Proper Application of Precast Concrete Form Release Agents

Posted by Chuck Lohre on Mar 23, 2017 9:31:59 AM

(This week's Concrete Casting News post is a review of a National Precast Concrete Association Tech Note publication. You can read the entire document here, "Proper Application of Precast Concrete Form Release Agents." )

Proper Application of Precast Concrete Form Release Agents.jpgRelease agents, when properly used, aid in the stripping process, assist in producing sound defect-free concrete surfaces, simplify form cleaning and increase the working life of quality form surfaces. There are two main categories of form release agents:

  • Barrier – those that provide a physical barrier between the form and the concrete (such as petroleum-based products, soaps, synthetic resins, waxes)

  • Reactive – those containing fatty acids or other ingredients that react with the free lime in fresh concrete to produce a metallic soap interface between the form and the concrete (such as proprietary products and vegetable oils that are typically found in petroleum-based carrying agent products).

Concrete Form Release Application photo.jpgRelease agents should be applied to a clean form before the reinforcement has been placed to reduce the likelihood of inadvertently applying it to the reinforcement. If the release agent does come in contact with reinforcement it should be wiped clean before placing the concrete. When applying a release agent it is best to follow the manufacturer’s instructions. When too much form release is used, it is not only wasteful and inefficient, but it leads to a number of other associated problems with the finished product.

He who holds the wand determines the amount of material being applied, so proper training is crucial. As a rule of thumb, remember: Less is better. The amount needed to affectively coat a form is only about 0.005 inches thick. The actual cover thickness will depend on the application method and viscosity of the product, which is related to the ambient temperature. Typically, the colder it is in the plant, the thicker, or more viscous, the release agent will be. The warmer it is the plant, the thinner, or less viscous, it will be. Different measures can be taken during the application process to account for changes in material temperature (viscosity) throughout the year.

SPRAYING

Spraying is probably the most efficient and common method for applying release agents. Keep the wand moving when applying form release. Broad nozzle/flat spray tips have been found to give the thinnest and most uniform cover. It should be noted that as the temperature drops and viscosity increases, the spraying pressure should be increased and the nozzle orifice size reduced. As temperatures rise, reduce pressure and increase nozzle size. It is a good practice to soak or mop up any puddles that may have formed at the bottom of the form Remember: Less is better. Only through experience and training will you learn what works best for your plant’s production line.

CAUTION: Fatty acids will react with brass, bronze, aluminum, grey ductile and malleable iron and mild steel, as well as some petroleum-based products used for making blockouts and other embedded items. It is best to use stainless steel, nickel or plastic for your spraying systems and to test for possible reaction of embedded materials prior to full implementation.

SWABBING AND PAINTING

Swabbing and painting by hand is an acceptable application method, with the benefit of eliminating the majority of airborne particulate. On the negative side, applications tend to be thicker than necessary, leading to wasted material and the potential for additional problems. WIPING Wiping is often the method of choice for architectural precasters concerned with a blemish-free surface. Wiping on release agents with a sponge or rag will normally result in the thinnest coating, but it is very labor intensive.

DIPPING

Automated dipping systems are fast, labor efficient and ensure complete coverage. Excess material will usually drip back into a holding tank, reducing material waste. The application coat is often thicker than necessary, however, again creating the potential for future problems.

Choosing wrong release agent creates concrete bug holes

Posted by Chuck Lohre on Mar 17, 2017 4:45:39 PM

(This week's Concrete Casting News post comes from a YouTube video that illustrates how the selection of concrete form release affects the production of concrete bug holes. Many questions in the comment section ask what the two release agents were. We can guarantee that all Hill and Griffith products are engineered to reduce the formation of bug holes by using reactive fatty acid/methyl esters that react with free lime on the surface of the casting.)

From Paolo Redaelli, "Effects of two releasing agents of the surface of a properly vibrated concrete. Please note the one on the left having a perfect surface after very few seconds while the one on the right keeps forming bubbles of air."

Concrete Form Release for Wood

Posted by Chuck Lohre on Feb 23, 2017 2:50:22 PM

(This week's post comes from a HOMEGUIDES' article, "How to Keep Concrete From Sticking to Wood." It has a unique perspective from the homebuilder's point of view. You can read the full article here.)

How to Keep Concrete From Sticking to Wood

Concrete-Form-Release-For-Wood.jpgConstruction professionals routinely use plywood panels as shaping forms when pouring concrete for new home foundations. If the wood forms were treated properly with a form release agent, you can easily pull them away after the concrete dries. A do-it-yourselfer can pour concrete between 2-by-4 forms when installing a new sidewalk or patio, but for best results, pretreat the wood in the same way the pros do.

(Caption: Hill and Griffith recommends Grifcote Bio Gold concrete form release for wood. A non-petroleum, non-staining concrete form release that is both VOC compliant and biodegradable.)

Oil-Based Release Agents

At one time, construction professionals would create their own oil-based form release agents using materials such as diesel fuel, home heating oil and mineral oil to keep poured concrete from sticking to wood. Today's homebuilders often select stick-resistant plywood or OSB panels pretreated at the lumber mill with proprietary chemical blends that may include parafin, mineral oil and linseed oil. Some concrete contractors extend the stick-resistant life of the plywood by using a refresher coating of a commercial release agent or a solvent-thinned linseed oil.

Water-Based Barrier Agents

Water-based release agents can also keep concrete from sticking to wood forms, and unlike oil-based formulas, they do so without releasing high levels of volatile organic compounds into the air. VOC-releasing chemicals are highly regulated in some regions because they contribute to atmospheric smog. Commercial water-based release agents are produced from plant-based materials and are less likely to discolor the concrete's surface. Ordinary vegetable oils can serve the same purpose if applied in two or three successive coats.

Reactive Release Agents

Chemically active release agents react with the alkalinity of the concrete to prevent the concrete from sticking to wood molds and forms. Commercial products of this type are formulated with a fatty acid and a soapy surfactant that react chemically with the concrete to help create a clean, unstained concrete surface with a smooth edge. At the same time, they create their own thin chemical membrane that blocks the concrete from infiltrating the wood's pores.

NSF Potable Water Concrete Form Release

Posted by Chuck Lohre on Feb 16, 2017 2:22:35 PM

(This week's post comes from the National Sanitation Foundation. It's a review of what is on their web site about potable water concrete form release. You can read more by going to their web site.)

NSF/ANSI 61: Drinking Water System Components – Health Effects

Potable-Water-Concrete-Form-Release.jpg

If you manufacture, sell or distribute water treatment or distribution products in North America, your products are required to comply with NSF/ANSI 61: Drinking Water System Components – Health Effects by most governmental agencies that regulate drinking water supplies. Developed by a team of scientists, industry experts and key industry stakeholders, NSF/ANSI 61 sets health effects criteria for many water system components including:

  • Protective barrier materials (cements, paints, coatings)
  • Joining and sealing materials (gaskets, adhesives, lubricants)
  • Mechanical devices (water meters, valves, filters)
  • Pipes and related products (pipe, hose, fittings)
  • Plumbing devices (faucets, drinking fountains)
  • Process media (filter media, ion exchange resins)
  • Non-metallic potable water materials

Cleveland Rocks with Grifcote FR 50 Concrete Form Release

Posted by Chuck Lohre on Feb 2, 2017 3:49:18 PM

(This week's post comes from CONCRETE PRODUCER and their article titled "Cleveland Rocks, Allega Cos. answers Corps contract commanding nearly 120,000 tons of wave-worthy precast." Here's a link to the article. They included this statement about Hill and Griffith in a caption to one of the photos, "Lindsay Precast Concrete demonstrated handling and stripping features of a prototype prior to a nod from Anthony Allega for 49 additional dolos forms. After testing a handful of form oils, the producer opted for Hill & Griffith’s Grifcote FR 50 Concrete Form Release.")

Cleveland Rocks 

Hill & Griffith’s Grifcote FR-50.

 

A weather front emanating from Superstorm Sandy in October 2012 tested infrastructure well inland of metro New York and New Jersey, the area hardest hit by precipitation, wind and storm surge. Among federal and state agencies contending with long-term responses to Sandy-level exposure is the U.S. Army Corps of Engineers Buffalo District. It capped the 2015 and 2016 construction seasons closing repair and upgrade contracts—Oswego Harbor Detached Breakwater, New York; Cleveland Harbor East Breakwater, Ohio—using non-proprietary precast concrete structures known as dolosse, in tandem with limestone or granite armor block.

District engineers outlined finished structure air content, flexural and compressive strength, plus surface quality specifications for respective Oswego and Cleveland project precasters, Lakelands Concrete Products of Lima, N.Y., and Allega Cos. of Valley View, Ohio. Both determined that highly fluid, self-consolidating mixes are the best solution for accelerated production of structures that will be submerged or subject to frequent Great Lakes wave exposure through a service life plausibly extending into the next century. Early indicators suggest the dolosse installations contribute to a Corps roster proving the efficacy of SCC for structures prone to extreme weather or temperature events, sharp freeze-thaw cycles, and rare, but catastrophic loads.

Hill & Griffith’s Grifcote FR-50.

Dolosse resist breakwater or shoreline erosion from waves and undercurrent through their mass and energy-dissipating geometry. Known as dolos individually, the monolithically cast structures comprise three members of octagonal cross section: Uniformly sized shanks connect fluke ends. The latter are flared, tapered members running in opposite directions, along X and Y axes. Dolosse are fabricated in four- to 16-ton sizes, sans lifting hardware, and placed by sling so each structure interlocks such that even the most forceful waves or undercurrents meet long plain or reinforced precast concrete chains of inordinate tonnage.

The Corps Buffalo District used a formula factoring statistical 20-year wave height and 10-year water level to determine 16-ton and 6.5-ton dolos sizes for the New York and Ohio installations. Located near the southeastern corner of Lake Ontario and serving the first U.S. port from the St. Lawrence Seaway, the upgraded Oswego Harbor structure marks the District’s first use of 16-ton dolosse. Lakelands Concrete fabricated 997 of the 11-ft. long structures with conventional reinforcement (Concrete Products, July 2015). The dolosse represented the bulk of a $19 million contract Michigan’s Durocher Marine completed in November 2015.

Slightly trailing the New York engineering and casting schedule were preliminaries for the much more ambitious Cleveland Harbor work, centered in Lake Erie about two miles east and one-half mile north of downtown Cleveland. Buffalo District engineers specified the 6.5-ton dolosse, plain and 8.3-ft. long, for 4,400 feet of breakwater structure, which sustained more than $31 million in damage attributable to the Superstorm Sandy-spurred weather system. The Corps found that the intensity of the winds over Lake Erie created extraordinarily rare waves, measured at nearly 18 feet offshore of Cleveland.

IMAGE

Great Lakes Dock & Materials customized a precast handling device in house, and turned to a GPS-guided, crane cable-mounted topographical 3D system, Posibloc, for precise dolos placement. Companion Visibloc technology recorded each unit’s location, so the crane operator could target subsequent placements for optimal density and interlocking. Although not Posibloc-prescriptive, the Cleveland Harbor contract required a system a) with positioning technologies and sensors to produce a 3D image of dolos being placed; b) capable of guiding the crane operator to place units in designated positions with interlocking control; and, c) equally accurate above and under water.

The contractor deployed two 100-dolosse barges for June 2015–November 2016 breakwater repairs and upgrades. Anthony Allega Inc. began fabrication in April 2015, whereby Great Lakes Dock & Materials approached peak season with a two- to three-month dolosse inventory. SITE PHOTOS: Andrew Kornacki, Corps Buffalo District

CONTRACT ESCALATION

MasterGlenium HRWR assured self-consolidating properties in the mixes for the dolosse, each requiring 3.25 yd. Between its rapid placing rate and zero vibration requirements, the self-consolidating concrete proved critical to a 300- to 350-dolosse weekly production schedule. Allega Cos. mobilized fabrication at its headquarters property, running on both sides of the Interstate 480 crossing at Valley View, Ohio. PLANT PHOTOS: Concrete Products

After securing the precast contract, Allega Cos. mapped a dolosse production and storage plan at its headquarters, south of Cleveland and about 15 miles from a precast off-loading point. The site is the base of fleet and plant equipment supporting Anthony Allega Inc., a building and heavy/civil contractor operating mainly in Ohio; and Allega Concrete Corp., a four-plant, northeastern Ohio ready mixed producer.

Seasoned in precast barrier and sound wall fabrication, Anthony Allega enlisted Canal Fulton, Ohio-based Lindsay Concrete Products to fabricate 50 forms, enabling 300 dolosse output on a six-day schedule. Through lead Cleveland Harbor contractor Great Lakes Dock & Materials LLC, Muskegon, Mich., the Corps initially called for 12,577 dolosse. Anthony Allega was set to cover that quantity over an April 2015–October 2016 production window. Site assessments, coupled with the availability of additional funding, compelled Buffalo District engineers to increase the precast order to 18,257 dolosse. The schedule for two shifts of casting plus form stripping and maintenance crews went from six to seven days a week in 2016.

The option of self-consolidating mix specifications allowed Anthony Allega and Lindsay Precast to design freestanding dolos forms, with the 1.67-ft. octagonal end of a fluke serving as the lone charging port. Individual stands bear two hinged form sections: one main, with full 8.3-ft. fluke and shank tapering from 2.67 to 1.67 ft.; the other with remaining fluke and clamped end. Anthony Allega staged production between a 200-yd./hour batch plant and storage area equal to 2,000 dolosse.
