a bamboo reinforced concrete beam was made in a lab an I'm supposed to answer these questions:

How did the workability vary from your group’s plain concrete results and explain why  

How did your cube compressive strength vary from your other group’s results and suggest why  

How did the compressive stress in the concrete at failure in flexure compare to the cube compressive strength? What does this imply?  

List five ways in which the load which this beam carries could be improved  

Results can be found here (group 2- shredded rubber concrete):
