What is the maximum strength of cub compress strength in one cub testing ?

  • First of all, we make the concrete cube at some mix proposition as M15, M20.
  • Then after one day the curing on concrete cube at 7days or 28days and we find out the compressive strength of concrete

Sampling of Cubes for Test :

  • Clean the mounds and apply oil.
  • Fill the concrete in the molds in layers approximately 5cm thick.
  • Compact each layer with not less than 35strokes per layer using a tamping rod (steel bar 16mm diameter and 60cm long, bullet pointed at lower end).
  • Level the top surface and smoothen it with a trowel.
