标准摘要
[中文适用范围]： 本文件规定了适用于纤维增强聚合物（FRP）网格作为混凝土中增强或预应力筋的测试方法，包括物理、机械、耐久性、长期耐久性和粘结性能。本文件中的FRP网格可用于修复现有钢筋混凝土（RC）结构和增强新建结构。本文件中的FRP网格由纤维和树脂基体组成。纤维类型包括芳纶纤维、玄武岩纤维、碳纤维或玻璃纤维。基体包括热固性树脂，如乙烯基酯、不饱和聚酯树脂，以及热塑性树脂，包括聚丙烯、聚酰胺和聚甲基丙烯酸甲酯。本文件中的FRP网格是相互连接的FRP棒的刚性阵列，不包括网状纤维织物和纺织品。在本文件中，耐久性指耐碱性。 [外文原描述]： This document specifies test methods applicable to fibre-reinforced polymer (FRP) grids as reinforcement or pre-stressing tendons in concrete, including physical, mechanical, durability, long term durability and bond properties. FRP grids in this document can be used for rehabilitating existing reinforced concrete (RC) structures and reinforcing new constructions. FRP grids in this document are made of fibre and resin matrix. The types of fibres are aramid fibre, basalt fibre, carbon fibre or glass fibre. The matrix includes thermosetting resins, such as vinylester, unsaturated polyester resins, as well as thermoplastic resins, including polypropylene, polyamides, and polymethyl methacrylate. FRP grids in this document are a rigid array of interconnected FRP bars, and do not include fibre textile and fabric with a mesh type. In this document, durability refers to alkali resistance.
