Abstract: The aim of the present study is to develop the concrete by using the industrial waste and assessing the fresh & hardened properties of concrete. In this work, the materials used in the concrete are fly ash, ground granulated blast furnace slag (GGBS) as fully replacement of cement. Self Compacting Geopolymer Concrete (SCGPC) is considered as modern construction material in concrete technology. As the name replies, it does not need any compaction efforts, to achieve full compaction and utilizes Supplementary Cementitious Materials (SCM) in addition with alkaline solutions like sodium hydroxide and sodium silicate and super plasticizer as a binder for matrix formation and strength. In the present study, fly ash based SCGPC replaced with various percentages of GGBS was developed. The concrete specimens were cured both oven curing and ambient curing. For assessing the workability properties – Slump Cone test, V – Funnel test and L – Box test were carried out as per EFNARC guidelines and for assessing the strength properties – Compressive strength test, Flexural strength test and Split tensile test were conducted. The results indicated that with the addition of GGBS by replacing fly ash in SCGPC, the workability characteristics are decreased and strength was increased with the increase in GGBS content. The results also indicated that the SCGPC was suitable for use at both oven and ambient temperature curing. The durability tests were conducted on specimens and found that the durability increases with the increase of GGBS content.
