Highly reactive metakaolin has become available as a considerably reactive pozzolanic material in concrete. This type of material is not like other admixtures for example fly ash, blast furnace slag, and silica fumes in terms of production because it is produced from high purity kaolin clay by calcinations at temperatures ranging from 700 to ...
Kaolinite-enriched rocks are generally called kaolin or china clay . This clay encloses a white mineral called dioctahedral phyllosilicate that is formed by chemical changes to aluminum silicate minerals including feldspar . For ceramic applications, kaolin is heat treated and altered into Al 2 O 3.2SiO 2.2H 2 O.

It is found that a mixture consisting of 30% Mutaka kaolin, 15% Mukono ball clay, 30% Mutaka feldspar and 25% Lido beach flint yields a body with highest mechanical strength (72MPa) and dielectric strength (19kV/mm) when fired at 1250°C. The strength (both mechanical and dielectric) is found to decrease with increasing firing temperature. At
The residual strength of clays is affected by their mineral composition and by the nature of their constituent pore fluid. In principle, both factors may influence either strength parameters or stresses, but it is not yet completely clear how this influence works.
