Biochar is a high-carbon product produced by the thermal decomposition of organic biomass in an oxygen-free environment. It is mainly used for soil improvement and fertilization purposes, but this study aims to explore the possibility of using biochar as an additional benefit to concrete, which is often used as a material by humans. A literature review revealed several studies in which biochar was successfully used as an additive. The good effect of biochar on the mechanical properties of concrete is based on its nucleation and densification effect, but the internal microstructure, porosity, and chemical composition of biochar mainly depend on the raw material, product, and production type. These tests include investigating the effect of adding different concentrations and amounts of biochar and the cement substitution level on the new product and concrete material, as well as investigating the cement content and the energy balancing potential for the concrete mix.
