The study define the behaviour of silica fumes and iron slag as partial replacement for cement, the study isto monitor the extend water cement ratios and workability of concrete can influence the growth rate of concrete strength, themodel grade of concrete were designedapplying partial replacement, thesewere adoptedin other to achieved the required target strength, such conditions were applied, but predominant influence were paramount goalthe study want to achieve, this carried outto determined the effect of these stated parameters in the study, modeling techniques were adopted, these concept includes modeling and simulating, these parameter applying this concept is to determine the extent of influence in the study it will also expressed various rate of effect on the growth rate of designed concrete grade, it is observed thatthe surface areaof concrete’s increases, particularly with the addition of fine aggregates, thisalso implies that it has a high demand for water. The study considered these reactions and monitors the extent from the mixed design; the increased in water leads to a higher water-to-cement ratio. Thus monitoring the variation effect of water cement ratios and it workability’s expressed the predominant influence and its variation that was observed on the study. The researchalso expressed high significant rates ofother parameters, this includesvariation ofthe addictive dosage, compaction of concrete, permeabilityand porosity at differentmodel concrete mix,the growth rate from the model concrete to generate the target strength observed initial inner, it remains in that conditiondue to it particle size that is finer than cement. it complement the fines modulus of concrete, thus provide a ball-bearing effect that improves thixotropic behaviour, this influence modify concrete viscosity, while slag expressed it significant on the model concrete as itreduced permeability, improved resistance to chemical attack. The study observed the influenced from these two addictive based on these stated effect on the strength development influenced by the influential parameters, the derived model simulation were compared with experimental values and both parameters expressed best fits correlation, Experts will definitely fine these tools as another conceptual technique in developing different concrete model with partial replacement of silica fumes, Iron Slag to attain any target strength of concrete design.
