How Strong is CSA Concrete? – Deflection Test Lightweight Garden Box Panels

By May 10, 2020May 18th, 2020One Comment

I test the deflection strength of CSA concrete garden box panels under a point load. These panels link together to make long lasting rot-proof garden boxes. I test 1 lightweight panel made from CSA Mortar Mix. These panels were made in Part 4 of my Garden Box series. I load the panels with weight until their breaking point.

 

See the Youtube Video and download the Plans.

Background for this Video

I’ve had many requests to test the strength of my garden panels. It took some to figure out the best way to go about this. With limited equipment it can be difficult to get measurable results. I decided to take a non-scientific general approach and try so fairly basic tests to see how the panels held up to weight that either approached their breaking point, or past it. Have a look at the video and please some comments and questions.

I recommend a heavier gauge mesh in any new panel castings

Now I have to replace the broken panel with a new one. Dang!

Thanks for looking!!
