Abstract:
Finishing lightweight concrete floors may seem needlessly complex. However, avoiding the dangers of overworking such floors can be simple when contractors use proper finishing techniques and the right tools, and maintain a proper finish window. The article discusses these topics as well as characteristics of lightweight aggregate and lightweight concrete mixtures.
