Clinker substitution by a combining multiple supplementary cementitious materials has been established as the most promising solution for combating the greenhouse gas emissions from the cement industry. Limestone calcined clay cement is a ternary cement in which clinker is partially replaced using calcined clay and limestone. This paper discusses the importance of using low-grade kaolinite clay for producing limestone calcined clay cements. While it appears that higher grade clay would be more beneficial at higher substitution levels, it is seen that the availability of portlandite becomes the limiting factor in LC3 cements having low clinker factors. Additionally, the reduction in the long-term clinker hydration, which has been reported in LC3 systems, is not observed in the presence of low-grade kaolinite clay. |
