“…In a relatively recent review [144], recommendations were given for the use of calcined clays for ASR mitigation. It was identified that the amount of aluminium and amorphous phase in calcined clay should be quantified before using them for ASR mitigation.…”

“…A great deal of research has been completed on calcined clays due to their availability, low-cost and the simplicity of the manufacturing process. However, there are still uncertainties concerning the viability of the technology as the performance of calcined clays are influenced by mineralogy of the raw materials and carbonation seems to limit the application of calcined clays in concrete (Trümer and Ludwig, 2018). This remains a major barrier to cement manufacturers adopting calcined clays to address the potential shortages of conventional SCMs such as PFA and GGBFS.…”

Low-carbon cements: Potential for low-grade calcined clays to form supplementary cementitious materials

“…The mixes showed low capillary suction, indicating potential pore densification by the SCM, and consequently delaying the time to critical saturation. However, it is important to note that freeze-thaw resistance of clay-bearing composite cements depends on the clay quality (Trümer and Ludwig, 2018). Kaolinitic clay mixes consistently outperform corresponding illitic and montmorillonitic clays with respect to carbonation, chloride diffusivity and freeze-thaw resistance.…”

Limestone ternary cements have attracted significant research and commercial attention recently, for technical and environmental reasons. Standardization of these cements is imminent under BS EN197-5. Presently, detailed understanding of the hydration and microstructure evolution of limestone ternary cements from different alumina-rich supplementary cementitious materials (SCMs) exists in the scientific literature; improved reaction kinetics and additional phase assemblages refine the pore structure. However, understanding of the performance of these cements under exposure conditions is less prevalent. In this contribution, we review these data in a way that allows stakeholders to appreciate the capabilities of the different compositions and their performance. We focus our discussion on critically examining the interplay between the cement composition and the microstructure on durability. It is demonstrated that limestone ternary cements offer a pathway for reducing the embodied CO2 of concrete without compromising their performance. The resistance to chloride ingress, sulphate attack and ASR are significantly improved in a manner similar to binary cements. Carbonation and freeze-thaw resistance is generally lower than OPC but adequate air entrainment can offer improvement in freeze-thaw resistance. The challenge to widespread adoption of these cements is evidence of durability under field conditions. To this end, we recommend large-scale field trialling of these cements and understanding of the role of combined exposures on durability and mechanical properties.
