ASTM C1697
Full Name
ASTM C1697 – Standard Specification for Blended Supplementary Cementitious Materials
Scope
ASTM C1697 covers blended supplementary cementitious materials (BSCM) that result from the blending or intergrinding of two or three ASTM compliant supplementary cementitious materials, for use in concrete or mortar where hydraulic or pozzolanic action, or both, is desired.
The supplementary cementitious materials include slag cement conforming to Specification C989, natural pozzolans and coal fly ash conforming to Specification C618 and silica fume conforming to Specification C1240.
ASTM C1697 covers various aspects of BSCM, including:
- Chemical composition: specifies the acceptable ranges for major and minor oxides present in the material.
- Physical properties: addresses requirements related to fineness, loss on ignition, and other relevant characteristics.
- Performance criteria: establishes performance standards for BSCM, such as reactivity and compatibility with other concrete constituents.
Supplementary cementitious materials offer several benefits, including improved concrete strength, durability, and workability. Additionally, they can contribute to reduced environmental impact by decreasing the amount of Portland cement required.
