Cement is a mixture used to make concrete.Concrete is used for sidewalks, lanes, garden decorations and many other landscape features.Bubbles trapped in a cement mixture can cause pits or pockets in finished concrete works.Bubbles are created by air trapped under coarse deposits in the cement mixture.In order to prevent the pit or pocket, air must be released from below the deposit and allow the air to float to the surface.Layered pour cement.Each layer should be slightly thinner than the tip length on the concrete vibrator.For example, if the tip on the concrete vibrator is 10 inch long, the cement layer should be between 8 and 9 inch thick.Insert the tip of the concrete vibrator into the first layer of cement and open it.Let the vibrator work for 10 to 15 seconds, or until the foam or paste begins to form around the tip of the vibrator.Remove the tip of the concrete vibrator and move 15 to 18 inch from the first insert.Put the tip into the cement, turn it on and let it work for another 10 to 15 seconds.Repeat this process throughout the cement project.The overlapping concrete vibrator tip is inserted, so the insertion distance is not more than 15 to 18 inch from the previous vibrator.Pour the second layer of cement into the first layer of fully vibrating cement.Repeat steps 2 to 4 for your second layer.Make sure that when you insert the tip of the concrete vibrator, the last 2 inch of it will penetrate the previous layer of cement.This will help both layers stick to each other.Repeat the process listed above for each layer of cement you add.Fill in the cement mold or cement form as needed.Place your hand on each side of the mold or shape and gently shake back and forth.Keep shaking for a few minutes or until you see the bubbles reach the surface of the cement.If you are using a wooden, metal or solid plastic mold or shape, tap gently on the side of it with a hammer and vibrate the inner cement.Tap each position for a minute or two, or until you see the bubbles reach the surface of the cement, then select the second position a few inches from the first position and repeat the process.Repeat step 5 around the entire mold or form.
