Abstract: This paper presents the capability of Rayleigh’s dimensional analysis approach to evaluate the compressive strength of cement .The destructive testing of cubes for evaluating compressive strength of cement is associated with the curing of 28 days .The period of 28 days put constraints on field schedules and hence there is a need to develop a mathematical model which can provide the accurate range of results based of previous data . A mathematical model based on Lord Rayleigh’s dimensional analysis approach provides concise and systematic way of evaluating the compressive strength of cement .A functional relationship of variables of cement is expressed in the form of an exponential equation which is dimensionally homogeneous .A dimensional constant is determined from the physical characteristics such as grade of cement ,initial setting time and final setting time and the dimensionless parameters are then formed by grouping together the variables of like parameters .The validation of mathematical model is done with experimental results. The correlation coefficient is developed which indicates the best fitting of model results with experimental results
