Impact of Vibration on Curing and Strength of Concrete

In addition, vibration seems to have different impacts on different properties of concrete. The same level of vibration can change the compressive strength of concrete by up to 13%, while reduces the tensile strength of concrete by 7%. Based on a study of vibration from highway traffic, the amplitude of vibration seems to be a more important factor than the frequency in causing damage. While a vibration of two Hz and three mm amplitude and a vibration …

What's the Best Concrete Screed for the Job? | Concrete ...

Laser-guided screeds are great for jobs that require high flatness specifications. Set up as a laser-guided arm on a relatively small machine, they’re capable of precision level concrete with minimal labor. Crews get concrete somewhat close to grade and laser-guided screeds will level to a precision grade from there.

2. Consolidate the concrete by inserting the vibrator vertically along the centerline at intervals not exceeding 150 mm (6 in.). Take care to not over-vibrate, and withdraw the vibrator slowly to avoid large voids. Do not contact the bottom or sides of the mold with the vibrator. 3. After vibrating, strike the mold 10 to 15 times with the mallet. 4. Strike off to a flat surface using a float or trowel and begin initial curing.
