“…Again, clays with only 40% of kaolinite outperforms the other systems [15]. The corrosion of rebars also occurs later than for plain cement, despite a slightly lower chloride threshold for LC 3 [16]. Another durability advantage, is the ability to suppress expansive alkali silica reaction with reactive aggregates.…”

Limestone Calcined Clay Cements (LC 3) permit to continue decreasing the clinker factor in cement. Two widely-available Supplementary Cementitious Materials (SCMs) are used in LC 3 : calcined kaolinitic clays and limestone. The combination of these two SCMs allows additional reactions compared with conventional cements, leading to a high space-filling and excellent properties. Clays with only 40% of kaolinite can be used in LC 3 , providing sufficient strength, higher resistance to chloride ingress and alkali-silica reaction.

“…The study of corrosion of reinforcement in concrete made with LC 3 was also conducted by Pillai et al [ 168 ]. They determined such concrete parameters as chloride diffusion coefficient, ageing coefficient and chloride threshold for seven mixtures containing OPC and blends of OPC with pulverised fuel ash (PFA) or with calcined clay and limestone (i.e., LC 3 ).…”

Calcined clays are the only potential materials available in large quantities to meet the requirements of eco-efficient cement-based materials by reducing the clinker content in blended cements or reducing the cement content in concrete. More than 200 recent research papers on the idea of replacing Portland cement with large amounts of calcined clay are presented and discussed in detail. First, the fundamental information about the properties and structure of clay minerals is described. Then, the process of activation and hydration of clays is discussed, including the methods of pozzolanic activity assessment. Additionally, various testing methods of clays from different worldwide deposits are presented. The application of calcined clay in cement and concrete technology is then introduced. A separate chapter is devoted to lime calcined clay cement. Then an influence of calcined clay on durability of concrete is summarized. Finally, conclusions are formulated.
