"It is the purpose of this research to investigate the creep in a thin concrete slab under a long-time prestress load with the compressive load being applied to the edge of the slab through a bearing plate of small dimensions.
Seven plain concrete slabs, 3' x 4' x 4", approximately one year old, made of normal cement and approved aggregate were subjected to the following loading conditions: (1) Three slabs loaded at the center of the greater dimension with a prestress load or 20,000 pounds applied over an area of eight square inches, (2) Three slabs loaded symmetrically at six …
