Frequently Asked Questions (3)
Q1. What is the purpose of the RC beam?

The RC beam is simply supported and subjected to flexural loading in order to simulate loading on actual RC structures such as bridge girders, beams and slabs. 

Roughness equipment is used on the tension surface to obtain a suitable face and to have as much friction as possible with the CFRP sheet. 

This is because the substrate must be sound, dry, clean and free from laitance, ice, standing water, grease, oils, old surface treatments or coatings and all loosely adhering particles.
