AbstractWhen mixed with calcium hydroxide and water, metakaolinite obtained by fixed-bed calcination of a commercial kaolinite at 730°C, hydrates and develops, at 28 days, compressive strengths (tests on minicylinders) of about 10–15 MPa. Hydration products are essentially C2ASH8 and CSH with some quantities of C4AH13. The influence of several factors e.g. curing conditions, value of metakaolinite/calcium hydroxide and water/cement ratios, addition of sand to the mix, which can modify the hardening, has been investigated.
