Abstract (Summary)

Affordable housing is an ever-present need. Earthen construction techniques such as compressed earth block (CEB) technology are being used to mitigate affordable housing shortages. Existing literature on CEB technology has not been significantly contributed to by authors specializing in fields of geomechanics such as engineering geology, soil mechanics and rock engineering. This is a problem because CEB technology can be idealized as encompassing four phases of geomechanics, specifically as a natural soil deposit, an artificial loose soil mix, an artificial soft rock, and an artificial soft rock mass with systematic jointing. Combined with the lack of attention given by current building codes, CEB technology is in dire need of a methodological testing procedure intended to attest for the quality and integrity of the loose soils and consequent manufactured CEBs. A Standard of Care offers an acceptable format in which this objective could be accomplished. This thesis reviews current testing procedures applied to the idealized artificial loose soil mix and artificial soft rock phases of CEB technology. Additional testing procedures applicable to geomaterials are discussed particularly in their application to CEB technology. The research in this thesis explains how these testing procedures can be applied to professional practice and academic research involving CEB technology and also highlights deficiencies in current building codes and testing procedures. A proposed Standard of Care suggesting a methodical and significant testing procedure for CEB technology is included and fulfills the objective of the thesis.
