The application of unshaped castables refractories undensified silica fume:
(1). Silica fume in Concrete
. Can increacing strength, density
. Frost resistance, Early strength,
. abrasion resistance performance
. anti-cavitations
(2). Silica fume in Cement
Strengthens the fibre cement product
(3) Silica fume is used in refractory
Greatly improved products strength and high temperature performance.
(4) Other Applications for Silica Fume
. Rubber industry
. Anti-caking industry
. Pellet binder
. Waterglass industry
