will select the best design for the implementation based on your provided design and testring

results.

Step $1$: Design $($Need to Complete by Thursday $9/26)$

Your group is to design and fabricate concrete cylinders using the materials available in the

construction materials laboratory. Your designed strength should be psi $($Notified by

TA$).$ The materials include: $\frac{3}{8}"$ aggregate, Type I cement, sand, and water, with detailed

properties shown in Table $1.$ For other parameters that are not given, you can make proper

assumptions. You can follow the design procedure we discussed in class to complete the design.

You can propose your own strength. Your design should get an approval by TA before Step $2.$

Table $1$: Properties of Materials Used for Concrete Design

Your final design should be written as $($per cubic yard$)$:

Air content:

$\frac{w}{c}$ ratio:

lb $,$ after adjusted for moisture,

lb

Coarse Aggregate:

b$,$ after adjusted for moisture,

lb

Fine Aggregate:

lb

Cement:

Water:

lb $,$ after adjusted for moisture,

$1$ b

Your batch weight should be adjusted $($we do not batch one cubic yard$).$ We will need abou

cubic feet. Write down your batch weight, and you will use the batch weight in the lab.

Coarse Aggregate:

Fine Aggregate:

Submit your group mix design to TA$.$
