What is mix design?
Getting the perfect mix for your project means finding the right balance between economy and requirements for placeability, strength, durability, density, and appearance. A mix design is determined by the proportions of course aggregate (stone), fine aggregate (sand), cement and water in a particular mix of concrete.
What are the mix applications?
Mixes are typically designated to meet 28 day psi compressive strength, water/cement ratio, slump, and air requirements as specified.. Mixes rated at 2,500 psi, for instance, are easy to pour and work, but offer limited strength. So, this mix is preferred for flatwork like sidewalks. 3,000 and 3,500 psi mixes are suited for flatwork, footers and some foundations. For pouring slabs on a grade and for walls the added strength of a 4,000 psi mix is needed. Finally, 4,500 and 5,000 psi mixes provide exceptional strength when needed.
What are concrete additives?
Often Boxley will recommend using a chemical additive in a mix to improve its overall properties. These include:
| Air entrainment | helps prevent freeze/thaw cracking |
| Fly ash | common additive to the cement portion of the mix |
| Water reducer | gives concrete more workability without weakening the mix |
| Superplasticizers | added at job site by a Boxley technician to improve workability |
| Retarder | slows the curing process when delivering over greater distances or to give the contractor more time to work the concrete |
| Accelerators | are added to concrete either to increase the rate of early strength development or to shorten the time of setting, or both |
| Fiber additives | are added to fresh concrete to protect against plastic shrinkage cracking and are also used for reinforcement |
Quality Control
To ensure the concrete we deliver meets a builder' specs, Boxley concrete technicians frequently test our mixes at the point of delivery. At the plant we use the latest high-tech control systems to be sure that every truckload in a delivery is consistent.
