The subject of the present invention is to provide a prestressed concrete that jointly uses chemical stress induced by an expansive material and mechanical stress induced by a rust-resistant wire, achieves weight reduction and crack resistance, and can be used for non-primary structural members such as general building members. The prestressed concrete for non-primary structural members, is characterized by the introduction of mechanical stress induced by a tendon and chemical stress induced by an expansive material for concrete, wherein the tendon is a rust-resistant continuous fiber reinforcing wire. 本发明的课题在于提供种预应力混凝土，其可用于般建筑构件等的非主要结构构件，其并用膨胀材料产生的化学应力与抗锈线材产生的机械应力，实现轻量化与龟裂抑制。本发明解决课题的手段为种非主要结构构件用预应力混凝土，其特征为，导入了张紧材料产生的机械应力与混凝土用膨胀材料产生的化学应力，且该张紧材料为抗锈性的连续纤维加强线材。
