Barefoot Architect Benchmarking
• Elizabeth Primus• 2:1 ratio (sand to
cement)• Water (average slump)• Onion bag sheets• 3 Layers (cement-onion
bag)
Laying up• Results
– Dry weight: 66.5 lbs.– Dimensions: 31.25”x30.5”x1.25”
• 10” Diameter-waste hole– Max Load: ~350 lbs.
• Conclusions– 1.25” thickness gets us marginal
strength requirements (270 lbs.)– 96 lb./ft^3 (no course
aggregates)– Onion bag improves tensile
strength – Rice bag deconstruction could
create jobs
