I test the deflection of several lightweight concrete garden box panels under a point load — to find out how strong is lightweight concrete. These panels link together to make long lasting rot-proof garden boxes. I test 4 lightweight panels made from Perlite, Vermiculite, Lava Rock with portland and CSA cement. Some broke and some didn’t.

How Strong is Lightweight Concrete? – Deflection Test Perlite Vermiculite
Background for this Video
I’ve had many requests to test the strength of my lightweight concrete 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 lease some comments and questions.

In the next episode I’ll test the strength of some aircrete panels. So that’s coming right up.
