Evaluation of the Rheological and Durability Performance of Sustainable Self-Compacting Concrete

Self-Compacting Concrete (SCC) is a special concrete that can flow easily across congested reinforcements. Also, it easy to work with and does not segregate. The present investigation aims at the design development of sustainable SCC employment industrial by-products such as Fly Ash (FA), Ground Granulated Blast Furnace Slag (GGBFS), Expanded Perlite Aggregate (EPA). Four mixes were developed attain target strength 30 MPa. Workability tests (slump flow, J-ring, V-funnel tests) performed following EFNARC guidelines ensure fresh properties. Detailed experiments conducted evaluate durability characteristics SCC, water absorption, sorptivity, acid attacks (sulphuric, nitric, sulphate, chloride), Rapid Chloride Penetration Test (RCPT), finally, elevated temperature test. Weight loss, physical observations effects evaluated. study focuses on cost index compares them OPC mixes. From experimental data analysis, was observed showed excellent mechanical properties considerable reduction in cement content. specimens FA EPA exhibit resistance. Following noted reduce about 15–17.2% carbon emissions compared mix.
