5000 CONCRETE MIX
 ProMasonry 5000 Concrete Mix is a high-early strength concrete mix
with a 28-day compressive strength of 5000 psi.
All ProMasonry products are processed through precision blending equipment
to ensure a consistent product of superior quality.
SUGGESTED USES
Footings, foundations, steps, sidewalks,
post holes, patios, floor slabs or any general
concrete applications where a thickness
greater than 2 inches (50 mm) is required.
PREPARATION
Compact and moisten the base material.
Place forms and reinforcing steel as needed.
When repairing concrete, remove all
loose and/or deteriorated material
as well as any surface contaminants such as
oil, paint, grease, etc.
MIXING
Empty the contents of the bag
into a clean wheelbarrow, mortar box,
mechanical mixer or other mixing vessel.
Form a crater with a shovel or hoe
in the center of the dry mix.
Pour the recommended 3.6 quarts (3.4 L)
of clean potable water into the crater.
Caution
An excessive amount of water
will weaken the mix and can result in
cracking. Add small quantities, 1 pint (0.5 L)
or less, of water and thoroughly mix
to reduce stiffness.
For hand mixing
Blend dry mix
with a shovel or hoe from the outer edges
working the material towards the center.
Continue mixing until all free water
is used and all the aggregate is uniformly
coated with cement.
For mechanical mixing
Mix the material for three minutes.
PLACEMENT
Place material until it slightly overfills
the forms. Consolidate to remove any voids
by using manual or mechanical vibration. Strikeoff with a screed or straight
edge board.
FINISHING
Allow bleedwater to evaporate before finishing. Use a float to achieve a smooth finish or a broom for a rougher surface. Caution - Overworking could weaken the surface and result in cracking, dusting or scaling.
CURING
Dampen with a fine mist of water
for 24 hours or moist cure with wet
burlap and polyethylene.
Alternatively, apply ProMasonry Cure & Seal.Protect from direct sunlight, wind, rain
and frost during the curing period.
CLEAN UP
Clean tools and equipment with water immediately after use. Cured material will need to be mechanically removed.
ProMasonry High Strength Concrete meets or exceeds
ASTM C387 specification for compressive strengths when used as directed.
