Devido aos danos ambientais causados pelo processo de fabricação do cimento tradicional, o uso de materiais cimentícios suplementares (MCS) é uma opção para reduzir a emissão de poluentes. Neste contexto, a substituição parcial de clínquer por argilas calcinadas combinadas com calcário (misturas LC3) apresenta-se interessante. Assim, avaliou-se a influência do teor ótimo de sulfatos na produção de seis diferentes propostas de LC3 com caulim flint. Os resultados mostram que a gipsita influenciou na cinética das reações iniciais. O aumento no teor de SO3 acelerou o processo de reação da fase C3S, bem como deslocou o pico de depleção de sulfatos.
