$3.$ Develop a concrete mixture proportion that has a $28$ day compressive strength of $10,000$ psi. The concrete will be used in an interior column. Use the materials shown in Table $1$ for your concrete mixture plus the supplementary cementitious material shown in Table $2($and the high range water reducers$).$ Use the ACI $211\mathrm{.}4$R$-08$ document to develop the mixture. Do not correct for aggregate moisture. The mixture proportion should be in $$lbs$/$yd$3.$
