Conclusion. The above results suggest that using coarse sand (Sand 1) in lime mortar gives better results (approximately 50% increase in comprehensive strength) than using fine sand (Sand 2). This suggests that for practical reasons coarse sand should be used to improve carbonation and eventually compressive and tensile splitting strength.
