摘要: |
用石墨水泥砂浆注浆钢纤维混凝土(graphite-cement slurry infiltrated fiber concrete,GSIF-CON)试件进行了不同环境温度条件下的升温和化冰试验.结果表明:GSIFCON材料具有良好的电热升温性能,若试件底部和侧部设有3 cm厚的保温层,其升温速率可提高40%以上;在相同的负温环境下,电功率对化冰热效率和热量损失影响较小,但对化冰时间影响显著;在相同的负温环境和电功率条件下,化冰热效率随冰层厚度的增加而明显提高. |

Abstract: |
Graphite-cement slurry infiltrated fiber concrete(GSIFCON) specimens were used in the temperature rising and deicing tests under different environmental temperature.The test results indicate that GSIFCON has good electrothermal properties.If a 3 cm thickness insulating layer is placed at the side and in the bottom of the specimens,the temperature rising speed of the specimens increases by over 40%.Under different negative temperature environment,the power has a little influence on the deicing efficiency and... |
