  • SINTEF REPORT

    2015-8-29 · tons of limestone filler were put directly in the concrete mixer in the ready-mix concrete plants, compared to only 340,000 tons of fly ash. [Bertrandy and Poitevin, 1991] Limestone is often categorized as inert filler, meaning that its influence on cement properties is purely due to its physical nature.

    2021-3-6 · to limestone. Blended cements with 0, 10, 20 and 30 % dolostone filler replacements were prepared and the heat release rate, the flowability and the setting time of the cement pastes with a w/cm ratio of 0.4 were measured. It was found that, the flowability and the setting time, decreased as the filler content increased.
