What is the Vibrator Machine for Concrete

How much do you know about vibrator machine for concrete? In this paper, according to the different physical properties of each component of vibrator machine for concrete, you will have a clearer understanding of the vibrator machine for concrete,a finite element simulation is used to build a mechanical constitutive model for the vibrator machine for concrete.The variation rules of mechanical information are obtained and studied.

Consolidating and compacting freshly placed concrete with vibrator machine for concrete is a fairly simple and straightforward process. However, precast concrete manufacturers are continually spending unnecessary amounts of time and money repairing defects often associated with the improper use of vibrator machine for concrete. A majority of honeycombing, rock pockets, bug holes, sand streaks, pour lines and voids can be avoided by taking the time to properly train and educate employees on the proper use of vibrator machine for concrete and the future problems that may arise from incorrect vibration practices.

Let’s have a look at the working principle of vibrator machine for concrete. Consolidating and compacting freshly placed concrete with vibrator machine for concrete is a fairly simple and straightforward process.However, precast concrete manufacturers are continually spending unnecessary amounts of time and money repairing defects often associated with the improper use vibrator machine for concrete. A majority of honeycombing, rock pockets,bug holes, sand streaks, pour lines and voids can be avoided by taking the time to properly train and educate employees on the proper use of internal vibrators and the future problems that may arise from incorrect vibration practices.

In general the two most common mistakes made when using an internal vibrator are removing the vibrator head too quickly and dragging the vibrator head through the concrete. Both of these practices often seem like logical shortcuts to the untrained individual, while the trained individual will understand that simply leveling the concrete will not remove entrapped air voids, bugholes and honeycombing. The trained individual will also realize that dragging a vibrator through the concrete will form a mortar channel in the concrete,creating a structurally weak area in the finished product.

When training individuals on the proper use of internal vibrators, it is important to explain the basic principals of how an internal vibrator works. Simply put, vibratory impulses liquefy the mortar, drastically reducing the internal friction between aggregate particles. The mixture becomes unstable, allowing entrapped air to rise to the surface while the heavier aggregates settle under the force of gravity into a dense matrix.

Smaller-diameter vibrators will have higher frequencies and lower amplitudes, while larger-diameter vibrators will have lower frequencies and higher amplitudes. As a general rule, the diameter of the vibrator machine for concrete should be a quarter of the wall thickness of the product being cast. Smaller-diameter internal vibrators with higher frequencies are typically used for consolidating higher-slump concretes used in manufactured concrete products.

When using internal vibrators it is important to lower the vibrator vertically into the concrete, allowing the head to descend under its own weight. Internal vibrators should not be forced down into the concrete. The vibrator head should penetrate previously placed lifts of concrete by 6 inches (150mm). If there is a considerable amount of time lapse between the placement of subsequent lifts, it may be necessary to revibrate the previous lift prior to placing additional concrete to minimize the potential for pour lines and cold joints.
