On several projects, designers have specified a very high modulus of
elasticity to stiffen a high-rise structure. Modulus of elasticity of
concrete is largely determined by the modulus of elasticity of the
aggregate. Adding silica fume increases the modulus by binding the
aggregate particles more tightly into the paste matrix.
