Develop optimized mixture proportions, including volumetrics, for the selected binder content. Assume $50\%$ CA$1,10\%$ CA$2,$ and $40\%$ FA$,$ by mass of aggregate. Both coarse aggregates have specific gravity of $2\mathrm{.}65$ and absorption of $1\%.$ The fine aggregate has a specific gravity of $2\mathrm{.}62$ and absorption of $0\mathrm{.}8\%.$ The specific gravity of our binder is $1\mathrm{.}017.$
