Forment®

Forment® is an economical repair mortar for large repairs such as parking garage, balconies, and decks. Forment can be poured or pumped into place.

Where to use:

Formed structural and protective repairs to vertical, overhead, and horizontal concrete from 1 – 6 inches deep.

How to apply:

Pump/pour. Additional Information

Performance Characteristics

Shrinkage compensated
  • Maintains integrity of repair, resists cracking.
Thermal Compatibility
  • Prevents delamination due to temperature change.
Corrosion Protection
  • Protects reinforcing steel in repair zone and suppresses ring anode effect.
Durable
  • Resistant to weathering action, excellent freeze/thaw stability and abrasion resistance.
Very Low Permeability
  • Resistant to deicing salts, carbonation, chloride, and chemical attack.
Highly flowable
  • Excellent consolidation around reinforcing steel.
Economical
  • Fast placement of large repairs, improves productivity.
Two component
  • Consistent batching and flowability.

Surface Preparation

  • Remove loose and deteriorated material, laitance, dirt, dust, oil and any surface contaminants that will inhibit proper bond.
  • Saw cut edges with a diamond blade at a 90° angle to eliminate feather edging. Avoid polishing the edges as this will inhibit bond.
  • Avoid bruising or micro cracking during surface preparation. Refer to ICRI Surface Preparation Guide 03732.
  • Apply Conpro Start where a consolidant is of benefit.
  • Repair zone must be an average of 1 inch deep, square or rectangular shape.
  • Remove concrete from corroded steel and several inches beyond to expose non-corroded steel.
  • Provide a 3/4 inch clearance between the concrete and steel.
  • Damaged reinforcing steel should be inspected by a qualified engineer and appropriate action taken.

Priming

Concrete
  • Several hours prior to placing Forment, fill the formwork with clean water. Immediately prior to placement completely drain the water and seal the ports.
Reinforcing Steel
  • Remove all scaling rust from reinforcing steel.
  • Apply ECB anti-corrosion coating.

Mixing

  • Mechanically mix using a low speed drill (400-600 rpm) and mixing paddle or mortar mixer.
  • Pour Forment admix into a clean mixing vessel and slowly add all of the powder.
  • Mix continuously for 3 minutes to a uniform, lump-free consistency.
  • Do not overmix, as this will entrain excess air.

Application

  • Formwork must be tight at all joints to prevent leaks and loss of water and material.
  • Pre-treat forms with a release agent.
  • Locate vent holes at bottom of forms to allow pre-soaking water to drain and at top to allow air to escape during placement. Refer to ACI 347-01, Guide to Formwork for Concrete.
  • Fill forms with clean water several hours prior to placement.
  • Drain forms immediately prior to placement.
  • Fill forms with a continuous feed. Do not interrupt filling once started, as this will create voids. Refer to ACI 304.2R-96, Placing Concrete by Pumping Methods.
  • Consolidate material by tapping forms lightly with a 3 lb. hammer.
  • Forment will remain fluid for approximately 30 minutes at 70°F, 50% RH.
  • Strip forms after 48 hours.
  • Extend material to a maximum of 30 lbs. of 3/8 inch aggregate per 50 lbs. of Forment. Aggregate must be non-reactive, low absorption, graded and high density.

Curing

  • Dampen the repair with a fine mist of water for 24 hours or moist cure with wet burlap and polyethylene.
  • Protect repair from direct sunlight, wind, rain and frost during curing period.

Clean Up

  • Clean tools and equipment with water immediately after use. Cured material must be removed mechanically.

Coverage/Yield

  • 0.41 ft³/50 lbs.
  • 0.65 ft.³ when extended with 30 lbs. of 3/8 inch aggregate.

Product Handling

Packaging
  • 50 lbs. paper bags; and 1 gallon Forment admix.
Shelf Life
  • 12 months when properly stored.
Storage
  • Transport and store in cool, clean, dry conditions in unopened containers.
  • High temperature or high humidity will reduce shelf life.
  • Protect admix from freezing.

Limitations

  • Do not apply unless substrate and ambient temperature can be maintained at a minimum of 40°F for 24 hours. Refer to ACI Cold Weather Application Guidelines.
  • Do not add more liquid than specified.
  • Do not add water.
  • Begin curing procedures as soon as forms are stripped.
  • Material should not sit in mixer, pump or lines for more than 5 minutes without recycling.
  • Do not use Conpro Primer as a bonding primer with Forment.

Health and Safety

  • Product is alkaline.
  • Do not ingest.
  • Avoid breathing dust.
  • Avoid contact with skin and eyes.
  • Refer to Safety Data Sheet (SDS) for additional information.

First Aid

  • In case of skin contact, wash thoroughly with soap and water.
  • In case of eye contact, flush immediately with a high volume of water for at least 15 minutes and contact a medical professional.
  • For respiratory problems, remove person to fresh air.

Large repairs are particularly well suited for a repair mortar that is very fluid so that it can be poured or pumped into repair zone.  Forment is also well suited to repair zones that are congested with rebar.   

Under normal conditions the forms can be removed after curing for 24 hours.     

Form and pour applications have the additional advantage being self-consolidating and not requiring the same level of expertise as hand applied applications.  

Forment can be extended with up to 30 lbs of 3/8 inch aggregate to increase yield.

Projects Showcase

Wean Hall

Project History

Wean Hall houses part of Carnegie Mellon University’s School of Computer Science. It was designed in the Brutalist style popular in America during the 1950s and ‘60s and built in the early ‘70s following the fashion of the day and according to the drawings of Architect Dahlen Ritchey.
The building currently serves mainly as classroom space but features a prominent cube, positioned over the main entrance, containing a windowless lecture hall. It is setback from but situated amongst a quadrangle of Classical-style buildings and was showing signs of aging, common with concrete structures in colder climates. Corrosion of reinforcing steel was causing spalling and cracking in the building’s façade and was untreated until renovations began the summer of 2013.
Engineering plans called for exposing the rebar, proper preparation of the repair zones and encasing the voids in forms to be left in place up to a week to minimize future cracking. Conproco’s Forment®, which consistently produces high quality repairs, was poured into the forms ensuring that the rebar would be completely encapsulated. The contractor hand shaved the patches to insure a more uniform appearance. Conpro Lastic was hand rolled in two coats to insure a waterproof membrane and create a uniform and aesthetic appearance.
All repairs and improvements were completed by the fall of 2014 and in time for the Computer Science Department’s 50th anniversary celebration in 2015.

 

Campbell’s Building 70

Project History

The exterior wall panels of the Campbell’s Soup Company building were deteriorating. Reinforcing steel was too close to the surface, and the resulting corrosion was causing the precast panel fins to spall. Conproco offers a system that proves reliable in the field. Engineers from Keast & Hood were convinced after seeing a similar project completed over 10 years prior.
