APPLICATION OF ULTRA-HIGH-PERFORMANCE-FIBER REINFORCED CONCRETE TECHNOLOGY FOR PRESENT AND FUTURE
Ultra-high-performance fiber reinforced concrete (UHPFRC) is an advanced cementitious-based composite material that offers new opportunities for infrastructure works, building constructions, retrofitting methods and many niche markets.In the last two decades UHPFRC has been used for both structural and non-structural precast components in many countries.This outstanding technology has struggled to become a main-stream technology due to lack of design codes and high initial investment costs of manufacturing facilities.Moreover, the high cost of UHPFRC material makes it hard to compete with conventional designs optimized for other materials.Most projects in these countries have been motivated by government agencies as demonstration projects intended to encourage further implementation.However, for most of the countries, the follow-up implementation has been slow.Both private and governmental bodies are increasing their directives for the attention and initiative towards exploiting UHPFRC as a future concrete construction material, in the belief that UHPFRC technology embraces a more complete solution for sustainable construction with favorable life cycle values.This paper briefly presents the various examples on the application of UHPFRC technology especially in the context of Malaysia and Singapore.The examples given focus on those past successful and present projects and other potential applications of UHPFRC technology that are either in designed stage or yet to be discovered.One of the examples is an on-going project on five spans, total 192-metre-long, Kuala Terengganu By-Pass ST3 Bridge.Other examples are on 100-meter span box girder bridge, internet transmission tower;portal frame structure;cantilever retaining wall;anti-climb free standing wall;light-weight precast bathroom unit (PBU);external wall for precast-prefinished-volumetric-construction (PPVC).Finally, this paper tries to show how UHPFRC came into construction industry as an innovative solution for current engineering problems.
