New and original results and analyses of the interaction between Portland cement and silica fume related to compressive strength, split tensile strength, hydration

www.tylerley.com Thus, silica fume has a specific surface and an amorphous silica content, according to XRD, higher than that of quartz powder, which directly affects the chemical and physical reactivity of these Concrete containing silica fume can have very high strengths and good durability. Further, it is a very fine material having around 1/50 the size of ordinary Portland cement. The average size of a particle varies 0.1-0.3 microns and the minimum specific surface areas are around 15000m2/kg.
