Ready-mix concrete Ready-mix concrete is concrete manufactured at a batching plant and delivered to a job site in a mixer truck. It is produced to a specified mix design for strength, durability, and consistency.
Ready-mix concrete is widely used for sidewalk, curb, driveway, and pavement construction because the ingredients are measured under controlled conditions before delivery. Contractors order a mix that meets the project's required compressive strength and performance characteristics. In NYC, using the specified ready-mix helps ensure finished concrete complies with applicable construction standards and performs reliably over time.
Frequently Asked Questions About Ready-mix concrete
What is ready-mix concrete?
Concrete batched at a plant to a specified mix design and delivered to the job site in a mixer truck.
Why is it used for sidewalks?
Because ingredients are proportioned under controlled conditions, giving consistent strength and workability that site-mixed batches struggle to match.
What should be specified when ordering?
The required compressive strength, air entrainment for freeze-thaw exposure, slump range, and any fiber or admixture requirements from the project specification.
Does the delivery ticket matter?
Yes. It documents the mix design and batch time, which is useful evidence that the concrete placed met the specified requirements.
