N2 - 8 This study followed the reaction kinetics, the evolution of reaction products, and mechanical 9 performance of limestone calcined clay cement (LC 3)-based composites produced with low-10 reactivity kaolinitic clay (LRKC) calcined to 800 o C. It was found that despite pozzolanic 11 reactions, the content of Ca(OH) 2 was increased due to the low reactivity of the calcined clay 12 and an offset by the hydration of WOPC. Without additional hemihydrate, carboaluminates 13 were preferentially formed to ettringite. The addition of hemihydrate led to more formation of 14 ettringite and improved strength development. Also, finer limestone powder enhanced the early 15 strength development as a result of the filler and nucleation effects. 16 17
