- Easy to Use - Fast Setting - Expanding
WARNING: Due to the expansion properties of Rockite do not
use Rockite for anchoring in cement that is narrow on top such
ramps, concrete construction barriers or concrete walls. When using
Rockite always leave at least 4 inches from the edge of the concrete
to the hole.
Material Safety Data sheet (MSDS
Use Rockite, for Anchoring:
Bolts - Rods -Post - Machines - Motors - Partitions - Appliances
- Railings - Conveyers - Racks - Seats - Deformed Bar - Tilt Up
Directions: How to mix the cement
Always use a clean container. Never add sand, gravel or other
foreign substances to Rockite. They weaken the cement and affect
Yield – Volume Calculation
1 lb Rockite Cement yields 18.75 cubic inches
92 lb Rockite Cement yields one cubic foot
QUANTITIES: imperial and metric
Fluid (pouring) Consistency:
Mix Rockite with water to a thick paste. Let the mixture stand for
about one minute. Then stir thoroughly. At this point, the mixture
will become more fluid. The proper consistency is more like a thick
batter, just fluid enough to pour BUT not WATERY. Keep the mix thick.
This makes stronger cement. Add water very sparingly. If the mix
is thin, add more Rockite promptly to thicken it. You wish to measure,
the correct water addition is 4 ½ oz. per lb. or 1 ½
pints per 5lb box. When using this method, MEASURE ACCURATELY
How to Anchor; Bolts, Post, Starter Rods etc in concrete, brick
- Drill the hole never less than 2 inches (50mm)
- Blow out all the dust and loose particles.
- Flush out hole with water. Be sure to remove excess water leaving
the hole clean and uniformly damp. (the substrate can be damp
when Rockite is poured into the hole)
- For anchoring machinery in concrete, use the fluid consistency
as above. Insure that anchor rods have nut head and washer on
before placing them in the opening. Pour the Rockite into the
space around the rod/bolt. Tamp bolt to settle Rockite completely
around the rod/bolt.
- For exterior anchoring of ornamental iron, pour the fluid consistency
(as above) around the rod, tapping the rod to settle the Rockite.
- For anchoring in vertical walls, use the plastic consistency
(see below) Fill the holes with the plastic cement first. Then
tamp the bolt or rod into place. If the cement becomes to fluid
because of the tamping process and sags out of place, let it stand
for a few moments and it will stiffen. Carry on with procedure.
- Let the cement harden for at least 30 minutes. (Initial set
is 15 minutes). For heavy equipment, allow one hour.
Note : DO NOT USE ROCKITE
IN SWIMMING POOLS
When used outdoors, ROCKITE should be allowed to dry out thoroughly
for seven days and then protected with a coat of good grade
exterior paint. ROCKITE should not be used underwater or as
a primary structural member. ROCKITE should not be used outdoors
for anchoring in porous materials, such as brick, limestone
and granite, when they are exposed to wet conditions.
For these types of applications use KWIXSET
Add only enough water to make the cement form dry lumps. Keep mixing
for 60 to 90 seconds. As the powder absorbs the moisture, the cement
will begin to look like ordinary putty. This is the proper consistency.
If you wish to measure, the correct water addition for the plastic
consistency is 3 ½ oz. per lb. When using this method, MEASURE
How to Mount Glass Balustrades Using Rockite and Kwikset
How to Patch holes and cracks in concrete floors:
- Cracks should be raked out t remove any loose debris or loose
particles. If a hole is to be repaired, chisel down the edges
to provide a 'form' for the cement when it is poured.
- If the hole is clean, simply remove lose chips and dirt.
- Sprinkle the whole/crack with water. Leave the surface damp
and not wet
- Mix Rockite to fluid consistency for patching floors and plastic
mix for walls.
- Pour a little cement into the hole and scrub it into the surface
with a stiff brush or broom to drive the cement into the pores.
This helps the patch t o adhere. Then add enough cement to match
the level of the surrounding surface. The cement will self-level.
- When the cement begins to thicken (about 10 minutes), smooth
out any imperfections in the surface with a cement trowel.
- After 30 minutes, sprinkle the patch with water. Foot traffic
and light trucking may be resumed immediately. For heavy trucking,
allow one hour.
Freezing Temperature Application
The procedure described in the foregoing may be used safely at temperatures
down to 25 degrees Fahrenheit. If the temperature is below 25 F,
keep the Rockite in a warm place before using. When ready to apply,
mix the Rockite with warm water and keep the mixture in a warm area.
As soon as the mixture begins to stiffen slightly, (approximately
10 minutes after the water is added) pour the mixture quickly into
place. The hardening process then creates heat and protects the
Rockite from freezing. Do not add anti-freeze compounds to the Rockite
(also available as a .pdf Rockite Specification Sheet 28k)
||The compound shall be a hydraulic type cement which, when mixed with water, will harden rapidly to produce a permanent bolt-setting anchor. The compound shall conform to the following specifications, all of which are based on the performance of the test specimens at room temperature and in laboratory air.
|| It shall be applied by pouring into place in a semi-fluid state, and shall be ready to use subject only to the addition of clear water.
|| It shall require no more than 3 pints of water to ten(10) pounds of compound to achieve a pourable consistency that will flow freely form an inverted container.
||It shall have an initial set of no more than thirty(30)minutes at 70O F and shall have a final set of no more than sixty (60) minutes as determined by Gilmore Setting Needles.
|| It shall not shrink on setting, but shall exhibit a slight
expansion of not more than 0.002 inches per lineal inch.
|Wight Per Cubic Foot:
|| It shall require no more than 92 lbs of dry compound missed with 3-1/2 gallons of water to fill one cubic foot of volume. Weight after setting up shall not exceed 120 pounds per cubic foot.
||Two-inch cubes made in accordance with ASTM standards tested on a Baldwin-Southwark Machine of 60,000 pounds capacity shall have the following average compression strengths:
||1 Hour - 4,500 psi
24 Hours - 5,000 psi
7 Days - 8,000 psi
|| The compound shall contain neither Portland cement, ferrous metals, nor rust-promoting agents.
|| the compound shall produce a setting with an average strain-bearing ability for each respective bolt and opening size, as shown in the following chart:
Bolt to be fastened *
Bearing Ablitiy (lbs.)***
* All bolts shall be equipped with a washer large enough to fit the diameter of the opening with only enough tolerance so that the washer will be free to reach and rest snugly against the head of the bolt at the bottom of the opening.
** Depths shown are based on opening drilled in sound concrete having compression strength of 3,600 lbs. per square inch. In the case of weaker concrete, the depth shall be increased to provide a greater purchase to the concrete, the depth shall be increased to provide a greater purchase to the concrete slab, This minimizes the danger of failure due to fracture of the concrete when subjected to extreme strains,
*** Data determined by test in which the strains recorded were limited to stresses sufficient to rupture mild steel bolts of each respective diameter, In no case was the setting injured.
