The concrete industry also uses industrial waste byproducts such as fly ash (from coal combustion) and blast furnace slag (created in iron manufacture) to constitute a portion of the cement used in producing concrete. Use of such byproducts in concrete prevents 15 million metric tons a year of these waste materials from entering landfills.

3. PFA is a byproduct, with limited uses. Its major potential uses are as fill, as a raw material in cement manufacture and as a partial replacement for cement in concrete. The direct economic benefits deriving from the use of PFA as fill are small compared with its use as a cement replacement in concrete. 4.

The goal of sustainable construction is to reduce the environmental impact of a constructed facility over its lifetime. Concrete is the main material used in construction in the Gulf Cooperation Council (GCC). Therefore, it makes economic and environmental sense to use recycled materials in the making of new concrete for different applications.

Ceramic products are manufactured at extremely high temperatures between 1000°C1250°C which results in very hard, highly resistant to chemical, freezing and thermal shock. Considering the properties of ceramics their waste such as broken tiles should be included in concrete as a substitute to conventional construction material.
