Resistance of zero-cement concrete to fire

Abstract

<p>Zero-cement concretes are emerging sustainable alternatives to conventional Portland cement concrete due to their potentially lower carbon footprint. With a focus on their fire resistance performance, this chapter reviews the performance of various types of zero-cement concretes at elevated temperatures, including their mechanical behavior, phase transformation, and microstructural alteration upon heating. The outcome highlights the potential of alkali-activated material, calcium aluminate cement, and magnesium phosphate cement as sustainable and fire-resisting alternatives to Portland cement. While more information is needed to investigate the feasibility of using calcium sulfoaluminate cement in fire-prone environments. The presented information will benefit researchers and practitioners involved in developing and applying zero-cement concretes at elevated temperatures.<br></p>
