**1. Introduction to Low-Carbon Concrete**

There is currently a strong effort underway to reduce greenhouse gas emissions and mitigate global warming. To achieve this goal, most industries and human activities must be revised, and a change from the linear approach/model (from cradle to grave) to a circular approach/model (from cradle to cradle) has to take place.

Concrete is probably the most common building material or man-made product, and it was almost entirely produced from virgin materials until recently. Nowadays, the trend is changing, and a more circular approach is being implemented. New types of concrete, such as Low Carbon Concrete (LCC), substitute various materials, primarily waste streams from other industries, for cement. Cement's production has a significant carbon footprint, which also translates to concrete's carbon footprint. The materials that can replace cement are called supplemental cementitious materials (SCM), and the mechanism behind their influence on final concrete properties is described in Section 2.1.
