One of the most effective parameters that influence the performance of concrete is the compressive strength of cement. The chemical composition and the physical properties of Portland cement (PC) can be greatly affected the compressive strength of it. So the aim of this study is to make a statistical analysis for the effect of many factors on (3, 7, 28, and 60 day) compressive strength test results. The factors investigated include the main four compounds of cement (C 2 S, C 3 S, C 3 A and C 4 AF) in addition to (CaO, MgO, SO 3 , loss on ignition (LOI), insoluble residue (IR) lime saturation factor (LSF), silica modulus (SM) and alumina ratio (AR)). Furthermore fineness, unsoundness and setting time of cement were also studied. To attain the aim of the present work a statistical program “Statistica” was used for the analysis. It was found that (C 3 S, C 3 A and C 4 AF) compounds has a good correlation with compressive strength, while (C 2 S, CaO, MgO and SO 3 ) has a negative effect especially at age of 3 days, considering that (C 2 S and SO 3 ) effect became positive at 7 day age onward. The effect of (LSF and fineness) was positive on compressive strength and the effect of (LOI, IR, SM, AR, unsoundness, fineness, IST, FST) was negative.
