Handy guide on factors to multiply per cubic on different concrete class mixtures. Just multiply each factor to the total volume (in cubic meter) and you’ll get the needed amount of cement (40Kg/bag), sand (cu.m.) and gravel (cu.m.).
| Class C (2,000 psi) | ||
| Cement | 5.634 | Bags |
| Sand | 0.4794 | cu.m. |
| Gravel | 0.898 | cu.m. |
| Class B (2,500 psi) | ||
| Cement | 7.399 | Bags |
| Sand | 0.486 | cu.m. |
| Gravel | 0.8856 | cu.m. |
| Class A (3,500 psi) | ||
| Cement | 8.799 | Bags |
| Sand | 0.5724 | cu.m. |
| Gravel | 0.856 | cu.m. |
| Class AA (4,000 psi) | ||
| Cement | 11.729 | Bags |
| Sand | 0.475 | cu.m. |
| Gravel | 0.8344 | cu.m. |
The following factors were already added an average wastage add-ons of around 5% to 8%. This numbers should help average Filipinos to know draft amount of materials needed for minor concreting works.
