PDX-Silica fume: Supplementary Cementitious Materials (SCMs)

Description

A very fine and very reactive pozzolanic material produced from the manufacture of elemental silicon or ferrosilicon alloys. Silica fume reacts chemically with the free lime in the cement paste to form calcium silicate hydrate (CSH) gel. This reaction is called a pozzolanic reaction where the CSH gel acts as a binder to hold the constituents together and fills the air void structures in the concrete.
