Understanding Limestone in Cement Concrete Construction

Understanding Limestone in Cement Concrete Construction

Mar 26, 2015 Because the limestone is softer than the clinker it will grind preferentially, resulting in a cement with a better particle size distribution with less energy. The limestone also requires less processing and does not undergo calcination, so it releases less waste in its production. The resulting cement will perform at least as well as cements ...

Nov 01, 2013 When investigating the OPC/limestone, the grinding effect was more pronounced at lower w/p of 0.35 than at higher w/p of 0.50. This was due to the fact that in the lower w/p mixtures, the replacement of cement by limestone allows the remaining cement to hydrate more completely, resulting in a higher degree of hydration.
