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