Calculate this mix design. Use the example we used in class. This time, aim for a higher strength concrete mix with a different set of requirements:

Requirements:

Compressive Strength: $4000$ psi $(27\mathrm{.}6$ MPa$)$

Workability: $5-$inch slump

Cement Type: Type II Portland Cement

Aggregates: Crushed stone for coarse aggregate and a mix of coarse and fine sand for fine aggregate

No Admixtures

For this mix, let's use a different mix ratio: $1$:$1\mathrm{.}5$:$2$
