Influence of Fine Aggregate Properties on Judgment of Saturated Surface Dry Conditions

細骨材の表乾状態判定に対する試料特性の影響

In recent years, aggregates have become increasingly varied, with a corresponding expansion of their range of properties, making the application of existing measurement methods increasingly difficult. Aggregate properties, including the density and water absorption rate of fine aggregate, are of great importance for concrete mix design. The Committee on Concreting Technologies established the Fine Aggregate Quality Working Group for the purpose of organizing density and water absorption coefficient measurement methods for fine aggregate, and based on their measurement principles, to investigate the properties of fine aggregate that make the application of these measurement methods difficult. This report summarizes the test results obtained as part of these activities and presents the differences in the results obtained from density and water absorption coefficient measurements of fine aggregates with a wide range of properties performed with methods that are based on differing measurement principles.近年，骨材が多様化しており，物性の範囲も広くなっている。このため，既往の測定試験法ではその適用が困難となる場合がある。コンクリートの配（調）合設計上重要な意味を持つ，細骨材の密度および吸水率試験もその1つである。コンクリート基本技術調査委員会では，細骨材品質WGを設置し，細骨材に対する密度および吸水率試験法の整理を行い，それらの測定原理に基づいて，各種の細骨材にこれらの試験方法の適用が困難となる細骨材物性を検討してきた。本報告は，この活動の一環として実施した実験結果をまとめ，広範囲の物性を有する細骨材の密度および吸水率を，異なる測定原理の試験方法で測定した場合の結果の変動について検討したものである。
