摘要: Abstract Better understanding of water transport in concrete is great significance to assess the durability and predict service life. In this study, effects cement ratio (W/C), volume fraction coarse aggregate (Va) particle size on absorption were investigated. Besides, more attention was paid effect saturation degree (θ) concrete. The results showed that process can be divided into two stages: rapid steady absorption. rate increases with increasing W/C An increase Va reduces concrete; however, has no unsaturated initial decreases increasing. According experiment results, a model for predicting any established. From that, calculated.
