초록
영어
The purposes of this study is investigating the variation of Find Pore Structure and the mechanical properties in heated temperature Using Nitrogen Adsorption method. As results of this study comprehended the characteristic of porosity of High-heated Concrete, the following can be summarized; Generally Pore Distribution Variation showed a tendency to increased affected by the influence of high water-cement ratios(W/C). On the whole porosity showed a
tendency to decreased according as High-heated temperature irrespective of water-cement ratios(W/C). The compressive strength and the modulus of elasticity were degraded depending on a rise of heated temperature.
