FIREROK is a high early strength, heat resistant, pozzolan cement, structural
repair, concrete mix. FIREROK’s™ unique chemistry withstands exposures
to intermittent high temperature environments. It is a single component
powder that is water activated. FIREROK packaged units have 30 to 45
minutes of working time and reach compressive strengths of >2,500 psi
(17.2 MPa) in 4 hours.
FIREROK has been designed for areas which are exposed to high
temperatures either from an intermittent or a continuous heat source. This
would include runway areas exposed to jet blast or APU exhaust, HPU’s,
and oven and metal casting areas.
• Substrates must be of load bearing capacity, and free from all potential
bond breakers such as dirt, dust, grease, oil, sealers, curing compounds,
laitance, loose or deteriorated concrete and any bond-inhibiting foreign
• Mechanically prepare surfaces to achieve a Concrete Surface Profile
(CSP) 5 - 7 per ICRI Guideline 310.2R-2013.
• All surfaces to be repaired should be saturated surface dry (SSD) but have
no standing water. Hot surfaces should be cooled and shaded while cold
surfaces should be heated and sheltered. Mechanically remove all loose
materials by suitable means such as chipping hammer, chisel, sandblast,
high pressure water blast (>5000 psi), or similar methods.
Standard Mixing Procedures (Rotating Drum Concrete Mixer).
Mix minimum 2 units at a time.
1. Pre-wet cement mixer with water then drain all water from mixer (away
from repair area).
2. Start mixer and add 50% of total required mix water to concrete mixer
(FIREROK requires 2 quarts (1.9 L) of water per 53.5 lb (24.3 kg) unit,
therefore 2 units require 4 quarts (3.8 L), etc.)
3. Add pre-determined units of FIREROK, mix for 1 minute.
4. Add in remaining 50% of mix water.
5. Mix for 6 additional minutes/ 7 minutes total.
6. Pour all contents into repair area.
7. Clean mixer or repeat process for next batch.

• In ambient temperatures, >40°F/4°C:
use warm water (70°F/22°C to 90°F/32°C).
• In ambient temperatures >85°F/29°C:
use cooler water (50°F/10°C to 60°F/16°C).
• Working times will vary when mix water temperature’s are outside of these
• Do not re-temper. The addition of excess water will negatively affect the
materials final properties.

Application & Finish:
• Do not place FIREROK in temps below 40°F/4°C and above
120°F/49°C. Working times are influenced by surface temperature.
In ambient temperatures above 85°F (29°C), utilize ACI hot weather
• Working time can be extended by adding Aquafin’s Set Retarder
Admixture to mix water. (See Set Retardant product data sheet for more
• Minimum product placement thickness is 1.25” (3.2 cm). There are no
restrictions to the depth of the product thickness.
• For best results, Aquafin recommends monolithic placement of repair
materials. Maintain a minimum thickness of 1.25” (3.2 cm) if repair
material must be layered. Material must also be layered before final set
has been reached.
• Upon initial set, a broom finish can be applied. Upon final set, the material
can be saw-cut, drilled, sanded and/or polished.
• All previously existing joints must be re-established within 2-3 hours of final
• General loading in 2 hours for wheeled traffic and 1 hour for foot traffic
after addition of water. Add 30 minutes for every 10°F (6°C) drop in
• Self-curing, do not water cure.
