## 1 Introduction  
After the production of self-compacting concrete in the 1980s, it has become a very widely used type of concrete, which is highly able to penetrate the closely spaced steel bars without any compaction procedures. SCC differs from normal concrete as it is at a higher end in workability and the issues of segregation and bleeding are encountered in these types of concrete [1]. Nowadays, it is widely used in many developing countries for versatile applications, high rise skyscrapers, urban infrastructure and structural configurations. Use of SCC develops substantial advantages for the productivity of the construction work. The growing trend of utilizing waste materials and industrial byproducts in the production of useful entities is being practiced all over the world. Using materials that are nearly useless for any advantageous purpose to effectively increase the strength of concrete is an efficient way to counter the hazardous effects of such materials. By using different percentages of materials as replacement for cement in concrete mix of grade M20 (Mix ratio 1:1.5:3) and a suitable water-cement (w/c) ratio 0.40, there is a broad analysis of performance of such high strength concrete with respect to the different adding ratios by testing the mechanical properties of concrete such as its compressive strength, split tensile strength and flexural strength [2]. Fresh properties for the SCC have also been monitored and examined, including the V-Funnel test, J-Ring test and Slump test. All these were carried out for the detail examination of fresh concrete behavior. Tests for hardened concrete were carried out using samples of different ratios of materials as a replacement in hardened cylinder and cube form. Many samples were casted for the comprehensive testing process. The samples with replacement ratios of 5%, 10%, 15%, 20% and 25% are tested thoroughly to analyze the hardened properties of mixes. By the utilization of these industrial byproducts and waste materials, an elevated level of pollution treatment can be achieved by the construction industry all over the world. This induction of materials in concrete tends to provide efficient and high strength ranging concrete mixes and is eco-friendly, too [3]. Previously much discussion was had on replacement of cement with Fly Ash and Marble Powder [4; 5; 6; 7; 8; 9], but Ground Granulated Blast Furnace Slag (GGBFS) [4] was limited in use. Therefore, this research has contributed the comparison of Fly Ash and Marble powder with GGBFS not only at room temperature but also at elevated temperature. Furthermore, most previous studies only major focused on compressive strength [4; 5; 6; 8; 10; 11; 12; 13]. However, in this research tensile and flexural strength has also been studied. Self-compacted concrete (SCC) is one of the famous types of concrete but addition of industrial waste additives to partially replace the cement and treating concrete at elevated temperature in SCC has been proposed for the first time in this study. Performance of concrete in normal environment and elevated temperature gives a comparative analysis. The property of concrete to sustain in elevated temperature environments provides an opportunity to test its behavior during fire in structures. Employment of such wastes and their beneficial effects for structures are observed in this study.  
Although Artificial Neural Network (ANN) is famous in predicting Compressive strength of self-compacting concrete (SCC) [14; 15; 16; 17], in this study, new variables have been tested, which are basically related to change of additives, curing conditions, change of type of additive and percentage of additives. Taking advantage of prediction with multiple inputs and multiple outputs, compression, tensile and flexural Strength have been predicted through ANN.
