Building material of the future unveiled
Published: 27 October, 2009
SHEFFIELD: Scientists have developed a new building material that is fire-resistant to temperatures in excess of 1100°C. It is chiefly made from recycled material and is claimed to be as versatile as concrete.
Unlike concrete, 'liquid granite' does not explode at high temperatures. It can also withstand high temperatures for longer periods, offering valuable time in the event of a fire.
The material is made up of between 30% and 70% recycled material – mainly base products from industry.
It uses less than one-third of the cement used in precast concrete, and this also reduces its carbon footprint.
The product was developed at Sheffield Hallam University and is available from Liquid Granite Ltd. The material is being used by a number of organisations in building projects as it has a four-hour fire rating – the top level of protection in the case of a fire.
Professor Pal Mangat, director of the Centre of Infrastructure Management at Sheffield Hallam University developed the product.
"The product replaces most of the cement in standard concrete with a secret formula of products to change the basic properties of the material. I believe it has great potential for the future."
Bob Richards from Liquid Granite, said: "There has already been a great deal of interest from the building industry about this product, and it has been supplied for projects such as the Olympic Village and Stratford Shopping Centre in London in the form of fire-rated lintels manufactured by King Stone Products. It will really make a difference to the safety of our buildings and could potentially save lives."
