Thermally activated brick soils used as SCM in powder concrete
Original language description
Concrete is one of the most widely used materials globally. Its production, particularly cement, is associated with environmental concerns such as high energy consumption and significant carbon emissions. To mitigate this, supplementary cementitious materials (SCM) have been researched extensively. This study explores the potential of using thermally activated brick soils (TABS) as SCMs in concrete. Brick soils, abundant and often considered as a lower quality clay materials, were thermally activated at 650 °C to develop pozzolanic properties. In this research, three types of brick soils (L, B, H) were activated and incorporated into a concrete mix using a rational design approach. The amorphous part of the activated soils replaced cement, while the crystalline part substituted silica aggregate. Key physical and mechanical properties, including compressive strength, porosity, and elasticity, were analyzed. The results showed that TABS significantly improved concrete structure and mechanical properties, demonstrating effective cement replacement up to 25% of the total mix weight. This approach offers a sustainable solution for reducing cement content in concrete production.
