meteropolitan NYC to face with the flat earth without anyone doubt impact the world for the design of the building, in the form of design that the architect's table image to the world as kontruksi field to the end of the building high-rise tower to penetrate the height horizon. One of the areas of scholarly terggugah into the research effort to produce a building material more resistant to the manifold from the bomb explosion ulah terrorism.
"UHPFRC": Ultra High Performance Fiber Reinforced Concrete is one of the findings of the University of Liverpool research group leader Professor Steve Millard is diketengahkan to get the type of concrete material that will be more able to withstand impact power bomb explosion. A building with material of this new type of concrete is estimated to be more avoided collapse of the building immediately to the total collapse that is now as common on the many victims of global terrorism action bombardment. In the case which often result in victims under the rubble tertimbunnya-building debris caused many lost lives of the victim interconnect in such a small chance pass the opportunity to be saved from the gang auxiliary interconnect formation berujud the debris crushed ingot so.
Concrete UHPFRC have special characteristics in the dynamic buckling resilience: "dynamic bending capabilities" which means that the material will only be a little more / a small fraction in the orbit-gravel fraction seukuran --- the term "shrapnel" --- as the impact power bomb explosion in the high eksplosifitas concrete plate which are often solid, but at the same time getas.
In concrete engineering UHPFRC inserted adding extra thin layer braided "needle-thin steel fibers" instead of the usual effort to strengthen the steel sheet configuration tulangan concrete sole. Prof. Steve Millard berujar ensure that the research group has conducted a series of bomb explosion test test repeatedly to improve the strength of concrete in terms of rekayasanya dynamic buckling strength of concrete and increase the capacity to absorb energy explosive power ledak bomb.
Note results of experiments UHPFRC able to increase the strength of press and drag up to 500% stronger than the conventional concrete. While for the material characteristics of energy resources in meyerap bomb explosion impact absorption ability increased to: 1000-fold compared to standard concrete.
Prof. Millard more mengimbuhkan, now that many landmarks in the city center parawisata London that the order given concrete action in order to anticipate the dangers of terrorist bombs, but the extra concrete material is not made with the exact composition of the work in accordance to absorb the energy of explosion to avoid the occurrence of the fatal impact from a bomb explosion which hurl "shrapnel" that really be the end of the death of the victim in the total collapse of the building.
Until now, even though research Prof. Millard et al conducted in English but the implementation of the first time officially with the development is completed in the structure kontruksi roof of a building in Australia. Concrete plans in the next UHPFRC in the plan will be immediately applied to a number of building projects in the UK Government.
