AASHTO Designation: M 321-04 pdf free download

1.1.This specification covers high-reactivity pozzolans for use as a mineral admixture in portland cement concrete and mortar to fill small voids  and/or where pozzolanic action is desired.

High• reactivity pozzolans are microsilica products with a particle size typically one to two orders of magnitude smaller than portland cement.

These materials are usually supplied in undensified or densified dry form.

If the material is supplied  in a densified form, the tests should be performed on the as-collected undensified material  before being processed into densified form.

1.2.The values stated in SI units are to be regarded as the standard.

1.3.This standard does not purport to address all of the safetyconcerns,  if any, associated with its use.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations

prior to use. Read the material safety data sheets for materials used.

This  standard is not intended for specifying silica fume as defined in Section 3.3.

It is recommended that M 307 or ASTM C 1240 be used for that purpose.
