- High initial and ultimate flexural and compressive strengths
- Non-porous, high density grout resistant to water and salt penetration and damage from freeze/thaw cycles
- Non-shrink, high fluidity and controlled expansion provide full load bearing coverage
- Non-metallic, non-staining and non-corrosive
- Contains no chlorides or other salts detrimental to reinforcing steel
- Can be extended with proper aggregate by up to 50%
- Conforms to CRD-C621 Corps of Engineers Specification for Non-Shrink Grout and ASTM C-1107
Applications & Uses
- Markets
- Applications
- Precision grouting of machinery bases sole plates, rolling mills, generators, anchor bolts, transfer lines, paper mills and structural grouting of precast columns, crane rails, bridge seats, dowels, etc.
- Grouting applications where shrinkage must be eliminated and corrosion and staining cannot be accepted.
- Processing
Preparation:
All materials should be stored at 4°C to 27°C 24 hours prior to installation.
- All grout surfaces must be solid, completely free of oil, wax, grease, sealers, paint and other contaminates that may act as a bond breaker.
- Unsound concrete must be chipped away, leaving a rough solid surface insuring bond.
- Prior to grouting, areas should be saturated with water for 12 - 24 hours after which all excess water is removed. This produces a saturated surface dry (SSD) grouting area.
- Forms must be sealed to prevent water or grout escaping and provide for rapid continuous grout placement. When placing provide an angle in the forms high enough to assist in grouting.
- For pouring minimum openings of 76 mm for entry and 152 mm for “head” are recommended. Venting must be provided to avoid entrapping air. Forms should be at least 25 mm higher than the bottom of the base plate.
- Maintain ambient and surface temperatures between 40ºF and 95ºF. Set times and strength developments are dependent on temperature. Hot temperatures will accelerate physical properties while cold will have a retarding effect.
Job Mockups:
The manufacturer requires that when its ProSpec® products are used in any application or as part of any system that includes other manufacturers’ products, the contractor and/or design professional shall test all the system components collectively for compatibility, performance and long-term intended use in accordance with pertinent and accepted industry standards prior to any construction.
Mixing:
Water Requirements
Desired grout consistency- Plastic (trowel consistency): 3.6 L of clean potable water per 22.7 kg
- Flowable (pumping consistency): 3.8 L of clean potable water per 22.7 kg bag
- Fluid (pumping consistency): 4.3 L of clean potable water per 22.7 kg bag
Note: The water quantities shown are approximate and may vary slightly with type of equipment and application conditions. Do not overwater.
- Only mix with clean potable water and/or for thicker applications extend with clean SSD 9 mm pea gravel. Addition of cold water at high temperatures or warm water at low temperatures will aid in adjusting the mix temperature.
- Place 3/4 of desired mixing water, start mixer, then slowly add the dry material. After all of the powder has been added, slowly add the remaining 1/4 water until the desired consistency is achieved.
- Avoid adding excessive amounts of water that promotes segregation or bleeding of the grout.
- Mix mechanically with a high torque electric drill, do not exceed 600 rpm using a paddle type mixing blade or an appropriately sized mortar mixer.
- Mix for 3 - 5 minutes to ensure a uniform lump free consistency and place immediately
Note: More or less water may be required to achieve a 25 - 30 second flow or the desired mixing consistency depending on the temperature and other variables.
Application:
Apply when air and substrate temperature are between 4ºC and 32ºC.
- Fluid working time 30 minutes at 21ºC.
- Agitate material as necessary within its working time to maintain workability.
- Shut down nearby machinery prior to and during placement.
- Provide vent holes where necessary.
- Pour and place grout from one side of form to eliminate air voids.
- A vibrator, rod, chain or trowel may be used to assist in consolidating the grout and eliminating air voids. Use a mixer large enough to permit continuous placement before any part of the grout has set.
- Confine grout to ensure minimum surface exposure. Avoid vibration for 24 hours after placement.
- For placements greater than 76 mm, extend the grout with 11.3 kg of washed clean SSD (saturated surface dry) 9 mm graded aggregate per 22.7 kg bag.
- After placement, immediately trim the surfaces and edges with a trowel.
- Minimum application thickness is 25 mm.
- Forms may be removed after grout has hardened to an initial set.
Jobsite Testing:
Jobsite strength tests must use ASTM C 1107 specifications 51 mm metal cube molds. DO NOT use cylinder molds or plastic cube molds. Control testing based on achieving the desired flow rather than water content.
- Forms may be removed after the grout has hardened to an initial set and retains its shape. This time period will vary according to temperature. At this point final finishing and curing can start.
- The grout should slope downward from baseplates or similar structures at a 45º angle from the lower edge.
- Prevent rapid water loss by covering the exposed grout surfaces with wet burlap during the first 48 hours or apply an acceptable water based cure and seal agent.
Cleaning:
Use water to clean all tools immediately after use. Dried material must be mechanically removed.
Limitations:
- Do not overwater.
- Do not use in applications of high dynamic loading.
- Do not allow portland cement-based materials to come in direct
- contact with uncoated aluminum.
- Do not retemper grout by adding water.
- Do not use as a floor topping or in large areas with an exposed
- shoulder around base plates.
- Do not add accelerators, retarders, plasticizer or other additives.
- Do not apply in applications thicknesses 25 mm.
- Do not mix more grout than can be placed in 20 minutes.
Coverage:
- One 22.7 kg bag yields approximately 0.01 m³ at 4.3 L of water.
- One 22.7 kg bag extended with 11.3 kg of washed pea gravel 10 mm yields approximately 0.02 m³ at 4.3 L of water.
