JIS A 6207:2016 PDF Download

JIS A 6207:2016 standard provides specifications for the use of silica fume as an admixture in concrete and mortar. Silica fume refers to a material that comes in powdery, granular, or slurry forms. This standard aims to establish guidelines for the quality and characteristics of silica fume when used in concrete applications.

The standard ensures that the silica fume used for concrete and mortar production meets specific requirements. These requirements include physical properties, such as particle size distribution, specific surface area, and moisture content, as well as chemical properties, such as silica content, loss on ignition, and impurities. By adhering to these specifications, the standard helps ensure consistent and reliable performance of concrete and mortar mixtures incorporating silica fume.

The use of silica fume as an admixture in concrete offers several benefits, including improved durability, reduced permeability, enhanced strength, and increased resistance to chemical attack. This standard sets out the necessary criteria for silica fume to achieve these desired properties, ensuring that it meets the intended purpose and enhances the performance of the concrete or mortar in which it is used.
