Abstract

The study has expressed the rate on strength development of concrete as it partially replaced cement with silica fumes, iron slag and Rice husk Ash. Modeling and simulation were adopted to monitor the growth rate of compressive strength, the predictive values that was generated experienced gradual growth rate with slight curve to the optimum level recorded at 28 days of curing. The study monitor the system by improving on the previous work done by other experts, such improvement were carried out by predicting the compressive strength of concrete that partially replaced cement with silica fumes iron slag and Rice husk Ash at the 14 days of curing, while other existing work was carried out on experimental procedure that monitored the compressive within 7 and 28days, there is no literature that has applied this mathematical techniques to monitor the compressive strength analytically, the developed compressive strength generated predictive values that was in agreement with Chaudhary et al. [1] for 7 and 28 days, this generated compressive strength was a model concrete that partially replaced cement with silica fumes, Iron Slag and Rice husk Ash, the predictive model observed silica fumes to attained the optimum compressive strength, followed with iron slag and Rice Husk Ash that experienced the lowest compressive strength, the growth rate of these materials shows that these additives have the highest siliceous content and pozzolanic properties, these study also monitor the system based on the dosage which shows that 5 and 10% experienced the required percentage that developed silica fume as the highest compressive strength. While Iron Slag maintained stable strength above Rice husk Ash which experienced the lowest compressive strength, other concrete properties was monitored to determined there variations influence on the development rates of the concrete model, the model reflected the compressive growth rate on variation of concrete porosities, these were examined from the variation established in the simulation, there rates of influenced monitored were determined in the system, the study is imperative because the behaviour of the model concrete that partially replaced cement in different admixtures has been predicted, there various pressure from other parameters in concrete properties has been examined. Experts will fine these tools as another conceptual technique in developing different concrete model with partial replacement of silica fumes, Iron Slag and Rice husk Ash to attain any designed concrete model.
