Abstract: This paper deals with the optimal design of concrete of mix grade 20N/mm2 . The requirement that makes the selection and proportioning of mix ingredients are The minimum compressive strength required from structural consideration. a. The adequate workability necessary for full compaction with compacting equipment available. b. Maximum water-cement ratio to give adequate durability for particular site conditions. c. Maximum cement content to avoid shrinkage cracking due to temperature cycle in mass concrete. d. The task of concrete mix optimization is to estimate different concrete composition with different composition of aggregate and then to choose the best variants of mix by comparing their economical and mechanical properties as well as durability of the material. Cement with fly ash up to 40% Fine and coarse aggregate with recycled concrete aggregates. Designing a mix with supplementary cementations material to control heat generation. Reclaimed water.
