Not your father's concrete

Article Abstract:

The concrete industry has started a new recycling procedure to convert the hazardous waste of organic polymers into reinforced concrete. Traditional concrete is a simple mixture of water, aggregate and cement with a few special types of additives for various effects. However, its entombing potential and its ability to incorporate other materials can be environmentally beneficial. The new procedure adopted by the concrete industry may help to reduce environmental pollution. The energy required for the production of concrete is much less as compared to that of the steel and plastic although the energy intensity required for the production of cement is very high.

Triumphant arches

Article Abstract:

The Natchez Trace Parkway bridge near Franklin, Tennessee, has been awarded the Outstanding Civil Engineering Award for 1995 for its aesthetic double arch design, which shows sensitivity to the historical perspective of the site. The bridge measures 1,572 ft long between abutment-bearing centerlines, with a main arch span of 582 ft. Figg Engineering Group, Tallahassee Fla., prepared the precast segmental design which has the same geometry and structural-element size as the design developed by the Federal Highway Administration to produce an identical finished product.

Is virtual reality for real?

Article Abstract:

Researchers at the Stanford University are studying the feasibility of using virtual reality to solve architectural and civil engineering problems. The researchers are optimistic that virtual reality will enable construction contractors to streamline building operations by developing high-tech animations of their master schedules. It will also help engineers and architects alike to resolve the conflict that normally arises during the preparation of the building design.
