Wat is betonberekening?
Concrete calculation determines the exact volume of concrete needed and the required materials (cement, sand, aggregate) based on the selected mix ratio. Accurate calculations prevent material waste, control costs, and ensure proper project planning.
6 Calculation Modes
Rechthoekige plaat
V = L × B × T. Patio's, opritten, vloeren.
Ronde plaat
V = π × r² × T. Ronde patio's, funderingen.
Kolom
V = π × r² × H. Pijlers, ronde kolommen.
Voet
V = L × B × D. Funderingsfunderingen.
Muur
V = L × H × T. Betonnen muren, barrières.
Volumeconversie
Convert between cu ft, cu yd, and m³.
Understanding Mix Ratios
| Ratio | Cement | Zand | Totaal | Gebruik |
|---|---|---|---|---|
| 1:2:4 | 1 | 2 | 4 | General construction, foundations |
| 1:1.5:3 | 1 | 1.5 | 3 | Structural elements, higher strength |
| 1:3:6 | 1 | 3 | 6 | Non-structural, mass concrete |
| 1:2:3 | 1 | 2 | 3 | Heavy-duty, structural |
| 1:1:2 | 1 | 1 | 2 | Maximum strength |

1 cubic yard = 0.764555 cubic meters
Belangrijke opmerkingen
- Add 5–10% extra to account for waste, spillage, and uneven surfaces.
- Round up cement bags to the nearest whole number when purchasing.
- Kubieke yards is de standaardeenheid die door leveranciers van kant-en-klare mengsels in de VS wordt gebruikt.
- Raadpleeg voor structurele projecten een erkende ingenieur voor de juiste mix en versterking.
