Concrete Mix Design Quote Checklist
Compare concrete mix design quote details including PSI, slump, aggregate, air entrainment, fiber, pump mix, admixtures, exposure, delivery, and warranty terms.
A concrete mix design quote checklist helps you ask what type of concrete is being priced, not just how many cubic yards are needed. PSI, slump, aggregate, air entrainment, fiber, pumpability, color, admixtures, weather exposure, and delivery timing can all change the supplier quote.
Use the Concrete Cost Calculator for quantity and cost planning. Then compare supplier terms with the Ready-Mix Concrete Supplier Quote Checklist. For bid review, enter mix assumptions into the Concrete Quote Reviewer.
Competitor pages often cover mix ratio or PSI calculators. This checklist keeps the buying decision visible: what mix is actually quoted and why.
Quick answer
A concrete mix quote should identify:
mix quote =
strength or PSI
+ aggregate size
+ slump and workability
+ air, fiber, admixtures, color, or pump mix
+ exposure, finish, delivery, and warranty assumptions
Do not treat a generic mix name as enough information for a job that has structural, code, freeze-thaw, pump, decorative, or inspection requirements.
Mix quote inputs
| Input | Why it matters | Quote question |
|---|---|---|
| PSI / strength | May be specified by plans, code, or contractor. | What strength is quoted? |
| Aggregate size | Affects finish, pumping, and thin sections. | What aggregate is included? |
| Slump | Affects workability and placement. | What slump is quoted and who can adjust it? |
| Air entrainment | Important for some freeze-thaw exposure. | Is air included or required? |
| Fiber | May be an add-on or alternate. | Is fiber included, optional, or excluded? |
| Pump mix | Pumping can need coordination. | Is the mix suitable for the planned pump? |
| Admixtures | Weather or performance changes cost. | What admixtures are included? |
| Finish | Decorative or hard-trowel needs differ. | Does the mix match the finish plan? |
For pump planning, use the Concrete Pump Cost Calculator Guide.

Project mix questions
| Project | Mix question to ask |
|---|---|
| Driveway | Is the mix appropriate for vehicle loads and local exposure? |
| Patio | Does the mix fit broom, decorative, or sealer plans? |
| Garage slab | Is the finish plan compatible with the mix and vapor conditions? |
| Footing | Does the mix match plans, inspection, and placement method? |
| Pool deck | Is wet-area finish, exposure, and traction considered? |
| Pump job | Has supplier and pump contractor agreed on mix requirements? |
This page is not a structural mix design. Confirm specifications with qualified professionals when the project is code-sensitive or structural.
Mix quote red flags
| Red flag | What to ask |
|---|---|
| "Standard mix" only | What PSI, aggregate, slump, air, and admixtures are included? |
| Pump planned but mix not checked | Has the pump contractor approved the mix? |
| Finish sensitive job | Does the mix fit stamped, exposed, trowel, or broom finish? |
| Freeze exposure ignored | Is air entrainment required locally? |
| Fiber assumed | Is fiber included, optional, or separate from reinforcement? |
| Water adjustment unclear | Who can add water and how is it documented? |
FAQ
What is a concrete mix design quote?
It is the supplier or contractor quote detail that identifies the concrete being ordered, including strength, aggregate, slump, air, fiber, admixtures, and delivery assumptions.
Is PSI the only mix detail that matters?
No. PSI matters, but slump, aggregate, air entrainment, fiber, pumpability, finish, exposure, and weather can also affect the correct quote.
Can I choose the mix myself?
For simple non-structural planning, you can ask better questions. For structural, code, permit, engineered, or safety-sensitive work, use qualified local professionals.
Does this replace supplier advice?
No. Confirm mix, slump, additives, delivery timing, testing, warranty, and specification requirements with your supplier and qualified professionals.
Next step
After the mix is quoted, keep the delivery record with the Ready-Mix Delivery Ticket Checklist and compare full delivered totals in the Ready-Mix vs Bags Calculator.
