• Understanding Limestone in Cement, Concrete Construction

    Mar 26, 2015· The limestone acts as a seed crystal for the cement, better distributing the reaction products and increasing the reactivity of the cement. As there is always unhydrated cement in the concrete, this change will have no real measurable effect on the use of fly ash. The cement might have a reduced water demand, and the coarser cement gradation will likely improve the efficiency of water

  • The role of limestone and calcined clay on the rheological

    Mar 01, 2020· This renders limestone calcined clay cement (LC3) a viable alternative for the future of green cement. One of the main differences between LC3 and OPC is rheological behavior, which greatly influences practical application. Rheology plays a key role in the application of cementitious materials and in achieving successful concrete performance.
