  • What You Should Know About Vibration Concrete Construction

    The concrete moves tightly against the form and around the reinforcing steel. The mix particles rearrange themselves. The mortar fills the voids between the coarse aggregate particles, and the entrapped air rises to the top of the layer. There are two basic ways to vibrate concrete: internally and externally. In internal vibration

  • What is the problem of over vibration of fresh concrete?

    For proper compaction of concrete by immersion vibrators, the vibrating part of the vibrators should be completely inserted into the concrete. The action of compaction is enhanced by providing a sufficient head of concrete above the vibrating part of the vibrators. This serves to push down and subject the fresh concrete to
