When finely ground limestone is added to cement, it reacts with water to form calcium silicate hydrates, which contribute to the strength [[34], [35], [36]], and durability of concrete [36,37]. The blending of LS, calcined clay, and clinker will form LC3 known as ternary cement which is widely available to reduce clinker content [38].
