A Short History of Concrete Pipe by the PCA

Posted by Hill and Griffith Company on Feb 14, 2019 9:00:29 AM

Concrete pipe has a well established history and reputation for being a long lasting, serviceable material.

Concrete-Form-Release-Agent-1.jpgThe Cloacae Maxima, built in about 180 B.C. as part of Rome's main sewer system, was constructed mainly of stone masonry and natural cement concrete. More than 2,000 years later, portions of the concrete sewer are still in use.

Modern day concrete sewer systems emerged during the mid-19th century when the public became conscious of the need for sanitation to control the spread of disease. The earliest recorded use of concrete pipe in the United States is a sewer installation built in 1842 at Mohawk, N.Y. Other New England cities followed suit and installed concrete pipelines in the second half of the nineteenth century. Many of these concrete pipelines are still in use today.

Milestones in development include the production of the first reinforced pipe in 1905, the invention of prestressed pipe in the 1930s, and the manufacture of the first steel-cylinder prestressed pipe in 1942. 

Sizes can range from four inches up to 17 feet in diameter. Although pipe can be manufactured in a variety of shapes, there are five standard shapes: circular, horizontal elliptical, vertical elliptical, arch, and rectangular. The pipe shape selected for a project depends on the topography of the site, importance of hydraulic and structural efficiency, erosion and deposition in the stream channel, and cost. Most often, the preferred pipe shape is the one that will alter the natural drainage flow the least.

Concrete-Form-Release-Agent-2.jpgFive Methods of Producing Pipe Made of Concrete

As with all concrete products, the basic materials are portland cement, aggregate, and water. There are five basic methods of producing pipe. Four methods -- centrifugal/spinning, dry cast, packerhead, and tamp-entail using a dry concrete mix. The fifth method, wet casting, uses a high-slump concrete mix. Wet-cast concrete mix usually has a slump less than four inches and is most frequently used for manufacturing large diameter pipe.

These types of pipe serve as a conduit material for irrigation, water supply lines, sanitary sewers, culverts, and storm drains. Culverts, usually made with arch-shaped concrete, are used to carry water under highways in non-urban areas. Storm drain systems for cities and towns are becoming more important as communities become larger and more densely populated. Recent major floods and the resulting damage only emphasize the need for efficient drainage systems.

Subsurface drainage carries away water below the surface of the pavement. This water reduces flow support capacity of the base and subgrade material causing potential damage to roads, airport runways, and building foundations. Many farm fields depend on proper underground drainage for their cultivation. Thousands of square miles of otherwise arid land rely on concrete irrigation pipe to supply water for farmland. Additionally, most of the large cities in the United States a pipe system made of concrete to transport their water supply.

(From the Portland Cement Association's web site.The PCA is a powerful and vocal advocate for sustainability, jobs creation, economic growth, infrastructure investment, and overall innovation and excellence in construction throughout the U.S.)

Prevent Concrete Bughole Surface Void Formation

Posted by Hill and Griffith Company on Jan 17, 2019 12:20:14 PM

Using concrete as an architectural material has brought the quality in surface appearance to an important consideration.

One of the problems affecting the surface aesthetics of concrete are bugholes. Bugholes are surface voids from the migration of mostly entrapped air to the fresh concrete form surface, mostly in the vertical plane.

preventing_bug_holes

Photo from Precast Inc. Magazine's May/June 2014 issue.


During setting, the shrinkage of the concrete forces entrapped air voids and excess water out of the mix. Water migrates upward due to density and becomes bleed water. The air bubbles seek pressure equilibrium and when in a vertical form, that's to the interior surface. These bubbles need to be directed vertically to the surface of the concrete form. Bugholes are found in the upper portion of the concrete structure or at angled form surfaces as a result of accumulation of escaping air along the height of the structure. They are primarily an aesthetic problem for exposed surfaces.

Causes

The biggest cause of bugholes is improper vibration. Consolidation through vibration, sets the bubbles into motion and sends both entrapped air and excess water to the surface.

Bughole formation can also be caused by the form material and the type of form release used.

When a chemically reactive form release agent is used, a nonviolent chemical reaction takes place when fatty acids react with free lime on the surface of fresh concrete. This reaction results in the formation of a metallic soap, a slippery material that allows air bubbles to rise along the vertical surface. This “soapy” film also prevents the hardened concrete from adhering to the forms during stripping.

Thicker coatings on forms are typical of the older barrier-type materials, like heavyweight used motor oil, vegetable oils, diesel fuel and kerosene. Barrier type release agents are less expensive than chemically reactive agents, but they are not generally recommended for reducing SCC bug holes."

Mix design can also contribute to bughole formation. A sticky or stiff mixture that is hard to consolidate can increase surface void formation.

Reduce Bugholes

Solutions

The vibrator should penetrate the previous lift and work the entrapped air towards the form and then up the sides. More vibration is necessary with impermeable forms, to move the air voids to the free surface of the concrete.

Flowing mixtures reduce bughole formation. Concrete that limits excessive fine aggregate, has the proper cement content, and uses admixture for increased flow contributes to bughole reduction. Self-consolidating concrete is becoming increasing popular for precast to improve surface quality.

Bugholes are not detrimental to structural concrete. But, with the increased use of concrete in finished construction, surface quality is important. Through careful selection of materials, quality workmanship, and dutiful supervision, surface voids can be minimized.

"Form Release Agents," Technical Q&A from the American Concrete Institute Review

Posted by Hill and Griffith Company on Jan 11, 2019 5:05:58 PM

ACI committees, membership, and staff have answered common questions on a variety of concrete related topics

Form release agents

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?

American Concrete Association Form Release


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”.

What is concrete release agent form oil made of?

Posted by Hill and Griffith Company on Jan 3, 2019 1:56:40 PM

There are three types of concrete release agents. They are very different in their cost, use and composition.

Concrete form release agents prevent the adhesion of concrete to the forming surface, usually plywood, steel or aluminum. In this application, there are three types of release agents available: barrier, reactive and water based.

"The thinner the better," is the best application motto for concrete form releases.


• Barrier oil based release agents develop a physical film between the form and the concrete.

• Reactive release agents are chemically active and work by the process of a chemical reaction between the release agent and the free limes available in concrete. A soapy film is created which prevents adhesion. There is generally little to no residue or unreacted product left on the forming surface or concrete which provides for a cleaner release.

• Water-based release agents are a result of more focus on health, environment and safety issues. This has resulted in the development of new technologies primarily focused on water-based formulations, with the movement being away from petroleum-based products.

Learn more by reading Bob Waterloo's article, "How Safe (and Legal) is Your Concrete Form Release Agent?" Which ran in PRECAST INC Magazine. Bob Waterloo is the distribution manager, the Hill and Griffith Company. For additional information, contact him at bwaterloo (at) hillandgriffith.com.
