Abstract

On March 21, 2013, JIS A 5011-1 (Slag aggregate for concrete Part 1 : Blast furnace slag aggregate) was revised. In this first revision since 2003, aggregate quality standards were revised and new chemical composition analysis methods were added. Based on “Guidance for introducing environmental aspects in construction sector standards” Annex I: “Guidance for introducing environmentally sound quality of chemicals and inspection method to slag aggregate for concrete” established by the Technical Committee on Civil Engineering and the Technical Committee on Architecture under the Japanese Industrial Standards Committee's Standards Board in July 2011, environmental safety and quality standards and inspection methods were established. This article describes the main points of these revisions.2013年3月21日に,JIS A 5011-1(コンクリート用スラグ骨材-第1部:高炉スラグ骨材)が改正された。前回2003年以来の改正であり,骨材の品質項目の見直しおよび化学成分分析方法の追加に加えて2011年7月に日本工業標準調査会標準部会の土木技術専門委員会および建築技術専門委員会が共同で定めた“建設分野の規格への環境側面の導入に関する指針 附属書Ⅰ コンクリート用スラグ骨材に環境安全品質及びその検査方法を導入するための指針”に基づき,環境安全品質に関わる基準および検査方法を規定した。これらの改正の要点について紹介する。

JIS A 5011-1(混凝土用灰渣骨料-第1部分:高炉灰渣骨料)修改要点
On March 21, 2013, JIS a5011 -1 (Slag aggregate for concrete Part 1:Blast furnace slag aggregate) was revised. In this first revision since 2003,aggregate quality standards were revised and new chemical composition analysis methods were added.Based on“Guidance for introducing environmental aspects in construction sector standards”Annex I:“Guidance for introducing environmentally sound quality of chemicals and inspection method to slagaggregate for concrete’established by the Technical Committee on Civil Engineering and theTechnical Committee on Architecture under the Japanese工业标准Committee's标准Board in July 2011,environmental safety and quality standards and inspection methods were established. This articledescribes the main points of these revisions.2013年3月21日,JIS A 5011-1(混凝土用灰渣骨料-1部:高炉炉渣骨料)被修改了。这是自2003年以来的第一次修订,除了重新评估骨料的品质项目以及追加化学成分分析方法之外,2011年7月日本工业标准调查会标准部会的土木技术专门委员会以及建筑技术专门委员会共同制定了“关于在建设领域规格中引入环境方面的规定”。指针附属书i用矿渣混凝土骨料环境安全质量及检查方法为方针”的基础上,引入环境安全质量相关标准及检测方法进行了规定。介绍这些修改的要点。
