Abstract
The paper deals with the development of high-performance self-compacting based concrete and optimization of the mix by accounting both mechanical and sustainability characteristics. Taguchi’s L16 orthogonal array is followed to consider 16 concrete mixes in combination of additives as four levels are considered for each additive/factor (class F type of fly ash, colloidal nano silica, crimped steel fiber, and polypropylene fibers). The global warming potential (GWP) is also estimated to account the sustainability parameter. To determine the optimized concrete mix satisfying both performance and sustainability characteristics the normalizing indices are used by accounting: (a) compressive strength and GWP, (b) split tensile strength and GWP, (c) flexural tensile strength and GWP, and (d) compressive strength, split tensile strength, flexural tensile strength and GWP. A detail comparison of normalizing indices is conducted, and the optimized concrete mix is determined based on the average rankings obtained from different normalizing index.
