Research Abstract |
This research was conducted during the three year period from 1994 to 1996. We made this inquiry becase tile makers are having a hard time producing tiles of high-level craftsmanship that do not fall off from outdoor walls. We experimentally examined the dynamic behavior of tiling with highly elastic adhesives, superior workability and good pliability. Although the adhesive strength of highly elastic adhesives is weak compared to mortar, we found that it is strong enough. And it was also made clear that because of the good pliability, the highly elastic adhesives efficiently prevented tile peel-off in use with ferroconcrete structures. Also, according to another organization, as a coating material, there is violet burning when the surface tiles or the joints fall off, and there is the gas problem. But compared to mortar, there is no big difference in performance. As for the last fiscal year, from the results and experience up to now, as we reexamined the method of evaluating the mutual

behavior of the adhesive and the back of the tile (repetition-fatigue experiment) in mm units, we examined the development of the shortening of time taken for the experiments (impact tests), the method of simple experiments we were able to do at the place (twisting experiment), etc. As for the results, although the problem of deformation remained in the tests for fatigue, we have arranged the evaluations of the durability and adhesive strength. We dscovered that we could evaluate the small areas that the adhesive does not stick, etc., and that we could shorten the experimenting time very much with impact tests, and without using heavy equipment, we learned that the experimenting methodology of high precision impact tests was applicable. It is necessary to use this method in the future, obtain a lot of data, elevate the degree of precision and evaluation, and compare it to the conventional methods. Furthermore, the two year outdoor exposure experiments are still in progress. Follow-up experiments for this still remain to be done for next time. Less
