Chemical glass (C-glass) has a sodalime-borosilicate composition that is utilized in
corrosive environments where chemical stability is desired. It provides greater corrosion
resistance to acids than E-glass. Its primary use is in surface coatings of laminates used in
chemical and water pipes and tanks (Miller, 1987; Gurit Composite Technologies, 2008).
Specifically developed for use in concrete, alkali-resistant glass (AR-glass) is composed
of alkali-zirconium silicates. It is used in applications requiring greater chemical
resistance to alkaline chemicals (bases), such as in cement substrates and concrete.
Typical properties of E-, S-, C-, and AR-glass are presented in Table 2.1.
