Abstract:
To limit lateral deformations and ensure occupant comfort, designers of tall concrete buildings may specify a high modulus of elasticity (MOE) for the structural concrete. While MOE can be raised by increasing concrete compressive strength or using stiffer aggregates, such mixtures can be prone to brittle behavior and high autogenous shrinkage. There is an alternative way to obtain a high MOE, using carbon nanotubes, which, if well dispersed, can increase MOE of concrete without increasing the compressive strength.
