Clay:

The mix design meets the requirements for airport concrete, however the target slump should be 1 - 2 inches for side form construction.

Frank,

Are there any special requirements for concrete on airports?

Thanks,

Clay:

I have attached the concrete mix designs provided by Lattimore Materials Company.
There are two mix designs: one for the apron (5507) and one for the parking lot area (5409).

I have reviewed both mix design, and I am forwarding to you for approval for this project.

I believe that Mix design 5507 for the apron area does meet the requirements for paving as specified in FFA Circular 150/5370-10d Part VI Rigid Pavements (Item P-501 Portland Cement
Concrete Pavement).  Mix 5507 was the same mix design used for the apron area for the previous hangar project to the south.

Do you need hard copies? If so, how many copies do you need?

Thanks
