How to calculate the amount of epoxy anchoring adhesive?


The formula for the amount of glue: the amount of planting glue W=Π×r2×h×2/3

Where W represents the amount of glue used (ML); r-drilling radius (cm); h-drilling depth (cm)

For example: ∮20 steel bar, drilling diameter 24MM, depth of 15D is 30CM,

Amount of glue for planting bars (ML)=3.14×(1.2CM×1.2CM)×2/3×30CM



The formula is too complicated, so Horse developed a tool that can calculate the amount of glue.


Just enter a few data, you can easily get the amount of glue
