Alkali resistant fiberglass (AR fiberglass ) is a fiberglass that can be corrosive resistant to alkaline substance, such as cement. It can be used in glassfiber-reinforced cement (GRC), gypsum and other organic and inorganic material. It is also ideal replacement of steel and asbestos in unloaded cement component part. GRC has a light, high strength, incombustible, designable and easily shaped, as a new inorganic composite, it has been widely used in the fields of building, civil construction, agriculture and fishing industry, environment decoration, chemical industry and military project.Soaked in 100 centigrade saturated Ca(HO)2solution for 4 hours remained strength >82 Percent.diameter diminution < 0.5 Percent.Soaked in 100 centigrade 10 Percent NaHO solution for 1 hours, weight loss < 5 Percent(without size ).Its alkaline resistance through the " SIC" test of Berlin University in Germany, meanwhile meet the requirements of PCI (prestressed concrete institution) and international GRC institution.zro2 = 14.5 Percent OR 16.2 Percent
