Concrete is everywhere – under your feet on the sidewalk, under your home as the foundation, and in the walls of most skyscrapers. Concrete is the most widely used construction material in the entire world. Rather than existing as an independent material, concrete is a mix of various materials. These materials include cement, water, fine aggregate, and crushed stones or gravel.
Concrete is widely used in residential construction for footings, walls, and slabs on ground. New applications of concrete in 3D printing and hillside foundations are changing the ways housing can be designed and built. In addition, the recipe for concrete is changing – becoming stronger and more sustainable.
Reinventing concrete is key to reinventing the very foundation of how we build our housing.

- Significant changes in how cement and concrete are produced and used are urgently needed to achieve deep cuts in emissions in line with the Paris Agreement on climate change. https://www.chathamhouse.org/publication/making-concrete-change-innovation-low-carbon-cement-and-concrete
- The National Ready Mixed Concrete Association, representing ready mixed concrete producers and those who sell goods and services supporting the industry, are working to make concrete more sustainable. Efforts outlined on their website: https://www.nrmca.org/sustainability/index.asp
- National Concrete Masonry Association – The National Concrete Masonry Association (NCMA) unites, supports, and represents the producers and suppliers of concrete masonry systems – including concrete masonry, manufactured stone veneer, segmental retaining walls, and other hardscape systems. From small family-owned businesses to large corporations, through a collective industry voice, NCMA advances and protects the competitive position of members products, as well as promoting safer and more resilient buildings and communities.

- A group has invented a new way to produce concrete, using a new “Cement Lock” Technology to produce EcoMelt, a cement admixture. Ecomelt a residual of the Superfund clean-up process and is therefore very inexpensive, replacing 40% of the cement currently used to make concrete.
