Characteristics of ultra-high performance ‘ductile’ concrete and its impact on sustainable construction

Abstract

This article presents an overview of the material characteristics of a Malaysia blend of ultra-high performance 'ductile' concrete (UHPdC). Examples of the environmental impact calculations of UHPdC structures compared to that of conventional reinforced concrete (RC) design are presented. The comparison studies show that many structures constructed from UHPdC are generally more environmentally sustainable than built of the conventional RC with respect to the reduction of CO2 emissions, embodied energy and global warming potential. The enhanced durability of UHPdC also provides for significant improvements in the design life, further supporting the concept of sustainable development.
