TL;DR: In this paper, a comparison between the influence of active and inert fine particles on the heat of hydration and the development of compressive strength of blended mortars is made. But the results concern the inert filler and the hydraulic or pozzolanic microfillers, or both.
Abstract: This paper focuses on the comparison between the influence of active and inert fine particles on the heat of hydration and the development of compressive strength of blended mortars. The activity of the mineral additives is assessed by measuring the heat of hydration of the different blended mortars that consist of 90% portland cement and 10% admixture with a 0.45 water-binder ratio. In the early stages, the fine particles accelerate the hydration rate by providing an increased number of nuclei sites for hydrates growth. These results concern the inert filler and the hydraulic or pozzolanic microfillers, or both. At very early stages, the finest particles increase the compressive strength of blended mortars compared with control mortar. Moreover, silica powders, especially silica fume, develop a pozzolanic activity that later increases the compressive strength.
