Due $10/2/24$

A concrete mix for a concrete beam exposed to mild climate is to be designed according to the

ACI Absolute Volume Method. A non$-$air$-$entrained concrete is to be used. The specified $28-$

day compressive strength $(f^{\text{'}}c)$ is $4,500.$ The standard deviation of the compressive strength

of the concrete is known to be $360$ psi $.$ The specified slump of the fresh concrete is $3$ to $4$

inches. The cement used will be a Type I cement. Use the following properties of the

aggregates:

Please show your calculation steps clearly. Please give a mix summary showing the weights

of all the individual mix ingredients per cubic yard of concrete. Please also show the unit

weight of the designed concrete. Please write or type out your solution clearly. Please

submit the finished homework in class on either $\frac{9}{30}$ or $\frac{10}{2}\frac{?}{24}.$
