Q: Can self-consolidating concrete be used for tilt-up panels? What does the finish look like, and are plastic shrinkage cracks a problem?
In February 2009, Concrete Construction magazine and Scurto Cement Construction Ltd., Gilberts, Ill., joined forces to conduct a field study focused on curling and shrinkage in warehouse floor slabs.

The WOC is the one-stop shop that involves everything relative to concrete.
Six months ago Scurto Cement, Elgin, Ill., along with several companies that contributed products, constructed a warehouse in the Chicago area. As one of the nation's largest floor contractors, Scurto searches for ways to reduce long-term shrinkage and curling in its floors.
A couple of years ago, Concrete Construction editors discussed the possibility of conducting a field test involving shrinkage and curling in warehouse floors. An excellent idea with plenty of potential to impact the industry, although one key ingredient was missing—a warehouse floor.
The idea of initiating a field test to learn more about shrinkage and curling in warehouse floors is something that Concrete Construction magazine has considered for the past couple of years. So when Greg Scurto, president of Scurto Cement, Gilberts, Ill.
Reentrant corner cracks can ruin an otherwise impressive slab, whether it be decorative concrete, an industrial slab, a high-end exposed retail floor, or your backyard patio.

Industrial slabs need contraction joints to minimize random cracking. The most effective and efficient method of producing contraction joints is by sawcutting.

As one thinks back over the past 30 years, a number of innovations have significantly changed and improved the way we do things. In concrete construction, the "early-entry" saw has significantly changed and improved the way concrete floors are constructed
Macro polymeric fibers (MPF) have been used in numerous slabs on ground providing amazing performance for various applications.
When it comes to choosing the “right tools for the job,” the prudent contractor does his homework before getting in over his head. Today, choosing tools incorrectly, or not including the needed tools in the bid for a project, can financially sink a contractor when repairs are needed because of poor...
We've all heard the saying, “With concrete there are two guarantees: it will get hard and it will crack.” How hard it will get and how much it will crack has a lot to do with the amount of water and cementitious material used to make it.
Water is an essential ingredient in concrete, but uncontrolled excessive moisture can create a whole host of problems with concrete floor slabs.
There are many opinions floating around as to the benefits, or lack thereof, of reinforcement in slabs on ground. Not all reinforcement works the same way. To be able to understand the potential benefits and negatives of any particular reinforcement system, one has to understand how that system...

Usual considerations include such things as the strength of the concrete, the finish, and the spacing between joints. But there are other issues: durability, shrinkage, curling, moisture vapor transmission, and maintenance, to name a few.

I am about to install a 10,000-square-foot floor and the owner believes that wet curing the floor will result in no curling. Is this true?
Some Midwest ready-mix producers report there have been more problems associated with plastic shrinkage in concrete this past spring.
