- Abstract
- For the program on the investigation of low-cost house constructions, specimens representing adobe, bitudobe, monolithic terracrete, terracrete-block, and rammed-earth walls were constructed with the cooperation of The Office of Indian Affairs and the National Youth Administration. These specimens were subjected to structural, heat-transfer, and water-permeability tests. Sixty structural specimens were supbejected to compressive, transverse, concentrated, and impact loads. The transverse, concentrated, and impact loads were applied to one face. The loads simulated those to which elements of a house are subjected in actual service. The deformation under load and the sets after the load was removed were measured for each increment of load. Five heat-transfer specimens were subjected to a temperature differential that might occur in actual service. Five water-permeability specimens were tested under conditions that simulated exposure to a heavy, wind-driven rain.
