Aug 08 2020 Fresh and hardened properties of newly developed mix were evaluated. Life-cycle cost analysis LCCA was also performed to evaluate the efficacy of the developed concrete using RFA. The result shows that the developed mix design uses lesser quantities of cement and fine aggregates. Replacement of about 30 river sand RS by RFA was found optimum.
