CARBON NANOTUBE COMPOSITE PRETENSIONED SPUN HIGH STRENGTH CONCRETE PILE AND CONSTRUCTION METHODS THEREOF

摘要

The present invention provides a carbon nanotube (CNT) composite pretensioned spun high strength concrete (PHC) pile and a construction method thereof. The CNT composite PHC pile comprises: a first composite PHC upper pile forming an upper portion thereof and containing a concrete pile including a CNT; and a second PHC lower pile forming a lower portion thereof. The CNT composite PHC pile aqueously disperses the CNT in centrifugally formed concrete to improve structural performance such as bending performance and shear performance. The CNT composite PHC pile can be used to provide economic efficiency and safety with respect to influence of horizontal force and bending moment such as an excessive eccentric soil pressure and an unpredicted earthquake load.
