Newreach Silica Fume 950. Silica Fume NR950 is a dry powder available in two forms,densified silica fume and undensified silica fume . Silica Fume NR950 is a pozzolanic material that consists primarily of fine silicon dioxide particles in a non-crystalline form.
What is Silica Fume?
Silica fume consists primarily of amorphous (non-crystalline) silicon dioxide (SiO2). The individual particles are extremely small, approximately 1/100th the size of an average cement particle. Because of its fine particles, large surface area, and the high SiO2 content, silica fume is a very reactive pozzolan when used in concrete.
