Concrete Mix Design (ACI 211)
Design a normal-weight concrete mix per ACI 211.1-91 absolute-volume method. Inputs: slump, nominal max aggregate size, air entrainment, water-cement ratio w/c, fineness modulus of sand, and dry-rodded coarse-aggregate density. Outputs the per-cubic-meter masses of cement, water, fine and coarse aggregate plus the mass ratio.
Quick start
Call this tool from your code in three languages.
curl -X POST 'https://api.elysiatools.com/en/api/tools/concrete-mix-design' \
-H 'Content-Type: application/json' \
-d '{"slump":"75-100","maxSize":"19","air":"non-entrained","wcRatio":0.45,"finenessModulus":2.7,"caDensity":1600,"decimalPlaces":2}'API reference
Send a POST request with your inputs as JSON. File parameters require a separate upload first.
Endpoint

| Name | Type | Required | Description |
|---|---|---|---|
| slump | select | No | — |
| maxSize | select | No | — |
| air | select | No | — |
| wcRatio | number | Yes | Mass ratio of water to cement. Typical range 0.35–0.65. |
