Lightweight Concrete Showdown - Now that all of our full strength and lightweight concrete test blocks have finished curing, we can test them for a strength to weight ratio to find out just how strong lightweight concrete can be. 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 withstand before breaking.

In order 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.

Watch as weight gets added to this 3:1 vermiculite to portland cement block and see just how much it handles before it breaks. The results of this strength to weight ratio testing will be compared to the full strength control block as well as the other lightweight concrete test panels. Do any of the lightweight mix recipes hold up to the results of the full strength block? Stay tuned to find out how each panel stands up the the weight of testing.
