Cement-free concrete is a revolutionary material that aims to reduce the environmental impact of traditional concrete by eliminating cement from the mix. Cement production is a significant contributor to greenhouse gas emissions, so finding alternatives is crucial for sustainable construction.

Instead of cement, cement-free concrete uses other binding agents, often derived from industrial byproducts. Some common approaches include the Alkali-Activated Cementitious Materials (AACM) that activate pozzolanic substances like ground granulated blast-furnace slag (GGBS) and pulverized fly ash (PFA) to create a binding agent.

Other approaches include the steel slag using industrial waste and developing low-CO2 additives that can be mixed with excavation materials to create cement-free concrete.

Last year one of the first companies to use cement-free concrete, a first-of-its-kind innovation in the construction industry, was used in a commercial building project in Seattle.
