Abstract

The development of rapid-setting cementitious materials is pivotal for modern construction, particularly in precast concrete technology. Calcium sulphoaluminate (CSA) cements have gained attention due to their accelerated hydration kinetics, enabling earlier initial and final setting compared to ordinary Portland cement (OPC). This study investigates the mechanical and chemical behavior of Portland-CSA blended mortars under thermal cycling, addressing the need for durable, high-performance materials in thermally fluctuating environments. CSA cements, characterized by high alumina (Al₂O₃) and sulphoaluminate phases, promote rapid strength development via the formation of ettringite (AFt) and stable hydrates. However, their long-term stability under thermal stress remains underexplored. This research evaluates two CSA types (IRC40, IRC50) blended with OPC, focusing on compressive strength evolution, thermal resistance, and phase composition. By analyzing performance before and after 24 thermal cycles (up to 110°C), the study aims to optimize CSA-OPC synergies for precast applications, balancing economic feasibility with enhanced durability.
