Yield stress measurement for earth-based building materials: the weighted plunger test

Earth-based building material processing is a challenge for new constructions. Moreover, field measurements to obtain the rheological properties of fresh materials are required in applications. However, existing field-oriented tests were designed more flowable materials, and protocols stiff rarely available. In this paper, test yield stress developed earth-based accurate enough identify small variations demanding The squeeze used as reference measurement stress. For pure clays two clay-based stresses could not be easily linked tests: Atterberg limits falling plunger. Finally, weighted plunger was measure accurately test. development earthen will help implement techniques on field.
