Calculation method
Calculation method
Geometric joint void (litres)
sum(r[0]*r[1]*r[2]/1000 for r in a)
Purchase mortar volume (litres)
sum(r[0]*r[1]*r[2]/1000 for r in a)*(1+b)
Whole batches
ceil(sum(r[0]*r[1]*r[2]/1000 for r in a)*(1+b)/c)
Symbols and units
- a
- JSON Joint groups [length m,width mm,depth mm]
- b
- Supplied waste fraction
- c
- Usable batch volume (litres)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Calculation steps and notation
sum(list) adds all entries in the list.
Assumptions & limits
Assumptions & limits
- Rectangular measured repointing voids with no overlap at intersections; supplied waste and yield. No mortar specification. Supported limits: All numeric inputs must be finite. Only the explicitly described mathematical scenario is supported.
