Concrete is the most common construction material in the world. Three tons of concrete per year are consumed per capita. Because of its durability, strength and flexibility, it is used in wide variety of structures.
Concrete contains cement, which has a high environmental impact. Cement is the source of approximately 8% of the world´s CO2
One more challenge related to our high consumption of concrete is the enormous use of virgin aggregates.
It also has material waste streams in the form of returned, unused concrete from building sites and waste sludge from the washing of production equipment and trucks.
We need to address these issues and find new ways to produce concrete in a more sustainable way. Linear production models resulting in high consumption of virgin raw materials and waste streams need to be replaced with more circular models. The Mapei RE-CON line offers products and specific solutions to increase the use of recycled raw materials and minimize waste streams.
