“…This substantial improvement in production of cement is accompanied by a rise with in cement sector's absolute energy usage & CO2 emissions. But besides this, this has some huge flaws, but for remarkable qualities of versatility, rigidity, stress redistribution, might have precluded it being used as a material for construction [8][9][10][11][12].…”

High Performance Concrete (HPC) had already gained in popularity throughout the last decade. Concrete strength is not synonymous with HPC. It has multiple criteria apart from strength. That includes the concrete’s elasticity, solidity, longevity & resistance towards certain varieties of assault. Raising structures in a harsh atmosphere really need adoption of HPC. For both the reasonable planning & assessment of a structural concrete, a complete stress-strain curve is important. Concrete buildings constructed in difficult climates, in especially, routine maintenance due to the cost of design and indeed the challenge of replacement. Like a consequence, for efficient planning & restoration, a very well stress-strain graph is recommended. Many research’s had also demonstrated the utility of fibres in strengthening the characteristics of concrete. self compacting concrete(SCC) integrates the capabilities of self compacting concrete in its fresh form with performance improvements in the hardened stage attributable towards the incorporation with fibres. An effort was made throughout this work to explore the stress-strain performance of SCC using quaternary blended self compacting concrete(QBSCC). Relying on the Nan-Su technique, a strength-based mix % of SCC was established & indeed the proportion got quite well employing Okamura’s parameters. Mixes with various admixtures such as fly ash, GGBS, Micro silica were investigated for 0.30 & 0.40 w/b ratios. In this work, incorporating mineral admixtures in SCC mixes to optimal content resulted in a max improvement in ultimate load at early ages of hardened concrete leading towards sustainable development all over the world.
