The role of calcium carbonate in cement hydration — The Role of Cement Science in Sustainable Development
Limestone mainly consisting of calcite is a permitted additive to Portland cements often up to a 5 wt limit It is shown by experiment and calculation that much if not all of this calcite is reactive and affects the distribution of lime alumina and sulfate and thereby alters the mineralogy of hydrated cement pastRole of Cement Science in Sustainable Development On the other hand like other mineral additions limestone powder replacing cement can cause a reduction in hydration and strength development rat Appearently the net effect of limestone powder may depend on

Abstract NISTElucidating the Role of the Aluminous Source on Limestone
limestone or quartz cement and their focus has been much more on analyzing calorimetry results and/or compressive strengths than rheology and setting tim In the case of limestone filler it has been suggested that its influence on setting is two fold First it accelerates cement hydrationAug 21 32 Therefore as a means of enhancing AFm phase formation this study elucidates the role of aluminous sources including calcium aluminate cements metakaolin and a hydratable alumina to determine if their addition would enhance limestone reactions and carbonate‐AFm formation in cement
