Driving on asphalt is like driving on flat tires. They both increase rolling resistance and decrease miles per gallon. According to a recent study by the Massachusetts Institute of Technology, concrete pavement‘s greater stiffness reduces vehicle fuel consumption by as much as 3 percent. That can add up to over 270 million barrels of crude oil and $15.6 billion saved in a single year. It’s yet another way that concrete keeps us rolling.

Traditional steel, i.e. wire mesh and rebar have been used for decades as a secondary reinforcement for concrete slabs. The purpose of the steel is to help hold broken pieces of concrete tightly together after the concrete has cracked. However, many times the steel is placed directly on the subgrade rendering the reinforcement useless. The Wire Reinforcement Institute states: “Only when the reinforcing steel is properly selected, placed and supported can its use be recommended or its cost warranted.”
Macro synthetic fibers were introduced in the year 2000 as an improved alternate to traditional steel as a secondary reinforcement for slabs-on-grade and composite metal-decks. Macro fibers are typically defined as fibers that are longer in length, up to 2 ¼”, and dosages ranging from 3.0 lbs. to 7.5 lbs. per cubic yard of concrete. The macro fibers are added directly into the concrete mix providing for a three dimensional reinforcement, whereas steel reinforcement must be placed before the placement of the concrete. The Wire Reinforcement Institute also states: “It is impossible to hook fabric uniformly to desired location after the concrete has been placed.”
Macro fibers have been used in numerous applications worldwide to replace traditional steel in projects ranging from parking lots, commercial and industrial floors to composite metal-decks.
Benefits to using macro synthetic fibers are: reduction of plastic and hardened concrete shrinkage cracking, improved impact resistance and residual strength. They are also non- corrosive unlike wire mesh and rebar. The fibers are also a considerable cost-savings vs. conventional labor-intensive steel reinforcement.

Yay it's March finally, surely spring can't be far off now. Time to start getting ready for the new construction season. For contractors it's a great time to make sure all of your equipment is clean and repaired if needed. If you take the time to make sure everything is in working condition now, it will save you time and money later on when you need it and it works.
It's also a great time to start calling some of the customers you've done work for in the past and see if maybe they are thinking about having something else done or know of anyone that is looking to have something done. Plus it's a great time for you to get feedback on their impression of your workmanship. Don't under estimate the power of unhappy customers to ruin your business. There use to be a guideline if you lose 1 customer, you loose 250 by the time they tell everyone they know. With todays social media I'm sure that number is much larger now since its so much easier to pass the word around, don't let a simple misunderstanding become a major problem.
Spring is a great time to brush up on new techniques that have come out and maybe try to learn some new products that you can add to your resume. There are lots of places you can take a class or two like http://www.deco-cretesupply.com/ for example.
Spring is the time for renewal and staring over so be sure you're ready to start the new year with a fresh outlook.

You know the old Boy Scout motto about being prepared—failing to be prepared is preparing for failure. Same goes for concrete work in general, but especially when cold weather comes on unexpectedly. To handle the cold, have everything you might need on hand and review these tips:
Frozen ground—NEVER place concrete on frozen ground or onto ice or snow. There are a couple of problems with this. First, frozen ground will settle when it thaws, cracking the concrete. Second, when the ground is cold, the concrete in contact with it will be cold and will set more slowly. You can even get crusting, with the top part of the concrete set and the bottom still soft.
If the ground is frozen, you can thaw it using hydronic heat pipes and blankets (such as those from Ground Heaters), or electric blankets (check out Power Blanket).
Remove all snow and ice in areas where concrete is to be placed. Also remove any standing water that could get mixed into the concrete.
Warm up anything that will come in contact with the concrete, including forms and any embedments, to at least 32°F. If it's not too cold and you cover everything with tarps the day before the pour, it will stay dry and warm enough. Keep tools in your truck or trailer.
Be ready with blankets, even if you don't think it will get that cold. Also consider whether you will need lights if the concrete sets more slowly than expected and the winter sun sets just as you're finally ready to start finishing.
There will be some heat loss from the ready mix plant to the job site. For a one-hour delivery time, the concrete temperature will drop about one-fourth the difference between the air temperature and the concrete temperature. So if the concrete's 65°F and the air is 45°F, in one-hour of travel it will drop 5°F and the concrete will end up at 60°F.
Concrete set time will slow dramatically when it's tempature reaches 50 degrees and will, for all intents and purposes stop when it's core temp drops to 40 degrees. Once the concrete has reached 500 psi, the risk of freeze/thaw damage is dramatically reduced.
Please remember that while using set accelerators such as calcium chloride may speed up the set time, they won't protect the new concrete from freezing.
