Standard Specification for Silica Fume Used in Cementitious Mixtures
STANDARD published on 15.1.2020
Why Redline?
A PDF redline is a quick and easy way to compare all of the changes between the current, active standard and the previous version.
With a redline you'll immediately see:
Save Time and Trouble!
With a Redline you no longer have to spend time trying to determine what has changed in the new standard! Redlines save you time and ensure you see what the changes are to the standard.
Price
When you select the "Active + Redline" option you get both documents! Best of all, the cost of an Active + Redline is only slightly more than buying the Active Standard by itself.

This specification covers silica fume for use in concrete and other systems containing hydraulic cement. The material shall composed of silica fume, mostly of amorphous silica. Test methods for chemical analysis, moisture content and loss on ignition, bulk density, specific surface, air entrainment of mortar, strength acitivity index, reactivity with cement alkalis, and sulfate resistance of silica fume shall conform to this specification. Physical tests shall include determining the specimen´s density and the specific surface by utilizing the BET, nitrogen adsorption method. Silica fume shall be stored in such a manner as to permit easy access for the proper inspection and identification of each shipment.
