Vibration of concrete, Vibration Methods, FAQs
Vibration helps in minimizing the internal friction by randomizing the concrete mixture. Vibration rearranges the cement and aggregate particles in concrete; this helps concrete in achieving the close configuration. Close configuration expels the water voids and air pockets in the mixture and results in a dense and compact mass of concrete.
