Application of Fire Barrier Mortar

What's special about this fire protection mortar?

Variable Mix Ratio: permits self-leveling as well as no sag (no forming) application consistencies, resulting in labor savings
Excellent Adhesion: will bond to concrete, metals, wood, plastic and cable jacketing
Re-enterable without use of power tools: results in lower maintenance costs due to ease of making cable changes

3M™ Fire Barrier Mortar is a lightweight cementitious firestop product. It is available in poly/paper bags and ready for mixing with potable water. 3M™ Fire Barrier Mortar does not contain MMMF (man-made-mineral-fibers) or asbestos and does not require fibrous damming materials. 3M™ Fire Barrier Mortar contains binders free of portland cement and therefore has greater resistance to common concrete poisons than PC bound products.

For use in mechanical and electrical penetration firestopping.

Bonds to Itself: proven prior and during fire testing, resulting in proven and tested repair procedures
MMMF and Asbestos Free
Polypropylene-Fiber Reinforced: reduces cracking during cure and firing
Pumpability: allows faster installations, resulting in labor savings on larger projects and reduced installation time
Tested with a large variety and thickness range (up to 6”/15 cm) of pipe coverings and jackets
Excellent Heatsink: resulting in absorption of heat from penetrants, reducing the likelihood of ignition of combustible matter on the unexposed side of the assembly
Compression Strengths: are between 186 and 790 PSI (1.3 to 5.45 N/mm2), depending on the water/cement ratio (1 part water to 2.5 parts powder to 1:4)
Tested with 3’ x 6” (91 cm x 15 cm) Cable Trays, with 1C1000MCM Power Cables and Other Cables up to 45% Actual (100% Visual) Tray Fill
Tested with 3’ x 6” (91 cm x 15 cm) Aluminum and Galvanized Steel Ladder Trays
Tested with a 4500A bus duct with Copper or Aluminum Bars
Tested and Certified for Use with “Slip-Covers”: resulting in the ability to isolate and permit movement of penetrates without rupture of the seal

Sample specifications are provided under separate cover. CAUTION: firestopping is ideally specified under Section 07270, as a separate work scope tendered by specialty, 3M trained, applicators to the general contractors. Specifiers are advised to instruct the chief designer to provide clear identification of wall ratings in the form of overlays on separate drawings.
