2 Reasons Why Using a Concrete Vibrator Is Vital after Pouring Cement
If you own a construction company, you may have an upcoming job that will require the use of cement. Even if you have used concrete before during your projects, you may be wondering if there is anything you and/or your workers can do to create a smoother finish once the cement sets and cures.
If so, consider using a concrete vibrator after the cement is poured and starts to set. Not only do the vibrations smooth and even out the surface, but there are a couple of other reasons why using the vibrator is vital after pouring cement.
1. Removes Air Pockets That Create Weak Cavities in the Set-up Concrete
One reason why a vibrator should be used before concrete is allowed to set is that it removes air pockets that can become trapped during the pouring process. Because of its thick, viscous nature, wet cement does not easily allow air to escape once it becomes trapped.
If the air pockets remain, they will create cavities that will cause weak spots in the concrete. Causing a honeycomb effect inside the structure, these spots will cause more rapid deterioration of the finished product. However, if you use equipment that vibrates the wet cement, the air pockets are removed, giving you a stronger structure in the finished product.
2. Packs Together the Aggregate to Create a Higher Density
Another reason why a vibrator should be used after the cement is poured is that it helps to create a higher density in the concrete. While the air pockets are being removed, the aggregate that makes up the wet cement is packed together.
As the aggregate is packed together, the bond between the particles becomes stronger, helping to eliminate weak spots in the concrete. As the cement dries, the packed aggregate serves to create a solid structure that is better able to withstand impact and wear from exposure to weather elements.
When you take the time to use a machine to vibrate the cement before it sets up, it helps to remove air pockets that create cavities that weaken the finished concrete. The vibrations also help to yield a denser product by packing the aggregate together to create a stronger bond. Speak with an industrial and manufacturing supply company that offers concrete vibrators if you have any further questions or need help with choosing one that best serves your construction company's needs.
