Two metakaolins, with similar mineralogical composition but which vary in their surface area (11.1 versus 25.4 m2 ∕g ), were evaluated for use as supplementary cementitious materials through measurements of workability, setting time, strength, elastic modulus, heat evolution, calcium hydroxide (CH)...
