|construction material/building materials;建築材料
"Constructional materials"（工程材料）指用于建築、基礎設施和工程結構中具有特定物理性能與機械特性的物質。這類材料需滿足承重、耐久、安全等核心要求，是現代工程技術的物質基礎。根據國際材料與結構研究實驗聯合會（RILEM）的定義，其分類涵蓋金屬、混凝土、木材、複合材料等七大類别。
在建築工程領域，鋼材和混凝土構成主要承重體系。美國混凝土協會（ACI）技術報告顯示，鋼筋混凝土的抗壓強度标準值需達到20-100MPa，其配比需遵循ASTM C150等國際規範。新型材料如碳纖維增強聚合物（CFRP）則通過美國國家标準技術研究院（NIST）認證，證實其抗拉強度可達傳統鋼材的5倍以上。
材料的環境適應性是當前研究重點。世界鋼鐵協會數據顯示，耐候鋼通過形成氧化保護層，可使橋梁使用壽命延長至120年。生态材料方面，美國環保署（EPA）認證的再生混凝土骨料，已實現建築廢棄物再利用率超70%。
Constructional Materials 指用于建築或結構中的材料，通常強調其在構造、裝配或承載方面的功能。以下是詳細解釋：
如需進一步了解具體材料類型或标準，可參考建築行業手冊或權威詞典釋義。
