Abstract

The dynamics and Durability of Permanent Form Mortar were observed. The results were as the followings. To construct New permanent form, this study constructed permanent form with fiber mortar. In this course glass fiber and polymer, fine aggregate were substituted with river sand and crush sand. To understand material quality effect, flexible mortar and inflexible mortar were tested. According to the microstructure of polymermatrix test by SEM, higher density by Co-matrix effect from polymer addiction was observed. This is considered to increase acid-resistanc, impact proof strenght. In the test of durability of freezing and thawing, polymer mortar was proved to be water proof. It seems to be improved in its characteristics in proportion to increasing W/C ratio. When the W/C ratio is 30%, it is most effective.
