We are developing some simple and not so simple calculators that will work out diy related things such as amount of sand, cement and ballast required to make concrete or mortar.
In the mean time the following tables should help;
| Mortar Mixing Proportions | |||
| Cement/Lime Mortar | Plasticized Mortar | Masonry Morter | |
| General Purpose Mortar | 1 Part Cement | 1 Part Cement | 1 Part Cement |
| 1 Part Lime | 6 Parts Sand/ plasticizer | 5 Parts Sand | |
| 6 Parts Sand | |||
| Strong Mortar | 1 Part Cement | 1 Part Cement | 1 Part Cement |
| Half Part Lime | 4 parts Sand/ plasticzer | 3 parts Sand | |
| 4 parts Sand | |||
| Mixing concrete by Volume | ||
| Type of Mix | Proportions | To Mix 1 Cubic Meter of Concrete you will need |
| General Purpose | ||
| Used in most situations including covered pads (excluding Garage Floors) | 1 Part Cement | 6.4 Bags (50Kg Bag) |
| 2 Parts Sand | 0.448 Cubic Meter | |
| 3 Parts Aggregate | 0.672 Cubic Meter | |
| 4 Parts Ballast | 0.896 Cubic Meter | |
| Foundation | ||
| Used for footings at the base of masonary walls | 1 Part Cement | 5.6 Bags |
| 2.5 Parts Sand | 0.49 Cubic Meter | |
| 3.5 Parts Aggregate | 0.686 Cubic Meter | |
| 5 Parts Ballast | 0.98 Cubic Meter | |
| Paving | ||
| Used for exposed slabs such as drives, parking areas or footpaths including Garage Floors | 1 Part Cement | 8 Bags |
| 1.5 Parts Sand | 0.42 Cubic Meter | |
| 2.5 Parts Aggregate | 0.7 Cubic Meter | |
| 3.5 Parts Ballast | 0.98 Cubic Meter | |
