Too many building structures, for which post-tensioning would provide a clearly superior solution, are conceived, designed and built as non -prestressed. For too long, non-prestressed and prestressed concrete have been treated as completely seperate entities and hence, prestressing is not yet regarded as a familiar and desirable construction option by many developers, architects, engineers and

Concrete has low volatile organic compound (VOC) emittance and does not degrade indoor air quality. Recyclable. Concrete structures in urban areas can be recycled into fill and road base material at the end of their useful life (about 5 to 20 percent of aggregate in precast concrete can be recycled concrete).
Safe Room Design: What is a Safe Room? Safe rooms are like fire extinguishers, you take them for granted and hope you never have to use them, but if you do, you’ll be glad you have them as they can save your life. Many people question how to build a safe room, especially in the Southeast United States, since it is so prone to various major weather events such as hurricanes and tropical
