Using the same materials listed above in Problem $12($along with chemical and mineral admixtures$),$ design a high strength concrete mixture that will be used in a column. The concrete has a specified compressive strength of $14$ ksi at $28$ days. The concrete will not be air entrained. Your design should be in lb$/$yd$3.$ I purposely have not provided the ACI document on developing high strength concrete. Use your knowledge on cement content, water content, supplementary cementitious materials $($mineral admixtures$),$ and water content to develop the mixture.
