Brazilian Test - Tensile Failure of Concrete in Slow Motion


This video shows the Brazilian test, which is designed to measure the tensile strength of concrete. 

Tests such as this one are the standard way of measuring the tensile strength of concrete. This test shows that:
  • - concrete is brittle in tension 
  • concrete has a low tensile strength compared to its compression strength 
  • application of a compression force can cause cracks to open up in a perpendicular direction

At the end of the video a graph of vertical load versus vertical deflection shows the point at which brittle failure occurs.
