What this calculation does not cover

  • A volume divided by an area gives an average thickness, and concrete is not laid to an average — slabs and toppings are finished to a level or a fall, so every low spot underneath is made up out of the same fixed tonnage. Thinning the rest to cover it is not open to you: the largest stone in the mix sets a minimum placeable depth and any steel still needs its cover buried, so a short volume shows up as area not reached.
  • Every yard this returns depends on the density behind it, and the one used is for normal-weight concrete. Run a lightweight mix through it and the volume comes out low — the same tonnage is more yards and more coverage than this shows — so any depth or area check should take the density off the mix design.
  • The volume this returns has to be prepared and waiting rather than stored. Ground-bearing work needs the formation trimmed to level and edged before the trucks arrive, and concrete stiffens within hours, so where the volume goes in as more than one layer or bay each has to be placed while the last will still take a vibrator — past that a cold joint runs through the element.

Working back from a concrete weight to a volume comes up in structural checks: how much a proposed slab adds to a floor, or how much concrete a crane can lift in a skip. The density used is for normal-weight concrete, and lightweight mixes differ considerably, so a structural calculation should use the specified mix density rather than a general figure. Formwork and falsework design in particular is driven by concrete's weight and its fluid pressure while wet, which is a separate and larger consideration than the finished load.

Frequently asked questions

Why does formwork need to resist so much?
Because wet concrete behaves as a fluid and exerts lateral pressure that increases with pour rate and depth. That pressure, not the finished weight, is what governs formwork and falsework design.
How much can a crane skip hold?
Whatever volume its rated weight capacity allows at about 2.03 short tons per cubic yard, which is less than its volume suggests, because concrete is dense. Check the skip's rated capacity in weight against the converted figure rather than filling it to the brim.
Does concrete weight affect the structure below?
It is a primary dead load, and on a suspended slab or an existing floor it is the first thing to check. Adding a screed or topping to an existing floor needs the structure verified rather than assumed.
Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.
