摘要：
We determined the free + adsorbed water and the bound water in aggregates and cement pastes using conventional gravimetric analysis and prompt γ-ray analysis, respectively, to evaluate the total water content in concretes. The contents of free + adsorbed water and bound water in some geochemical references were also determined to confirm the accuracy in the present work. The content of each water in aggregates collected from different quarries and cement pastes with different water-to-cement ratios were analyzed. The total water content in young concrete was evaluated on the basis of the analytical values.
