## 4 Conclusions  
It is an accepted fact that, normally, concrete structures tend to deteriorate rapidly due to adverse conditions such as challenging weather environments. Thus, it leads to costly repairs during their performance span and before their safety and durability limit ends. Thus, to resolve this crucial issue, construction industry employs all useful and highly effective methods and techniques for improving the quality and extending the lifespan of concrete. From all the results analyzed in this study about the performance of concrete with additives as a partial replacement, we find such mixes to be efficient and useable as a replacement of ordinary concrete in construction work. Series of partial replacement from 5% to 25% partial replacement of cement with three materials are studied at room temperature and elevated temperatures up to 500 \({}^{\circ}\)C. It is noted that SF induction in the concrete mix as a replacement effectively improved the base mechanical properties of the concrete. According to this research work, about 20% and 25% SF content serving as the replacement of ordinary cement were concluded to be the optimum quantity for the enhancement and elevation of the compressive and flexural strengths. The workability for fresh concrete (SF based) was at a fine level due to water/cement ratio (w/c = 0.40). The J-ring and V-funnel test results showed that penetration and flow ability for all mixes, especially for MP based mix, are at good levels. The results for the GGBFS based mix of SCC has relatively good compressive, split tensile and flexural strengths as compared to the MP and SF based SCC. It is found that the split tensile strength of sample cylinders increases with incorporation of the waste marble powder at about 25% replacement by the total weight of cement. Any more addition of MP leads to decrease in the Split Tensile strength for sample cylinders. Moreover, upon testing the heated samples of concrete and comparing the results with those of sun-dried samples, we found significant results \begin{table}

Table 9: Variable importance and impact of all strength parameters. showing an elevated level of strength gain by the heated ones. This was due to the increased hydration rate and swift gain of strength by the heated sample under heat. Using ANN, we can clearly visualize that Marble powder comes out to achieve successive results. ANN analysis of SF and GGBFS projects the image of predicted behavior by SCC incorporated with these materials as a replacement part to cement and their impact on three major performance indicators of concrete (i.e., compressive, tensile and flexural strength). Predictive strength of ANN provides help in analyzing and predicting SCC strength by multiple inputs and multiple outputs. The relationship developed shows that up to 25% replacement of cement is feasible to produce the SCC for construction purpose.
