摘要: Mercury intrusion porosimetry is a widely used technique to determine the pore size distribution in porous materials. However, this does not provide information about shapes and locations of pores. A new developed, which gallium (Ga) as an alternative liquid because its property being solid at normal room temperature (melting point: 29.8 °C). This permits examination pores using image analysis. The applied hardened cement paste. Ga observed through electron probe microanalyzer (EPMA), paste are discussed.
