TESTS OF SPONGE RUBBER JOINT-FILLER MATERIALS,
Abstract
The present design requires that filler materials proposed for use in joints between elevator tower walls and other portions of the structure at Yellowtail Dam must be capable of a high degree of deformation at relatively low loads and repeated high percent recovery to insure permanent closure of these joints. Two approximately 1-foot square samples of sponge rubber concrete jointfiller, Laboratory Samples No. M-4727 and M-4728 were secured and tested to determine their applicability to this type of construction. In particular it was desired to determine the stress deformation curve from zero stress-zero deformation, to a deformation of 50 percent of the original thickness and to then measure the rate of recovery upon load release. This was to be repeated for a second loading on each sample, after which loading was to be repeated utilizing a loading to compress the sample to 25 percent of its original thickness, 75 percent deformation.
