چکیده مقاله
Cement mortar, as a cement based material, is one of the core components of concrete, which has asignificant effect on the mechanical properties, such as the compressive strength of concrete Therefore, modifying the properties of cement mortar leads to achieving the highest compressivestrength of concrete In this situation, to achieve these optimal conditions regarding the highestcompressive strength, the conditions of the effective parameters in the mortar matrix must bepresent at their effective levels in the mix design In this research, a laboratory statistical study hasbeen conducted that examines the compressive strength of mortar mixes containing differentcement strength classes CSC of 32 5, 42 5 and 52 5 MPa In this study, 9 mixing designsconsidering three ratios of water to binder materials W/B in the levels 0 4, 0 45 and 0 5 andthree ratios of sand to binder S/B in the levels 2 5, 2 75 and 3 , were made and the laboratoryanalysis and Taguchi's statistical analysis were done The results show that increasing the CSCimproves the compressive strength values of the mortar In addition, the maximum compressivestrength occurs at the CSC of 52 5 MPa, W/B of 0 4, and the S/C of 2 75 As a result, it can beconcluded that the strength classes of cement is a very important and effective parameter andstudies should be considered to make more accurate and acceptable investigations and predictions In addition, the high statistical accuracy and the closeness of the predicted results to the actualresults show that the Taguchi statistical method is considered as a reliable method to optimize andanalyze the effect of the input parameters on the final result
