PREVIOUS STANDARDS

Due to its properties such as strength, durability, affordability, and availability of raw materials, concrete is a popular choice for many building projects. However, the environmental consequences of cement and concrete production can be significant and major environmental loads stem from the sourcing and manufacturing phase in the life cycle, such as sourcing of raw materials, water and energy usage, and release of CO2.

Recent sustainable initiatives are aiming at improving cement and concrete production and composition, and lessen its environmental impact. The GECA standard is seeking to support and reward these efforts to minimise the impacts of cement and concrete products. It enables manufacturers to gain access to credits under green building/infrastructure rating tools and provides assurance for green procurers and specifiers when looking for products with a lower environmental impact.

The Cement, Concrete & Concrete Products (CCCPv1.0i-2017) standard covers three distinct sub categories:

• Cement and supplementary cementitious materials (such as blended cements and alternative non-Portland cements);

• Concrete (including ready-mix and concrete manufactured in temporary batching plants on site); and

• Concrete products (such as masonry, precast concrete, pipes, roof tiles, and autoclaved cellular concrete).
