Franco Massazza, in Lea's Chemistry of Cement and Concrete (Fourth Edition), 1998. Workability. The use of a pozzolanic material whose fineness is similar to that of the Portland cement does not change the workability of mortars very much. Generally, natural pozzolanas slightly decrease the workability of mortar whereas low-carbon fly ashes improve it. 323 High-carbon fly ash can increase the ...
