Fig. 5 The effect on 28 day cement (EN 196 mortar) strengths with additions of fine limestone (c. 1100 m2/kg) to mineralised cement (c. 400 m2/kg) (reproduced from Borgholm et al., 1995) The optimum 28 day strength occurs at c. 2% addition corresponding to the point where all
Portland limestone cement provides advantages for performance and controlled strength of cement and concrete, in addition to lowering production costs and CO 2 emissions. However, it is important to use the right cement additive with the right amount of limestone in order to achieve these benefits.
reflect the effects of weathered cement clinker, with high values indicating prehydration of the cement clinker. However, limestone additions also increase loss on ignition, and this increase may mask the effect of prehydration. Cement manufacturers agree that limestone additions will increase loss on ignition. But because the lossonignition

Jun 02, 2014· The use of limestone in the cement can slightly decrease bleeding based on its fineness but generally does not have an effect. Set Time. Based on studies, it appears that cements with limestone may have a slight effect on setting time; however, this should not constitute a concern for the addition rates of 15% or less.
