The effect of natural pozzolan on delayed ettringite formation of the heat-cured mortars

•The use of finer pozzolan in partial replacement of cement controlled or even eliminated the DEF expansion.•The substitution of cement with coarse pozzolan is not only ineffective but even accelerated the DEF expansion.•The DEF was correlated with the evolution of the mass, compressive strength, el...
