Abstract:
Three natural pozzolans, a fly ash, and a sample of silica fume have been characterized by means of chemical analysis and nitrogen adsorption. lanic activity i.e. the The pozzo-lime consuming capacity of each of these pozzolans has been evaluated by making portland cement - pozzolan paste and determining free calcium I : hydroxide contents after different intervals of hydration. Mechanical strengths of the above portland cement -pozzolan mixtures have also been determined. The results indicate why previous workers in this area have obtained discordant results.
