Ar Fiberglass Roving

详情

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 **0 centigrade saturated Ca(HO)2solution for 4 hours remained strength >*2 Percent.diameter diminution <0.5 Percent.Soaked in **0 centigrade *0 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 = *4.5 Percent OR *6.2 Percent
