Durable fiber cement materials not only require fewer resources for replacement but help reduce maintenance and repair costs Other Features The raw materials and practices used to create James Hardie products contribute to their sustainability but there are a few more characteristics regarding how the product holds up over time

Competitiveness of the cement and lime sectors Cement production - the majority of EU cement producers operate on a global level giving them access to global best practice and technology Raw materials are extracted mainly onsite which avoids transportation costs and environmental damage

homogenization of raw materials and kiln feed (Aldieb and Ibrahim 2010) Cement is a manufactured product made by blending different raw materials and firing them at a high temperature in order to achieve precise chemical proportions of lime silica alumina and iron in the finished product known as cement

The conservation of natural resources is part of our sustainable business strategy That is why we make greater use of waste materials and by-products from other industries as valuable raw materials and fuels We use alternative raw materials for the production of clinker which is the most important intermediate product in the manufacture of cement In this way we reduce the amount of CO2

Portland cement the kind most often used in concrete is made from a combination of a calcareous material usually limestone and of silica and alumina found as clay or shale in lesser amounts it can also contain iron oxide and magnesia List of material for cement productions
