The role of ceramic powder in sustainable thermal-resistant cement-based composites
Original language description
This study investigates the potential of substituting calcium aluminate cement (CAC) with ceramic powder (CP) and reactive alumina (RA) to create thermally resistant and sustainable cement-based composites. A total of 14 mixes were designed with varying admixture ratios up to 60 % of CAC were evaluated, with two ternary systems (A15-C15 and A15-C30) selected for detailed analysis. While CP alone increased porosity and reduced strength, its combination with RA significantly improved performance. The A15-C15 and A15-C30 mixtures achieved compressive strengths of 107.6 MPa and 93.5 MPa, respectively, with reduced porosity and enhanced thermal resistance up to 1400 °C. Calorimetry showed that A15-C15 maintained high hydration activity (280 J/g), while A15-C30 followed an altered hydration path. Phase and thermal analyses revealed altered phase composition with reduced metastable hydrates and calcium aluminosilicate hydrates. Aging confirmed the long-term durability of studied composites.
