Fiber-reinforced cement flat sheets can be used in the construction industry to produce various structural components and products with thin walls, high strength, and complex shapes. The dataset includes primary raw materials, auxiliary materials, energy consumption, and atmospheric emissions from the production process; infrastructure such as production equipment and factory construction is excluded from the system boundary of the dataset. The life cycle inventory is compiled from data obtained from multiple sources. The manufacturing process of fiber-reinforced cement flat sheets includes batching, pulping, slurry storage, refining, slurry release, sheet forming, stacking, demolding, steam curing, drying, edge grinding, and packaging.
