limestone and gypsum ratio in cement



ratio of 2:1 of the calcined clay to limestone has been approved, and the amount of gypsum fluctuates between 5 % and 8 % [1-3, 7]. The mixture design of the limestone, calcined clay and cement (LC3) and gypsum are shown in Table 2. The substitutions of LC2 are respectively 60 %, 50 % and 40 % by the mass of the cementitious materials.
