The 28-day strengths range from 4.65 to 7.45 Mpa for the former, and 4.36–6.87 Mpa for the latter. The evolution of the strengths shows that at 0% the compressive strength hardly changes over time. The constancy of the mechanical strengths over time highlights the fact that after a period of 14–28 days, the optimum strength of the compressed earth bricks can be reached.
