<div class="cita">Rammed earth is produced with low moisture and high compaction. When there is too much moisture in the mix, the earth will "jelly-up" rather than compact. The thinking has been that low moisture, high compaction makes a harder brick/block. Harder equals stronger, etc. What Minke is showing us is that the same soil with almost twice the ideal moisture content placed into a form and jigged (or in the earthbag fashion, tamped from above with a hand tamper), produces a finished block with a higher compression strengh than that of a ten percent moisture content rammed earth equivalent.

Los sacos con mezclas más húmedas rezuman al compactarlos, requieren menos golpes y los bloques resultan más gruesos. Hasta que se asientan son más blandos e inestables para sostenerse sobre ellos ( | Los sacos con mezclas más húmedas rezuman al compactarlos, requieren menos golpes y los bloques resultan más gruesos.
