Roofing sheets are then formed for additional impact resistance. The sheets are painted for a highly impressive aesthetic finish.
