Part 2 - Making and Testing Concrete Beams (Post tensioned/Non-post tensioned)

This is us constructing 2 beams and cracking them in the concrete lab as part of our internal assessment. Both beams were constructed identical to each other with same amount of reinforcing. Only difference being one was post-tensioned while the other wasn't. We wanted to see the difference in failure between the two.

in a day you had hard concrete....?

@ady0003 hehe.. not quite, "Day 2" on the video means the 2nd day in the lab. We made the beams and cured them in a water bath for 20 days (ideally should have been 28 days but were running out of time) before testing

What were the final figures on the breaking point of tension vs non-tensioned?

@jonr5000 I had to dig up the old report for this, the tensioned one failed at 16.5kN and the non-tensioned one at 13.8kN, we expected the results to be further apart originally
