Low-CO2 technology could replace OPC

A new low-CO2 concrete has been developed through the ECO-BINDER project. The project began in January 2015 and runs for four years. It aims to develop a range of concrete-based construction materials and prefabricated building envelope components with more than 30% lower embodied energy, 20% improved insulation properties and 15% lower cost than the Portland cement-based solutions.

“The project is demonstrating that Ordinary Portland Cement or OPC and OPC-based concrete products based on it can be replaced with new ones based on the Belite-Ye’elimite-Ferrite or BYF class of low-CO2 binders, without compromising on quality or cost,’ says Mr. Frederico Meneghello, Project Coordinator and Technology Intelligence Area Manager at D’Appolonia S.p.A.

The BYF technology offers superior early-age strength and lower CO2 emissions over the lifecycle than OPC. The mix uses has a lower calcium content and a lower clinker burning temperature of 1250 – 1300°C, as well as lower energy consumption for grinding.

To establish a reasonable basis for comparison with Portland cement, ECO-BINDER’s researchers have started by reviewing the regulations and norms in the construction industry to see whether new norms will need to be established, or if it is possible to use existing norms. ‘The ultimate goal is to ensure that a reasonable comparison can be made and that standardisation will not present a barrier to adoption of the new products,” says Mr. Meneghello.

The project includes the construction of small demonstration houses at sites in Spain, the UK and Romania, enabling ECO-BINDER’s researchers to test the impact of climatic conditions.
