Watch as we put the next lightweight concrete block in our Lightweight Concrete Showdown to the test. We are testing the strength to weight ratio of a 2:1 perlite to portland cement test panel. After curing to its full strength for a full month it is ready to test to its breaking point! And we like to break things, for science of course.

We have made lightweight concrete panels, each 28 inches long by 1 inch thick, with different mix ratios and lightweight aggregates to find out just how much weight they can bear before cracks and fails. To compare lightweight concrete mixes based on strength performance, we first made and tested a regular (full weight) concrete / mortar control test block. Full strength concrete will be stronger than every lightweight concrete mix design but how close can we get the strength to weight ratio is very useful information.

Do any of the lightweight mix recipes hold up to the results of the full strength block? See the results of this strength to weight ratio testing and how it compared to the full strength control block as well as the other lightweight concrete test panels by watching the full Lightweight Concrete Showdown series:
