The effect of limestone chemical porperties and substitution amount on mechanical properties of cement mortar

Using the limestone powder as material that can substitute the clinker, it seems to get positive effect as filler and enhance workability of cement but the substitution amount and chemical properties of it can affect mechanical properties of cement. Thus, in this study, the effect limestone powder that has other properties on cement is evaluated. As a result, the workability enhancing effect was confirmed but deterioration of compressive strength was also checked. Later, with the view of workability, the experiment that the possibility of strength compensation by decreasing unit water weight of limestone powder cement is planned when the limestone powder is used.
