Review: "Guide for Surface Finish of Formed Concrete"

Posted by Hill and Griffith Company on Dec 6, 2018 1:05:46 PM

(This week's post is a review of the American Society of Concrete Construction's "Guide for Surface Finish of Formed Concrete." You can read it at Google Books here.)

Amazon Book's summary (April 1, 1999), "Exactly what is a smooth-form finish? What is a rough-form finish? To what extent are bugholes, voids and fins acceptable in each type? This easy-to-use guide explains and illustrates the answers to these questions and, even more importantly, serves as the standard for the differences between as-cast structural concrete finishes. The succinct, yet thorough, text includes a glossary and a handy table on as-cast finishes. But the guide's Presentation Photos are what make it truly unique. Three sets of 6 different, full-scale photographs depict various as-cast finishes, with bugholes and voids ranging from 1/16" or less to 2" across. Attach a Presentation Photo to a bid or specification to show what surface finish is to be expected."

Form Release Agents

Release agents are differentiated from form coatings or sealers that are usually applied in liquid form to contact surfaces either during manufacture or in the field. Coatings and sealers serve one or more of the following purposes:

  • Alter the texture of the contact surface 
  • Improve the durability of the contact surface
  • protect the contact surface from moisture

Release agents, on the other hand, are applied to the contact surface of the forms to prevent bond to the concrete and thus facilitate stripping. They can be applied to form materials during manufacture or applied to the form before each use. Manufacturers' recommendations should be followed in the use of coatings, sealers, and release agents (Reference 10-11), but ACI 347 recommends independent investigation of performance before using a new product.

There is no ACI standard to define these products, but the term form oil is frequently applied to petroleum compounds originally intended for other applications such as diesel fuel or heating oil, while release agent more often refers to products containing proprietary reactive ingredients specifically formulated for use on concrete forms. Release agents are commonly classified on the basis of how they act instead of what is in them. The two basic categories are barrier agents and chemically active agents, sometimes called reactive agents. Some release agents are a combination of the two types.

Barrier type releases agents create a physical barrier between the form surface and the fresh concrete, preventing the concrete from sticking to the form. Familiar examples are home heating oil, diesel oil, and used motor oil. U.S. environmental regulations prohibit the sale of these commodities as release agents, but they have been widely used because they are inexpensive and readily available. They are applied in relatively thick films, covering 200 to 600 sq ft per gallon, and such heavy applications can increase surface staining and bugholes on the concrete surface. If coated forms are left for several days before concrete is placed, barrier oils may evaporate, possibly leading to some sticking of the concrete to the form.

Chemically active or reactive agents contain an active ingredient that may be dissolver in an oil-based carrier or emulsified in a water-based carrier. The active ingredient is typically some type of fatty acid derived from plant or animal sources, and it combines chemically with calcium ions in the fresh concrete. The reaction product is a thin layer of what chemists refer to as a grease or metallic soap or salt; non-water-soluble, it permits the form to release readily from the hardened concrete.

The reactive fatty acid components are generally considered biodegradable and have found favor in the past decade because of increasingly stringent environmental regulations. For similar reasons, manufacturers have also been turning to water-based carriers, which will probably be subject to freezing.

American Concrete Institute's Frequently Asked Questions - "Form Release Agents"

Posted by Hill and Griffith Company on Jun 7, 2018 3:46:19 PM

Form release agents

Review of an article published by the American Concrete Institute's "Frequently Asked Questions" section of their website.

Form Release Agent

Q. I need to select a form release agent for a new project requiring an architectural finish. Can you provide information on different types of form release agents and recommendations for using them? Does ACI have a publication on form release agents I could use as a reference?

A. Form release agents ease formwork removal, extending the useful life of a form and improving the smoothness and texture of concrete surfaces. Two main types are available: barrier and chemically active.

Barrier-type agents (examples include diesel oil, wax, and silicone) create a barrier between the form and the concrete. These are not recommended for architectural concrete, because they can cause stains, surface air voids, and problems with form removal in very cold or very hot weather; they also may prevent subsequent adhesion of coatings to the hardened concrete. While diesel oil was once commonly used, it’s now prohibited because the associated volatile organic content (VOC) emissions contribute to smog. (Note: In the United States, form release agents have to meet federal VOC limits of 450 g/L [3.8 lb/gal.] and may have to meet more restrictive limits of 250 g/L [2.2 lb/gal.] in some states.)

Chemically active form release agents (certain types of fatty acids) react with calcium ions in the cement paste to produce a soap that prevents concrete from bonding to the formwork. Based on the reactivity, they are divided into buffered (partially) reactive and fully reactive. Buffered agents produce an improved soap film that helps remove entrapped air and may promote better flow of a thin skin of cement paste at the surface of the form. Fully reactive agents can provide a good basic soap film that, depending on the brand, works well in most cases. Because chemically active form release agents produce fewer bugholes, stains, and surface irregularities than barrier type of form release agents, they are commonly used for architectural concrete.

For more information on this topic refer to ACI 347R “Guide to Formwork for Concrete”, ACI 303R “303R-12 Guide to Cast-in-Place Architectural Concrete Practice”, and ACI 533R “Guide for Precast Concrete Wall Panels”.

Review of Precast Concrete Form Maintenance Article in PRECAST INC Magazine

Posted by Hill and Griffith Company on Jun 1, 2018 12:57:27 PM

Besides Bob Waterloo's Featured article, "How To Lose a Customer in 10+ Easy Ways," the recent issue of PRECAST INC has some great tips from industry professionals about precast concrete form maintenance. Here are some highlights from the artcle.

Form manufacturers and precasters were asked several questions related to form maintenance and form safety. Below are the questions and answers from the responders. 

precast-concrete-form-maintenance-1

What steps should precasters be taking to keep their formwork in good working condition? 

"Using a quality form release and cleaning forms with every use will keep the
face of the forms clean for many years. The other best practice to increase the life of your equipment is to avoid hammering on them as much as possible - abstinence is the best policy here!" - Jim Aylward, Western Forms

"Keep forms clean, since build up can change the center of gravity on pieces and parts. Keep forms oiled for easier stripping." - Blythe Coons, Spillman Company

precast-concrete-form-maintenance-2

Any tips or best practices you would like to share with precasters to help increase the lifespan of their formwork and to ensure safety? 

"Biggest tips on increasing the life of aluminum formwork: 
1. Invest in quality.
2. Use quality form release
(reactive release designed for aluminum forms) to keep the forms clean.
3. Train employees to treat the equipment with care.
4. Use proper tools associated with the formwork.
5. Reach out to manufacturers for questions and concerns."
- Jim Aylward, Western Forms

"Don't try to save money on form oil. Figure out what works best for you and keep it. Don't allow employees to use hammers to clean forms. Grease all grease fittings regularly. Take time to clean the inside of the forms." - Mike Vergona, Garden State Precast

Concrete Form Release for Wood

Posted by Hill and Griffith Company 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 Hill and Griffith Company 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

 

Why Work With NSF?

NSF Potable Water Concrete Form Release 2

The NSF mark, well respected by public health officials and drinking water utilities, is recognized as a symbol of product quality and integrity. Our responsive, personalized service quickly guides your products through the certification process, ensuring that they get to market on time and on budget. We offer product bracketing services wherever possible to help keep costs down, and we provide pricing up front so there are no hidden surprises down the road.

NSF is accredited by the Standards Council of Canada (SCC) and NSF listings satisfy the requirements of the Canadian National Plumbing Code, U.S. Model Codes and the Uniform Plumbing Code (UPC).

Certification Process

NSF Potable Water Concrete Form Release 3

We distinguish ourselves due to our thorough product evaluation, but our certification process is simple and efficient. We assign you a dedicated NSF project manager as a single point of contact to guide you through the certification process and oversee your certification project every step of the way.

Seven Simple Steps to Certification:

  1. Your company submits an application.
  2. You provide product formulation, toxicology and product use information.
  3. Our toxicology department reviews formulations.
  4. We perform a plant audit and sample collection.
  5. Our laboratory conducts testing.
  6. We complete a final toxicology evaluation.
  7. We grant NSF certification for compliant products and you can use the NSF mark on products, packaging and marketing materials.

Our experts can help you reduce overall costs and expedite your time to market by bundling services and reducing the number of contracted service providers and facility audits.

U.S. and Canadian Approvals

Drinking water system components that are used in centralized water treatment plants and water distribution systems up through the water meter are typically regulated by state or provincial drinking water agencies.

Forty-eight U.S. states have legislation, regulations or policies requiring drinking water system components to comply with, or be certified to, NSF/ANSI 61.

Eleven Canadian provinces/territories require drinking water system components to comply with the requirements of NSF/ANSI 61.

Get more information and see a comprehensive map of the U.S. states and Canadian provinces/territories that require NSF/ANSI 61.
