Analysis of hydration phase of cement pastes with partial replacement of cement by latent hydraulic additives
Original language description
The paper presents a study focused on cement pastes with partial replacement of cement by metakaolin, microsilica and fly ash in different shares: 0%, 10 %, 20 %, and 50 % of cement weight. For all the additives, particle size distribution curves were obtained. Hydration phase of cement pastes was analysed by means of heat flow and hydration heat measurements. The study showed that cement replacement by 10 – 50 % wt. of an additive did not affect the hydration phase qualitatively, but some quantitative differences were found. In general, it can be stated that 20 % or lower cement replacement by any of the tested additives did not affect the hydration process of the cement paste significantly. At 50 % cement replacement, the amount of produced hydration heat and the peak value of heat flow were decreased by approximately 15 % for metakaolin, 20 % for microsilica and 35 % for fly ash.
