White Silica Fume 10kg

Silica Fume is used in high performance concrete as a Pozzolan to improve its properties. A Pozzolan is a material that when in the presence of water has a chemical reaction and forms compounds that possess cementitious properties. Silica Fume is an ultrafine material that is approximately 100 times smaller than the average cement particle.

Silica Fume, White, 50lb bag - Fishstone - Concrete

Silica fume consists primarily of amorphous (non-crystalline) silicon dioxide (SiO2). Its individual particles are extremely small, approximately 1/100th the size of an average cement particle. It therefore effectively fills in empty pores in the cement and helps produce a stronger, more compact material.
