Tips for Ordering Concrete
Quality – Concrete is a perishable product and should be treated as such. Time, weather conditions including a temperature of the concrete along with ambient temperature and wind speed can affect concrete. Talk with our representative about what you are pouring and how long you anticipate the pour to take. Typically, the concrete should be poured within 1 hour of batch time. Chemicals are available to retard or accelerate set times.
Quantity – Measurements can frequently be incorrect due to surface ground elevation, so we highly recommend ordering a little extra. A good rule of thumb is to take your calculation and add 4% to 10% to the total to account for waste, spillage, over-excavation, settlement, spreading of forms, loss of entrained air or any other changes in volume. Concrete can be ordered in 1/4 yard increments with a minimum of 1 yard.
Slump – Slump is a measure of the consistency of the concrete. A 4-inch slump (the measure of the distance a wet concrete cone will fall) is typical. If you want more slump you may want to speak with a technical representative to discuss your specific needs. He can prescribe a mix design specifically for your project without compromising quality. Adding just 1 gallon of water per cubic yard can decrease compressive strength 150 to 200 psi, and increase shrinkage by 10%. This is especially a problem for concrete that might be exposed to freezing and thawing conditions.
Strength – Strength is most commonly measured by the designed compressive strength in pounds per square inch (psi) of a hardened cylinder of concrete. Typical ready-mix concrete comes in strengths.
Entrained Air – Entrained air is microscopic bubbles of air primarily used to increase workability of concrete when placed and the durability of the hardened concrete to freeze-thaw conditions. Exterior slabs in our climate may or may not have air entrainment dependent upon their specific application.
Other Supplies – Do you need aggregate (stone or gravel) for the project? Do you have the concrete tools that you need? Our professional customer service representatives and our Concrete Store Representatives can help you make sure you are prepared, just call 229-888-9199.
Concrete Washout – You will need to provide a washout area for the truck after it is finished pouring the concrete. This should be a contained area that would not allow liquids to seep into surrounding areas. A wheelbarrow or other container is often the easiest to supply.
