中文摘要 | 本研究利用氣體滲透法原理,探討被覆材料在高溫作用下孔隙結構之變化,並瞭 解高溫延時試驗及耐火試驗間孔隙之關係。研究發現,孔隙隨溫度升高有增大的趨勢,而孔 隙率與溫度變化成正相關。養護完成後試體之含水率,在高溫作用下,對於孔隙結構之變化 並無顯著之影響。 |
英文摘要 | The research probed the variation of porosity of sprayed fire-resistive materials (SFRM) at high temperatures, and studied the porosity relationship between the exposed duration of high temperature test and fire resisting test, by using gas permeability principle and capillary flow porometer test. The results show that the pore size greater as the increase of temperature. The porosity and temperature have relationship of direct proportion. Between the moisture content of the specimen and the pore structure had no apparent effects at high temperatures. |
