3. Mechanical behavior assessment
At this stage, the compression strength was the mechanical
property analyzed because it is the most required for this context.
Meanwhile, good compressive strength is also an indicator of good
impact and abrasion capacities.
3.1. Sample preparation and test equipment
The compressive strength of both corn cob and expanded clay
concrete was assessed with cubic specimens of 15 cm edge length.
In both cases, a weight ratio of 6:1:1 (i.e. lightweight
