This study is an effort towards modeling of Self-Compacting Concrete (SCC) using the experimental data's obtained from compressive strength test. Silica Fume (SF) was used as a partial replacement of cement. The influence of Silica fume as a mineral admixture of Self-Compacting Concrete was studied. A three level three factors plan was used in the experimental work. The three levels are bottom (−1), mean(0), upper (+1). The three factors are water-binder ratio (X1), binder content (X2), SF portion in binder (X3). With that three factors, factorial plan was made. Concrete samples were casted for 15 kinds of mixes and tested for its 28 days compressive strength. From the experimental data, using polynomial regression, three equations were derived. First equation describing about the dosage for the chemical admixture, second equation is for compressive strength and third equation gives the mineral admixture efficiency. These polynomial equations also describing the influence of water-binder ratio. The values of experimental and calculated values from equations were compared and best mix has been found.
