A Hwang-toh, one sort of great nature, is fit with constructure friendly, in this situation that occuring harmful objects of cement. Although, in this case that not to practical use because of cracking by shrinkage and low strength, the study is started from that supplying PVA fiber(a organic fiber) in Hwang-toh by replacement ratio. In order to improve tensile strength, bending strength and tenacity of Hwang-toh as a structure and obtain relatively bigger adhesion strength of it. The result of study, However, the application ability is not much enough. Only one result that checked out is that replacing PVA 0.3% followed Hwang-toh replacement ratio in 25% of Hwang-toh has appliment ability as a structure. Keep studying with result is able to use valuable Hwang-toh, as constructure material for practical use. |
