Early-strength development of portland cement mortars containing air classified fly ashes
A study of the effect of different fly ash sized fractions on compressive and flexural strength of blended cement mortar is presented. Mortars containing fly ashes, replacing 15 % to 60 % of Portland cement, were prepared, and compressive and flexural strengths compared with 'only cement' mortar. The influence of curing temperature was also studied. The study reveals that: a) compressive and flexural strength for mortars containing fly ash (or their sized fractions) are significantly enhanced when curing temperature is raised; b) the content of fly ash finest particles (less than 10 microns) is a crucial parameter for yielding a compressive strength enhancement; c) good correlations between strengths and particle mean diameters were observed when fly ash percentage of substitution was 60 %.
