摘要
PROBLEM TO BE SOLVED: To provide a composition for glass fiber having high elasticity modulus, good in productivity and further capable of easily manufacturing a glass fiber with fine count.SOLUTION: There is provided a composition for glass fiber containing, by mass% in terms of oxide, SiO:50 to 70%, AlO:15 to 25%, MgO:3 to 13%, CaO:3 to 15%, BO:0.5 to 5% as a glass composition, and having temperature difference ΔTxy between molding temperature Tx and liquid phase temperature Ty of 90°C or more, molding temperature Tx of 1365°C or less, elastic modulus E of 90 GPa or more, and linear thermal expansion coefficient α of 45×10or less. There is provided a composition for glass fiber having a shape of a product of chopped strand, yarn or roving and compounded with concrete or mortar.SELECTED DRAWING: None
