China Electric Concrete Vibrator Price

Several specific vibrational best practices

(1) The vibration of most concrete is insufficient or uneven, which is the truth of construction. The best technique for using a built-in vibrator is to recover the vibrator very slowly-speed about 1 inches per second. As long as the concrete vibrator is withdrawn, the foam still appears, requiring more vibration.

(2) In the event of a failure of the first vibrator, spare standby concrete vibrator as standby is prudent.

(3) When pouring low slump concrete, be careful not to vibrate. ("Slump" is a measure of the ease of concrete, because the low slump of concrete is relatively hard, so need more vibration).

(4) When pouring self-compacting concrete, the vibration can be eliminated.

Make sure to penetrate the concrete or multilayered concrete before it has been placed to reduce cold joints. The vibrator shall be at least 6 inches above the front layer. (Cold bonding occurs when a newer layer of concrete is poured into an old layer that has been solidified and hardened enough to prevent two layers of bonding).

(5) The concrete vibrator should be inserted near the vertical direction to maximize its effect.

(6) Don't bend the vibrator too much.

(7) The vibrator shall be kept in the concrete mixture for at least 10 seconds.

(8) The average lift speed of a concrete vibrator shall not exceed three inches per second; usually one inch per second produces the best results.

(9) The concrete vibrating head must be completely immersed in the concrete.

(10) Each time a vibrator is inserted, its radius of action should overlap with the previous radius of action. A good rule of thumb is that the radius of action is four times times the diameter of the vibrator's tip.

(11) Do not open the vibrator until the tip is fully immersed.

(12) For small-scale work, consider using a lightweight portable vibrator.
