Enclosed you will find the necessary submittal documents for the referenced project above for your
review.
Redi-Mix’s strength guarantee per ASTM C94 will not be effective unless the field sampling has been done per ASTM
C172 and ASTM C31 and the laboratory testing fully complies with ASTM C39 and ASTM C1077. Redi-Mix will also

any concrete defects related to the finishing process (cracking, scaling, dusting, delamination, discoloration,
etc.), which is beyond Redi-Mix’s control. This includes proper preparation, compaction and wetting of
subgrade as well as proper spacing and depth of joints and rebar.
During periods of cold weather, all concrete
surfaces should be protected from freezing for at least the first 24 hours after placement to allow the concrete to attain a

purchaser shall then assume all liability for costs associated with rejected concrete due to non-compliant

According to ACI 304.2R Section 4.2.1 “Placing Concrete by Pumping Methods”, the inside diameter of the hose
should be a minimum of 3 times the maximum angular aggregate size of the concrete. (ASTM C33 allows #57LS to
have up to 5% retained on the 1” sieve). It is recommended to minimize or eliminate the free fall of concrete to avoid

pumped concrete, the various boom configurations, length of hose, line reductions and free fall distance are
beyond Redi-Mix’s control and we therefore cannot be responsible for loss of air content or any costs associated
with either rejected fresh concrete or the removal and replacement of hardened concrete due to non-compliant
air content resulting from this or from placing concrete outside of the slump range specified on the mix design.
We thank you for allowing us to submit these documents for your review. Please copy Redi-Mix with the approved
submittal. The approved submittal allows Redi-Mix to review any notes, comments or exceptions made by the engineer
. Failure to notify us prior to first placement shall constitute acceptance of the
or owner relating to the specification
submitted mix designs and submittal provisions.
Please order by mix number when scheduling concrete delivery.
We request that Redi-Mix be added to the list of names receiving copies of testing laboratory information for
this project.
ASTM C94 entitles a manufacturer to receive copies of all test reports when strength of concrete is used
as a basis for acceptance. This information is another tool for Redi-Mix to review and monitor the quality and
performance of the concrete product delivered.
The information within this submittal is confidential and the exclusive property of Redi-Mix. It shall not be
disseminated to third parties without written permission from Redi-Mix Concrete.

This mix has been designed to meet the requirements of this project based on the information sent to Redi-mix Concrete. It is the responsibility of the purchaser to determine whether
this
mix design meets project specifications and is appropriate for the anticipated environment conditions. The specified strength guarantee per ASTM C94 will not be effective unless field
sampling has been done per ASTM C172 and ASTM C31 and the laboratory fully complies with ASTM C39 and ASTM C1077. In the event of limited material avaliability, substitution of a
similar performing material may be required. All substituted materials will meet the appropriate ASTM requirements. In order to maintain the required mix volume, weights of individual
materials may be varied to accommodate different material specific gravities. Material certifications for substituted materials are avaliable upon request.
All Redi-Mix Concrete mix designs are proprietary and confidential. The information contained in this submittal is only intended for parties associated with this project to validate
the mix
design materials, properties and its performance. Use of this submittal for other purposes without permission or consent from Redi-Mix Concrete is strictly prohibited.
