摘要：

The present study emphasizes the potential use of Argon Oxygen Decarburization (AOD) steel slag in concrete production. Five mixes along with the control mix were made by partially replacing cement with AOD steel slag varying from 10%, 15%, 20%, and 25%. The different properties of all the concrete mixes were evaluated by assessing slump, compressive strength, flexural strength and other durability properties. The air permeability index and sorptivity index showed positive results with an increased percentage of AOD steel slag in the mixes. From the study, it is concluded that AOD steel slag can easily be replaced by cement in the construction of rigid pavements. Further, we have also constructed a Feed-Forward Neural Network (FFNN) to predict the compressive and the flexural strengths of steel slag mixed cement concrete for pavements.
