Impact of Zeolite and Metakaolin on the Mechanical Properties of Self-Compacting Concrete (SCC)

Applying self-compacting concrete (SCC) in structures with densely packed reinforcement presents a viable solution to address challenges associated with mechanical compaction. This study investigates the impact of varying percentages of zeolite and metakaolin on the hardened properties of SCC. A series of mixed designs were developed and evaluated, focusing on mechanical properties, particularly compressive strength. The findings indicate that incorporating zeolite and metakaolin into SCC, in conjunction with an optimal superplasticizer, mitigates instability issues such as bleeding and segregation. Enhancing the viscosity of mixtures at higher additive percentages while maintaining permeability and flowability within acceptable limits is recommended. Furthermore, the compressive strength of most concrete mixtures demonstrated improvement compared to the control design.
