NOISE CONTROL LEADS TO BETTER BEARING DESIGNS

A British company in cooperation with two British research organizations has developed a glass-reinforced cement. The company, Pilkington, has negotiated licensing arrangements in many countries, including the U.S., to develop marketable products made of the material. It is being offered under the trade name, Cem-Fil. So far the material appears to have immediate applications in pipes, sandwich panels, marine hulls, and a variety of non-load bearing construction applications. At present load bearing applications are not being recommended but Pilkington expects them to be suitable with further development of the material. The glass-reinforced cement is similar to glass reinforced plastics except that cement replaces plastic as the matrix. The new technology enables production of thin section products. A key problem in developing the glass-reinforced cement was to overcome degradation of the fibers by alkaline attack in mixing and setting of the Portland cement. Cem-Fil, the developers say, is resistant to attack. The material can be pre-mixed with wet cement for subsequent pumping, casting, spinning, spraying, extruding, or injection molding. And a still-wet cement and glass fiber mixture can also be folded or pressed into thin flat sheets and profiles and into various complex shapes. According to Pilkington, the failure point of the glass-reinforced cement under loading compares more with ductile failure than with the brittle failure normally associated with cement and concrete products. The material is incombustible and is said to have high fire resistance and to be durable under a range of environmental conditions. /ARTICLE/
