ASTM C 618-05 Standard Specification for Coal Fly Ash and Raw or Calcined Natural Pozzolan for use in Concrete. Our powder is compliant with Class N.
ASTM C1438-99-05 Standard Specification for Latex and Powder Polymer Modifiers for Hydraulic Cement Concrete and Mortar For further information concerning theory, benefits, limitations, and applications of polymer-modified hydraulic cementitious mixtures, refer to ACI 548.3R-95 This specification covers performance criteria for latexes and re-dispersible powders (and re-dispersible powders which is our PNC™) when used as modifiers in hydraulic cement concretes and mortars to improve adhesion and reduce permeability, Special note: Prepackaged, proprietary mortar products are not included in this specification. Also, this specification covers only those materials contained in the reference or test mixtures listed in Test Methods C 1439. However, our development work has indicated that we can produce a finished product that meets or exceeds the ASTM requirements of C1438 from a performance standpoint.
