17-04-2021  The cement manufacturing process consists of the following steps: Grinding and mixing of the raw materials. Burning of the mixture at a specified temperature for the correct duration. Grinding the consumed item called (clinker) along with gypsum.

How is fiber cement board manufacture

Fiber cement board manufacturing process also makes use of autoclave technology. In autoclave technology, polymer based composites are manufactured by applying intense heat and pressure to eliminate moisture from fibre cement materials. This leads to composite consolidation and the result is an extremely strong and robust fibre composite material.

Environmental impact of concrete - Wikipedia

The environmental impact of concrete, its manufacture and applications, are complex. Some effects are harmful; others welcome. Many depend on circumstances. A major component of concrete is cement, which has its own environmental and social impacts and contributes largely to those of concrete. The cement industry is one of the main producers of carbon dioxide, a potent greenhouse gas.
