The compressive strength of fly ash concrete and its mineralogy

The use of fly ash as a cement extender in portland cement concrete is well established. Strict requirements are set for the fly ash on its physical properties and chemical composition to ensme its successful application as a partial replacement material for cement. An investigation was undertaken into the effectiveness and properties of a high carbon clinker ash when used as a cement extender at a 30 direct mass to mass substitution for portland cement. The clinker ash came from the Van Eck power station in Windhoek, Namibia and was milled to pass a 63micron sieve. For comparison fly ashes from the Escom power stations of Lethabo, Duvha and Matla were used. Both concrete and pure paste specimens were prepared for the evaluations.
