Cementless eco-concrete

In Canada, they came up with cementless eco-concrete from waste. The new material is 30% stronger than the classic counterpart. The manufacturer uses steel slag and carbon dioxide from the surrounding air instead of cement. As a result of their contact, calcium carbonates are formed. The pilot project provides for the production of 450 tons of concrete per day, which is 25,000 bricks. With such volumes, the new technology will allow capturing about 20 tons of carbon dioxide per day.
