PRODUCT USE
QUIKRETE

Q•MAX PRO Concrete Mix is suitable for any concrete
use requiring high early strength and rapid strength gains. QUIKRETE

Q•MAX PRO can be used for any structural application requiring
concrete in a minimum thickness of 1-1/2in (38mm), such as slabs,
footings, steps, columns, walls, floors, ramps, sidewalks and patios.
SIZES
• QUIKRETE

Q•MAX PRO Concrete Mix – 80-lb (36.2 kg) bags
YIELD
• Each 80-lb (36.2kg) bag yields 0.6 cubic feet (16.9L). Yields will vary
based upon waste, uneven sub-grade, etc.

INSTALLATION
SITE PREPARATION
Stake out the area and remove sod or soil to the desired depth. Nail
and stake forms securely in place. Tamp the sub-base until firm.
MIXING
• WEAR IMPERVIOUS GLOVES, such as nitrile when handling
product.
MACHINE MIXING
• QUIKRETE

Q•MAX PRO can be mixed in a barrel-type concrete
mixer or a mortar mixer. Choose the mixer size most appropriate for the
job size. Allow at least 1-cu ft (28.3L) of mixer capacity for each 80-lb
(36.2kg) bag of QUIKRETE
®
Q•MAX PRO to be mixed.
• For each 80-lb (36.2kg) bag of QUIKRETE
®
Q•MAX PRO to be mixed,
add approximately 3-qt (2.8L) of fresh water to the mixer. Turn on the
mixer and begin adding the bags of concrete to the mixer.
• If the material becomes too difficult to mix, add additional water until a
workable mix is obtained.
• If a slump cone is available, adjust water to achieve a 3-in to 5-in
(75mm to 125mm) slump.
HAND MIXING
• Add approximately 3-qt (2.8L) of clean water into a suitable mixing
container for each 80-lb (36.2kg) bag to be mixed.
• Empty bags into the container.
• Work the mix with a shovel, rake or hoe and add water as needed until
a stiff, moldable consistency is achieved.
PRODUCT DESCRIPTION
QUIKRETE

Q•MAX PRO Concrete Mix provides 1 hour of working time; a walk-on time of 3
hours; and achieves 6500-PSI (44.8MPa) in compressive strength. It is a commercial grade
blend of gravel, sand, fast setting cement, and other proprietary ingredients specially
designed for extended working time, high early strength and fast project completion.
QUIKRETE

Q•MAX PRO Concrete Mix is alkali-resistant fiber glass reinforced for crack
resistance and includes an air-entraining admixture for superior workability and freeze-thaw
durability. Corrosion protection is built into the design.
