I produced some un-stabilized, lime-stabilized, and cement-stabilized compressed earth blocks with my dirt in Colorado Springs and wanted to see how the lime-stabilized (both 8% and 16%) blocks held up in a water-submersion test. I was overall impressed with the way they held up and was glad that the 8% lime blocks did as well if not better than the 16% lime blocks. Next I'm going to produce some 6% and 4% lime-stabilized blocks and see how they do in comparison.
As a side note, one thing I didn't anticipate is how the portion of the lime-stabilized blocks protruding above the waterline started to erode...while the portion of the blocks that were submerged stayed intact. My theory is that because temperatures dropped below freezing both nights, the un-submerged portion of the blocks experienced a freeze-thaw cycle that caused some deterioration. I'll confirm this in a follow-on experiment in which I use the same setup but keep the block above freezing.
