Utilization of ceramic powder, calcined shale and sintered mullite as partial replacements of calcium aluminate cement

Popis výsledku v původním jazyce

Supplementary cementitious materials (SCMs) are widely used with Portland cement. Similar approach was applied for calcium aluminium cement in this paper. Potential SCMs were ceramic powder, calcined shale and sintered mullite. Cement pastes with 5% or 15% of SCM were prepared and their phase compositions and basic physical and mechanical properties were studied. The analysed blended cements showed an advantageous performance not only at the ambient temperature, but also after high-temperature exposure up to 1400 °C. Ceramic powder had the most significant impact on the hydration process. Calcined shale caused a higher hydration degree, sintered mullite primarily affected the formed C-A-S-H phases.
