Studies on Several Factors Affecting Hydration and Properties of Lime-Pozzolan Cements
Publication: Journal of Materials in Civil Engineering
Volume 13, Issue 6
Abstract
This paper investigates effects of several factors such as lime content and the types of lime on water requirement, initial porosity, strength development, pozzolanic reaction rate, and pozzolanic reaction chemistry of lime-pozzolan cement. The water requirement of the lime-pozzolan cement did not change when lime content increased from 0 to 20% but it increased with higher lime content. A calculation indicated that lime content had a similar effect on the initial porosity of fresh lime-pozzolan cement mortars as on the water requirement. Strength measurement indicated that the optimum lime content for lime-pozzolan cement was around 20%. For a given CaO content, use of quicklime showed a higher lime consumption rate than use of hydrated lime before 28 days but no difference could be observed thereafter. Lime-pozzolan cements made with quicklime gave higher strengths than the cement made with hydrated lime.
