|construction material/building materials;建筑材料
"Constructional materials"（工程材料）指用于建筑、基础设施和工程结构中具有特定物理性能与机械特性的物质。这类材料需满足承重、耐久、安全等核心要求，是现代工程技术的物质基础。根据国际材料与结构研究实验联合会（RILEM）的定义，其分类涵盖金属、混凝土、木材、复合材料等七大类别。
在建筑工程领域，钢材和混凝土构成主要承重体系。美国混凝土协会（ACI）技术报告显示，钢筋混凝土的抗压强度标准值需达到20-100MPa，其配比需遵循ASTM C150等国际规范。新型材料如碳纤维增强聚合物（CFRP）则通过美国国家标准技术研究院（NIST）认证，证实其抗拉强度可达传统钢材的5倍以上。
材料的环境适应性是当前研究重点。世界钢铁协会数据显示，耐候钢通过形成氧化保护层，可使桥梁使用寿命延长至120年。生态材料方面，美国环保署（EPA）认证的再生混凝土骨料，已实现建筑废弃物再利用率超70%。
Constructional Materials 指用于建筑或结构中的材料，通常强调其在构造、装配或承载方面的功能。以下是详细解释：
如需进一步了解具体材料类型或标准，可参考建筑行业手册或权威词典释义。
