PROBLEM TO BE SOLVED: To provide a sizing agent that improves the convergence of glass strands used in a cement composite material and is excellent in affinity with mortar and impregnation property.SOLUTION: Provided is a sizing agent for forming film on the surface of a glass fiber for cement composite material, and containing a water-containing solvent and a solid component to be a film, and when the concentration is adjusted so that the concentration of the solid component is 10 mass%, the pH shows 3.5 to 5.5. Also, the sizing agent contains polyvinyl acetate, polyurethane, and an amine compound.SELECTED DRAWING: None 【課題】セメント複合材に使用するガラスストランドの集束性を向上させ、かつモルタルとの親和性及び含浸性に優れたサイジング剤を提供する。【解決手段】セメント複合材用のガラス繊維の表面被膜形成用のサイジング剤であって、水を含む溶媒と、被膜となる固形成分とを含み、固形成分の濃度が１０質量％となるように濃度調整したときに、ｐＨが３．５〜５．５を示す。また、サイジング剤は、ポリ酢酸ビニルと、ポリウレタンと、アミン化合物とを含有する。【選択図】なし
