This paper monitors the behaviour of compressive strength influenced by variation of water cement ratios and fly ash as partial replacement for cement. The study has express the pressure from this material from water cement ratios and fly ash on the designed mixed for high strength concrete, the study generated various compressive strength base on mixed proportions, this were applied to determine strength development at different mix proportion, such application generated compressive strength values numerically and analytically, this application was applied to compare the strength rate at every twenty four hours and that of seven days interval, the growth rate variation from the water cement ratios was applied to determine the mixed proportion to be applied that will always generate better strength, pending on the level of applied impose loads, furthermore, the study monitor increase rate of fly ash as partial replacement against the percentage dosage of fly ash content, these observed strength at optimum growth were recorded at 25%, variation increase on compressive strength from water cement ratios were between [0.23,0.40 and 0.50] it was observed that water cement ratio of [0.23] obtained the maximum strength compare to [0.40,and 0.50], the study applying modeling and simulation were subjected to model validation, and both parameters developed best fits correlations, the study has express various rate these material can develop strength applying modeling and simulation.
