Outline of Final Research Achievements

I developed a method to measure the pore structure of concrete. There are many pores in concrete, and their compressive strength and transport properties differ depending on pore size distribution. Therefore, it is very important to clarify the pore size distribution in concrete. Pore size distribution is clarified by the thermoporometry method of measuring the amount of pore from the heat quantity generated during freezing and thawing of the water present inside the pore, and the proton NMR measurement focusing on the mobility of hydrogen. It became clear by this method that the distribution of the water present in the pore is greatly different between blended cement paste and ordinary cement paste.

Academic Significance and Societal Importance of the Research Achievements

コンクリートの空隙構造を測定するための手法の開発を行った。コンクリートには多くの空隙が存在しその分布によって圧縮強度や物質透過性能が異なる。したがってコンクリート中の空隙の分布を明らかにすることが非常に重要である。その手法として空隙内部に存在する水の凍結融解時に発生する熱量からその量を測定するサーモポロメトリー法と水素の運動性に着目したプロトンNMR測定によってそれらを明らかにした。このことからコンクリート構造物の耐久性を評価する手法を開発した。
