From a rioja to a hard place: university researchers in Sheffield have hit on the idea of using bottles to make concrete

Article Abstract:

University researchers in Sheffield have developed a new type of concrete, made using waste glass. The resulting marble-like material has been christened Metzzo, and is expected to be in mass production by the end of 1996. It could be used for architraves, furniture, floor tiles, and external cladding. It is a mix of waste glass, Portland cement, silicates, pigments and cement formed into moulds. In the early stages of the project, purity was the key to durability, as impurities in the glass weakened the mix. The concrete was also made stronger with the user of small pieces of waste glass.

The roaring twenties

Article Abstract:

The wages of UK quantity surveyor graduates increased by an average of 8.1% during 1998, with an average salary at 12,000 pound sterling per year. Experienced chartered building surveyors wages increased an average of 7.4% during 1998, with an average salary of 20,300 pounds sterling per year. A lack of engineers has forced many firms to take on graduates at higher rates of pay if they can demonstrate all round engineering skills. A graduate engineer can expect to earn about 13,600 pound sterling per year in London and Southern areas.

Patent place: a new method of strengthening structural concrete against earthquakes an in invisible roof ventilation system are among the patents recently granted or still pending

Article Abstract:

Researchers at the University of Sheffield have developed a new way of strengthening structural concrete against earthquakes by wrapping strips of high strength steel around structural elements, which prevents lateral expansion. Strips of high tensile material can be easily applied and less material is required to secure the structural element.
