What's this calculator used for?
This free concrete mix calculator helps materials engineers and temporary works designers calculate the approximate maximum concrete pressure applied to the panels of their formwork system and estimate the number of ties needed between the formwork panels considering pouring temperature, admixtures, retarders, ggbf and pfa content.
