Bolt Anchor Sulfaset
I. PURPOSE:
To inform maintenance personnel on the
procedure for using Bolt Anchor Sulfaset for
potential application during powerplant or
pumping plant modifications.

II. GENERAL:
F-181 W Bolt Anchor Suifaset is an anchoring
cement used for setting anchor bolts in concrete.
Suifaset is a dry powder; when mixed with water,
it forms a fast setting anchoring cement. Sulfaset
expands as it sets to lock the bolt to the concrete.
The manufacturer states that 100 pounds of
sulfaset is required to fill a 1-cubic-foot volume.

Use F-181 W sulfaset instead of F-181. The W
sulfaset is made for wet climates; and in
Bonneville Power Administration Laboratory
tests, it weathered better than the F-181.

An advantage of suifaset is it can be used in
inclement weather. With epoxy anchoring
cement, the concrete hole had to be dried by
burning alcohol in it, and the temperature was
kept above 55

a good set.
III. PROCEDURE:
A. Drill Hole
Drill a hole in the concrete large enough to
accommodate the bolt head. Hole depth
should be a minimum of 4 inches deep.
Laboratory tests showed bolt pullout strength
increases with hole depth.

1. Star drill. - An air hammer with a star
drill can be used. Problems occur with
large bolts since star drills are not large
enough to drill holes to accommodate
them. Bolt head can be cut off, but the
pullout strength is reduced by roughly 4/5.
If possible, grind off the bolt head, leaving
enough head into which the sulfaset can
bite.

2. Core drill. - Use the small core drill
which drills up to 2-inch-diameter holes. A
2-inch hole should accommodate most
anchor bolts.

B. Clean Hole and Place Bolt
Clean ail loose material from the hole and
place the bolt in it. The addition of a washer
on the bolt made little difference pullout
strength tests conducted by the Bonneville
Power Administration Laboratory.

C. Mix the Sulfaset
Mix a small amount of suifaset with water.
Stir until the mixture is smooth and creamy,
about the consistency of pancake batter.

D. Fill Hole
Pour the mixture into the hole while jogging
the bolt up and down to prevent air pockets.

Sulfaset comes in 1- and 5-gallon cans. A 1-
gallon can is most practical for maintenance
since that amount will normally do one job.

G. Storing
Store sulfaset in a dry place. It will set up
after the can is opened if it is stored for a
long period in a humid area.
