ASTM C928/C928M − 13 Standard Specification for Packaged Dry Rapid-Hardening Cementitious Materials for Concrete Repairs

ASTM C928/C928M − 13 Standard Specification for Packaged Dry Rapid-Hardening Cementitious Materials for Concrete Repairs

Scope
1.1 This specification covers packaged, dry, cementitious mortar or concrete materials for rapid repairs to hardened hydraulic-cement concrete pavements and structures. Materials that contain organic compounds, such as bitumens, epoxy resins, and polymers, as the principal binder are not included.

1.1.1 Packaged, dry, concrete material contains aggregate of which at least 5 % by mass of the total mixture is retained on a 9.5-mm [3⁄8-in.] sieve.

1.1.2 Packaged, dry, mortar material contains aggregate of which less than 5 % by mass of the total mixture is retained on a 9.5-mm [3⁄8-in.] sieve.

1.2 Aqueous solutions, aqueous emulsions or dispersions may be included as components of the packaged materials.

The manufacturer may specify that these liquids are to replace some or all of the mixing water.

1.3 Aggregates must be included as a component of the packaged materials.

The manufacturer may recommend job site addition of specific amounts and types of additional aggregates to his product for some uses.

However, such reformulated products are not within the scope of this specification.
