Porosity and Calcium Hydroxide in Concretes with Silica Fume
For the systems containing silica fume, the results are quite different as the area occupied by large pores actually increases with increasing age for both sets of the interfacial zone images and for the bulk paste images for the system containing 20% silica fume.
BRITEFUME – Technical Co.
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.
