What will adding one gallon of water do?
- Increase slump one inch
- Strenth will be reduced by 150-200 PSI
- Air content can be reaised ½ -1% reducing strength an additional 150-200 PSI
- Plastic shrinkage cracking potential will increase 7%
- Freeze/Thaw resistance is reduced
- The chance of scaling will greatly increase
- Durability will be greatly reduced
Why choose Sequatchie Concrete Service?
Our courteous, efficient, well-trained personnel are dedicated to providing you with exceptional service and quality products.
We maintain a modern computerized dispatch center as well as over 30 automated batch plants, including " on site" portables, enabling us to consistently produce quality concrete.
We maintain a "state of the art" fleet of equipment, with over 950 trucks utilizing GPS technology to meet the ever increasing demands of the construction industry.
We are able to batch mix designs to the requirements of the individual customer or design a mix to meet the specific requirements for any application.
How long until I my place my recently poured concrete into service?
Typically, concrete may be placed into service once it has achieved its design strength. Design strength is a measurement, of resistance to compression in pounds per square inch, at a certain age (28 days is the industry standard). Eagle Ready-mix has designed their concrete to meet or exceed design strengths within 7 days under ideal conditions (65 degrees F. ,low wind velocity, and high humidity) however we would still strongly recommend you wait 14 days to place your concrete into service.
What is the difference between cement and concrete?
Cement, or Portland Cement, or Portland as it is sometimes called refers to a product obtained by pulverizing clinker consisting primarily of hydraulic calcium silicates; usually interground with calcium sulfate. Cement constitutes between 7 and 15% of the volume of concrete and forms the binding paste when mixed with water. Concrete is the combination of cement, water, aggregates and sometimes admixtures.
How is concrete batched so that every yard is the same from load to load?
Sequatchie Concrete Service utilizes state of the art computer batching systems to ensure consistency from yard to yard or load to load. The computers measure and weigh each ingredient and insure that those measurements are within a certain tolerance.
What does air do for concrete?
Air is purposely incorporated into concrete (through the use of a liquid admixture) to increase its durability to freeze-thaw cycles. The air void system allows expansive alkali solutions in concrete “room to grow” during periods of freezing.
Why is it not recommended to use a steel trowel on exterior concrete exposed to freeze-thaw cycles or deicing chemicals?
A steel trowel finish "closes up" the surface of the concrete, virtually destroying the air void system, which may lead to surface defects in the future. A standard practice should be to; “under finish - and over cure”.
If you produce concrete by weight, how do you sell it by volume?
Although concrete is produced (batched) by weight, the conversion to volume is a simple calculation once the specific gravity values for all ingredients are known to calculate the absolute volume each will occupy in a unit volume of concrete. Specific gravity is the relationship between the weight of a known volume of material and and the weight of an equal volume of water.
Take your measurements and then go to our Concrete Calculators page. We recommend you order extra to compensate for concrete that remains in the truck or pump.
How do I decide if I need a pump or not?
You have three choices for getting the concrete from our ready-mix truck to your project:
- Place it using the truck's chutes, which extend approximately 16' from the back of the truck. You will need about 14' clearance and about 12' width for the truck.
- Use a pump truck. We will gladly recommend companies that we use in your local area.
- Wheelbarrow.
If there is not enough room for a truck to get to your project, you will need to pump it or wheelbarrow it. If you decide to use a wheelbarrow, please keep in mind that one cubic yard of concrete weighs roughly 4,000 pounds and that you will most likely incur some unproductive time. We allow for 45 minutes to an hour to unload a truck. Any additional time is billed at $50 per hour.
In addition, please be advised that Sequatchie Concrete Service requires all our customers to sign a waiver before leaving the public road, relinquishing SCS from liabilty for any porperty damage that may occur.
