Abstract
A method of fabricating an earthen construction formation and of testing the earthen construction formation are presented. The earthen construction formation is prepared by way of a site-derived earthen material mixture. The site-derived earthen material mixture can be free of cement stabilizer additives. A geotextile fabric formwork is filled with the site-derived earthen material mixture. The geotextile fabric formwork is flexible and permeable in nature. The site-derived earthen material mixture is allowed to dry in the geotextile fabric formwork.
Claims20
A method of fabricating an earthen construction formation, the method comprising:
- preparing a site-derived earthen material mixture, wherein the site-derived earthen material mixture lacks cement stabilizer additives, the site-derived earthen material mixture constituting a pourable site-derived unstabilized earthen material mixture;
- filling a geotextile fabric formwork with the pourable site-derived unstabilized earthen material mixture, the geotextile fabric formwork exhibiting flexibility and permeability;
- maintaining the geotextile fabric formwork with the pourable site-derived unstabilized earthen material mixture in an upright position;
- and
- allowing the pourable site-derived unstabilized earthen material mixture filled in the geotextile fabric formwork to dry while maintained in the upright position.
A method of fabricating an earthen construction formation, the method comprising:
- preparing a site-derived earthen material mixture, the site-derived earthen material mixture constituting a pourable site-derived earthen material mixture;
- filling a geotextile fabric formwork with the pourable site-derived earthen material mixture;
- maintaining the geotextile fabric formwork with the pourable site-derived earthen material mixture in an upright position and on a local ground;
- and
- allowing the pourable site-derived earthen material mixture filled in the geotextile fabric formwork to dry while maintained in the upright position and while on the local ground.
A method of testing an earthen construction formation prepared via a site-derived earthen material mixture, the method comprising:
- placing a geotextile fabric formwork in a testing support structure, the geotextile fabric formwork exhibiting flexibility and permeability, the testing support structure supporting the geotextile fabric formwork above a local ground and having a plurality of openings at least at a bottom thereof;
- filling the geotextile fabric formwork with the site-derived earthen material mixture while the geotextile fabric formwork is placed in the testing support structure, and allowing the site-derived earthen material mixture filled in the geotextile fabric formwork to dry while the geotextile fabric formwork is placed in the testing support structure;
- and
- performing testing to the earthen construction formation.
