Pozzolanic activation of metakaolin

Advances in Cement Research, 1992
Metakaolin may be calcined without grinding and suitably activated by Ca(OH)2, Na2SO4, CaSO4 (beta anhydrite) and/or NaOH. The best strengths, 50 MPa from mortar cubes at 18 months, were obtained using Ca(OH)2 and CaSO4 activators. The handling and set properties are similar to those of Portland cement; aluminous C-S-H gel is the best binder.

The measurement of pozzolanic activity

Cement and Concrete Research, 1977
Abstract Some comments are made on the applicability of the hydrofluoric acid method for determining pozzolanic activity. It is pointed out that in addition to silica some other constituents of pozzolanic materials such as pfa are also soluble in HF and the conductance of the solution may, therefore, not be directly relatable to the active silica ...
