RE:

Dear Sir / Madam,

We propose to furnish the following concrete mix for the above referenced project:

Mix Code Number Description Use

Forum Construction

32775

Integra Cove

15733695000 psi in 28 days - Pearock Pumpable

The above mix has been proportioned in accordance with the applicable portions of ACI 211 and your verbal request.

The proposed mix designs will meet the stated strengths when test specimens are manufactured and tested in accordance with current

ASTM standards and evaluated per ACI recommended standards and practices.

Please Note: You must use Mix Code for ordering purposes.

CEMEX requests copies of all approved mix designs prior to jobsite delivery. In order to comply with ACI 318-11 Paragraph

5.3, we request that CEMEX be included on the distribution list for all Concrete Test Reports.

It is suggested that a pre-pour conference be held at the jobsite prior to jobsite delivery. The purpose of the meeting would be to

answer any questions regarding responsibilities in scheduling and jobsite operation.

Please forward this information and data to the proper authorities for approval.

NOTES:

CEMEX has no knowledge or authority regarding where this mix is to be placed. Therefore, it is the responsibility of the project

architect/engineer, and or contractor to ensure that the above designed mix parameters of compressive strength, water cement ratio,

cement content, and air content are appropriate for the anticipated environmental conditions (ie, ACI-318-11 Chapter 4, and the local

Building Codes).

Chemical admixtures are added in accordance with the manufacturers recommendations.

Designed mix cementitious content is stated as a minimum, and CEMEX reserves the right to increase cementitious content. CEMEX

also reserves the right to adjust aggregate weights to maintain design aggregate volumes.

COMMENTS:

* The air content of this mix is entrapped only.

* This mix is not designed to be used as a masonry grout or for use in any type of slab or similar structure which may be subject to drying

shrinkage limits.
