Of the18,000 miles of pre-stressed concrete cylinder pipe (PCCP) within the drinking water transmission infrastructure laid between 1945 and 1996 in the United States, almost one-half, or 8,600 miles of pipe, is considered to be end-of-life infrastructure, awaiting funding for replacement. The American Society of Civil Engineers (ASCE) gave the United States a grade of D for its drinking water inf ...

Conventional cement based construction materials such as stucco and concrete are prone to cracking with poor thermal insulation, and are very permeable to water. Repair of deteriorated cement based structures is a major problem, and in United States alone repair cost is estimated to be over $100 billion range. Commercial stuccos are susceptible to cracking under the influenced of repeated fluctu ...

During this Phase I research project, MER Corporation will investigate the effects of recycled polymers on cement-based materials, particularly the effects on mechanical properties, thermal conductivity, and stability to water and air. Conventional construction materials based on cement usually are poor thermal insulators and very permeable to water. The latter properties have been imp ...

Current methods of rubber/metal bonding lead to significant environmental concerns. The largest single commercial rubber-bonding application is the bonding of steel tire cords to sulfur-vulcanized natural rubber compounds. The current processes require that cobalt be added to the rubber to provide durable bonds. Cyanide also is used in the brass plating of steel tire cords. Tire separa ...
