How To Weigh The Vibration Viscosity Of The Rubber Paver Machine

Vibration viscosity is a trade-off criterion in the construction of the rubber paver machine. It has an important impact on the construction quality. However, in practice, there are often some reasons to affect the vibration viscosity. The large particle size is larger when the original data and the mix ratio are the same as other elements. As the particle size increases, the vibration viscosity coefficient decreases; the slump increases.

If the particle size is too large, fresh concrete is easier to tap, but the cohesiveness becomes worse, and it is easy to slush, layer, and chamfer during vibration. At the same time, the slumping degree becomes smaller, and it is easier to form a sag. Unit water consumption The unit water consumption has a strong influence on the vibration viscosity coefficient of the fresh concrete of the concrete paver. With the increase of the unit water consumption, the vibration viscosity coefficient of the fresh concrete drops significantly. The relationship between the two is only an exponential relationship.

Crushed stone concrete reduces faster than gravel concrete, has a larger unit water consumption, and the difference between the two types of concrete is very small. It can be seen that as long as the vibration viscosity coefficient can accurately reflect the quantitative influence of the rough aggregate's surface angle and roughness characteristics on the tap performance of fresh concrete, the amount of cement is less than 290kg under the premise of the same water-cement ratio. Dosage; vibration viscosity coefficient rises.

If the amount of cement is greater than 290kg, increasing the amount of cement will reduce the vibration viscosity coefficient, but the absolute value of the impact is small. When the water-cement ratio is the same, if the cement dosage is changed, the slump reflects the opposite, but it is not sensitive. This indicates that the vibration viscosity coefficient reflects the thickness of the cement slurry that provides the tapping effect, but under the same conditions, the static slump is more difficult to reflect this tapping difference.
