Mortar
Mortar is made with clay and heap of sand. The recipe for mortar calls for equal parts (1kg) of clay and heap of sand to make one mortar.
However, one clay is 2kg and one heap of sand is 20kg. Knowing this we can calculate the total clay and heap of sand needed to make the amount of mortar we want.
A simplified way of representing it is this.
- 1kg of clay is half of a full clay (2kg), or .5, so we will use .5 (1/2) for our formula.
- 1kg of heap of sand is one twentieth of a full heap of sand (20kg), so we will use .05 (1/20th) for our formula.
| Clay | |
|---|---|
| Value | Formula |
| Number | $\text{Number} = \text{Mortar Needed} \times .5$ |
| Kg | $\text{Kg}=\text{Number}$ |
| Heap of sand | |
|---|---|
| Value | Formula |
| Number | $\text{Number} = \text{Mortar Needed} \times .05$ |
| Kg | $\text{Kg}=\text{Number}$ |
For example…
2000 mortar will need 1000 clay ($2000 \times .5$) and 100 heap of sand ($2000 \times .05$). Kg is equal to the amount needed since the recipe calls for 1kg each of clay and heap of sand per mortar.
Notes
Keep in mind that kg and volume are two different things. Volume is said to be represented as liters for liquid, but volume for solid objects is not explained.
A bulk storage bin has a volume column. What you see in the volume column is not equivalent to kg. A heap of sand is 20kg but takes up 18.75 volume in a bulk storage bin. This is why if you have 100 heap of sand the kg is indeed 2000kg but the total volume is 1875.
