Bid to reduce blasts impact.ENGINEERS at the University of Liverpool The University of Liverpool is a university in the city of Liverpool, England. History The University was established in 1881 as University College Liverpool, admitting its first students in 1882. have tested a new form of concrete designed to reduce the impact of bomb blasts. The fibre-reinforced concrete was found to absorb a thousand times more energy than plain concrete and could therefore be used for bomb-proof litter bins and protection barriers. Although not yet used in the UK, the concrete has been utilised in Australia in the design of slender Slender “though well-landed, an idiot.” [Br. Lit.: Merry Wives of Windsor] See : Stupidity footbridges and in the roofs of government buildings to strengthen them against mortar attack. Professor Steve Millard said: "Many London tourist landmarks are surrounded by concrete to protect against terrorist attacks. However, the material does not absorb sufficient energy to prevent the creation of shrapnel shrapnel Originally, a type of projectile invented by the British artillery officer Henry Shrapnel (1761–1842), containing small spherical bullets and an explosive charge to scatter the shot and fragments of the shell casing. . UHPFRC is different because needle-thin steel fibres are added into the concrete mix. "We carried out a number of high explosion tests. Our results showed the new UHPFRC material had an enhanced tension and compression strength 500% greater than conventional concrete." |
