This section of the presentation describes using silica fume to enhance the
mechanical properties of concrete. The most significant improvements can be
seen in the compressive strength and modulus of elasticity. Initially,
designers took advantage of increases in strength and modulus in high-rise
structures. More recently, high-strength silica-fume concrete has been used
in substructures of high-performance concrete bridges. High-performance
concrete for bridges is discussed in a later section of the presentation.
