...In this case, the SiO2 that constitutes the skeletal structure of the glass dissolves. In recent years, a composite material called GRC (short for glass fiber reinforced cement) has been developed that uses glass fibers to reinforce cement, but because cement is highly alkaline, ordinary SiO2 -based glass cannot be used at all, so a special alkali-resistant glass fiber containing 10 to 20% ZrO2 is used. *Some of the terminology that refers to "glass fiber reinforced cement" is listed below.

…この場合には,ガラスの骨格構造を構成しているSiO2が溶け出してくる。近年セメントの補強用にガラス繊維を使用した複合材料であるGRC(glass fiber reinforced cementの略)があるが,セメントは強アルカリ性のため通常のSiO2系ガラスではまったく使用できず,ZrO2を10~20%含有する特殊な耐アルカリ性ガラス繊維が用いられている。 ※「glass fiber reinforced cement」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
