Abstract:Preventing early bond by using greased or oiled round steel rods and slowly stressing these rods against the body of the concrete, the writer built some 1400 posts and several hundred building slabs. With steel in tension and concrete in compression, neither posts nor slabs cracked and showed no weathering. A laboratory test shows how a beam so built acts when loaded to failure and the curves show how high strength steel may be used to save steel or to produce higher strength beams without increasing size or weight.
