Quality controlling

Since load bearing and bracing rammed earth wall have in only very few cases been tested for planning laws and circumstances, hardly and norms and numbers exist, an affirmation of its use will be needed in every building situation. This requires locally identified testing circumstances before and after the building process. After the excavation, the local material will be analyzed; one or two mixture recipes will be made. With this mixture cylindrical probes are fabricated, burst strength, modulus of rupture and (if needed) creep resistance will be tested. On the basis of preliminary tests, monitoring tests will be conducted during the whole building process. Special attention has to be given to the dampness in the core of the rammed earth wall. The loading of the earthen walls with roofing constructions for example can only begin at the state of complete dryness within its core.
