Application Summary AI generated
This standard specifies the technical requirements, test methods, and quality specifications for natural and artificial pozzolanic materials used as active mineral admixtures in cement production. It is applied by cement manufacturers and construction material testing laboratories in China to ensure that pozzolanic materials like volcanic ash, tuff, or fly ash meet the necessary chemical and physical properties for blending with Portland cement clinker. The standard governs the material's fineness, loss on ignition, and pozzolanic activity index to guarantee consistent performance in concrete and mortar applications.
