Objective of the research:
Discover the effects of salt on local clay in the application of earth building (cob) by:
comparing results of strength and thermal insulation, between normal and less salt samples, also with effect of humidity.
Outcomes:
· Salt content of local clay: 1,066%.
· In comparison, the limit of total soluble salt allowed in the German Code DIN 18945 is 0.12%(Schroeder, 2012)
· Optimum Cob Mix Ratio: 3:1 (sand : clay)
· Sieve Analysis and Plasticity Test (Cob Mix) (see Figure 1 and 2)
