Apakah Pengiraan Konkrit?
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
Papak segi empat tepat
V = L × W × T. Patio, jalan masuk, lantai.
Papak Pekeliling
V = π × r² × T. Teras bulat, asas.
Lajur
V = π × r² × H. Tiang, tiang bulat.
pijak
V = L × W × D. Tapak asas.
dinding
V = L × H × T. Dinding konkrit, penghadang.
Penukaran volum
Convert between cu ft, cu yd, and m³.
Understanding Mix Ratios
| Ratio | simen | pasir | Agregat | guna |
|---|---|---|---|---|
| 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 |
Volume Conversions
1 cubic yard = 27 cubic feet
1 cubic foot = 0.0283168 cubic meters
1 cubic yard = 0.764555 cubic meters
Nota Penting
- Add 5–10% extra to account for waste, spillage, and uneven surfaces.
- Round up cement bags to the nearest whole number when purchasing.
- Ela padu ialah unit standard yang digunakan oleh pembekal campuran sedia di AS.
- Untuk projek struktur, rujuk jurutera berlesen untuk mendapatkan campuran dan tetulang yang betul.
