摘 要: | 研究了不同水灰比的混凝土由于自干燥和水分扩散引起的混凝土早期内部相对湿度(IRH)变化。试验结果表明,高水灰比混凝土的早期IRH变化主要受水分扩散的影响;而对于低水灰比的混凝土,其早期IRH变化不仅受水分扩散影响,同时也受到自干燥的影响。

Abstract: | Effect of different m(W)/m(C) on relative humidity ( IRH ) changes of concrete age resulting from moisture diffusion and internal at early self - desiccation is studied in here. The result from the study indicates that the IRH change of concrete at early age with high m ( W )/m ( C ) is mainly dependant on moisture diffusion and that with low m (W)/m (C) is mainly dependant on self - desiccation as well as moisture diffusion. |

Keywords: | concrete internal Relative Humidity self - desiccation moisture diffusion |
