Abstract
In Limestone Association of Japan, in order to make everyone correctly understand the properties of crushed limestone aggregate, Committee on Concrete Aggregate was established by the specialists in limestone resources and concrete materials in 2008. In our Committee, we stacked the test data on the properties of concrete with limestone aggregate and widely collected latest technology findings and data. Furthermore, we made an in-depth study on various issues. Since we summarized the results as “Limestone Aggregate and Concrete - Addendum (2012) ”, we will introduce here its main points.石灰石鉱業協会ではコンクリート用石灰石骨材の特性を正しく理解していただくために,石灰石資源およびコンクリート材料の専門家によるコンクリート骨材研究会を2008年に設置した。同研究会では,石灰石骨材を使用したコンクリートの物性に関する試験データを積み重ねるとともに,最新の技術的所見・データを広く収集し,種々の検討を重ねた。今回,本成果を「石灰石骨材とコンクリート 補遺版2012」として取りまとめたので,その要点をここで紹介する。
Limestone Association of Japan,in order to make everyone correctly understand the properties of crushed limestone aggregate,Committee on Concrete Aggregate was established by the specialists in limestone resources andconcrete materials in 2008. in our Committee,we stacked the test data on the properties of concrete with limestone aggregate and widely collectedlatest technology findings and data. Furthermore,we made an in-depth study on various issues. Since we summarized the results as“Limestone Aggregate”and Concrete - Addendum(2012)”,we will introduce here its main points。石灰石矿业协会为了让人们正确理解混凝土用石灰石骨料的特性,于2008年成立了由石灰石资源及混凝土材料专家组成的混凝土骨料研究会。该研究会在积累有关使用石灰石骨料的混凝土物性的试验数据的同时,广泛收集最新的技术成果和数据,反复进行了各种研究。此次将本成果整理为《石灰石骨料与混凝土补缺版2012》,在此介绍要点。
