DCP Concrete Mix Design
Don Construction Products — Concrete Mix Design Report
Where is this mix design filed?
Choose the project and area first. Every design you save and every report you generate is filed there, numbered, on your Design Desk.
You have no projects on your Design Desk yet. Create one here: its typical areas are set up for you.
If you skip, you are asked again before you save or generate a report. Nothing you enter is lost.
Done
The report is filed on your Design Desk with the design beside it. Take it from there.

Aggregate data
Enter the blend ratios, physical properties, and sieve analysis for each aggregate type.
Blend ratios & physical properties
How to fill this tableEnter the proportion (%) of each aggregate in the total blend. Ratios must sum to 100%. Specific gravity and absorption are from lab testing. Moisture is the field moisture content at time of batching.
| Aggregate type | Ratio (%) | Sp. gravity | Absorption (%) | Field moisture (%) |
|---|---|---|---|---|
| Sum of ratios | 100.0% ✓ | |||
Maximum aggregate size
Nominal maximum aggregate size (D) — the reference size for the gradation target curve.
mm
Gradation curve
The combined aggregate gradation should fall within the shaded specification band.
Combined gradation curve
Orange shaded zone = specification limits. The bold orange line is your combined gradation.
