Common Strength Ranges
Residential Slabs
Typical residential slabs use mid-strength mixes appropriate to load and exposure.
Driveways and Walks
Exterior slabs generally use air-entrained mixes for freeze/thaw durability.
Structural and Commercial
Higher-strength and specialty mixes may be specified by plans.
Air Entrainment
Exterior concrete in Illinois should typically be air entrained to resist freeze/thaw damage.
Aggregates and Admixtures
Aggregate size and gradation affect strength and finishability. Admixtures adjust setting time, workability, and other properties.
Frequently Asked Questions
What does concrete strength (PSI) mean?+
PSI is the pounds per square inch of compressive strength the mix is designed to reach, typically measured at 28 days.
What is air entrainment?+
Tiny air bubbles in the mix that give water somewhere to expand during freeze/thaw cycles, reducing surface damage.
