DEVELOPMENT OF AN ENVIRONMENTALLY-FRIENDLY GROUND GRANULATED BLAST-FURNACE SLAG BLENDED CEMENT WITH A LIMESTONE POWDER

石灰石微粉末を利用した環境負荷の低い混合セメントの開発

An environment-friendly cement was developed to control greenhouse gas (carbon dioxide) emissions by replacing some of the ground granulated blast-furnace slag blended cement with limestone powder (content of ground granulated blast-furnace slag is fixed to 44 percent). Reducing the water-to-binder ratio was necessary for cement containing 15 to 25 percent limestone powder to obtain a 28-day compressive strength equivalent to that of type B ground granulated blast-furnace slag blended cement. However, the concrete was found to be less base cement was necessary than for type B ground granulated blast-furnace slag blended cement, reducing carbon dioxide emissions from the cement by 14％. And durability of the concrete was found to be equal to that of concrete using type B ground granulated blast-furnace slag blended cement.温室効果ガスとしての二酸化炭素の排出量削減を目的に、高炉セメントの一部を石灰石微粉末で置換した混合セメントを開発した。材齢28日における圧縮強度を同一としたコンクリートで比較した結果、石灰石微粉末で置換した混合セメントは単位結合材量が増加するものの、クリンカー量を低減でき、その結果、セメントに起因する二酸化炭素排出量を高炉セメントB種に比べて最大で14％削減できた。また、コンクリートの各種耐久性能は高炉セメントB種と同等であり、高い実用性を有した。
