Precast concrete manufacturing has an intrinsic environmental advantage compared with constructing similar products at a job site. Although it may be something we take for granted, this advantage has always been an important component of any precast product, and in today's environmentally conscious world it is becoming a more important value ...

Ivan / Getty Images. Another common concrete problem is scaling. Scaling occurs when the concrete surface breaks off and keeps peeling away. Scaling could also occur if non-air entrained concrete is exposed to freeze-thaw cycles, inadequate concrete strength, or inadequate curing procedure.. How can concrete scaling be avoided:

The concrete structural-frame construction has more associated energy use, C O 2, CO, N O 2, particulate matter, S O 2, and hydrocarbon emissions due to more formwork used, larger transportation impacts due to a larger mass of materials, and longer equipment use due to the longer installation process. In contrast, the steel-frame construction ...
