Section 3.2 gives a brief on the types of SF commonly available. Section 3.3 deals with the physical characteristics that include particle size and size distribution (Section 3.3.1), specic gravity and bulk density (Section 3.3.2), and specic surface (Section 3.3.3). Chemical and mineralogical composition

are discussed in the Section 3.4. Aspects related to toxicity and occupational health are mentioned in Section 3.5. Section 3.6 summarizes quality control and the subsequent Section 3.7 discusses different aspects related to the addition of SF to cement and concrete. Finally Section 3.8 summarizes this chapter.
