Two Causes of Concrete Pump Damage
-
Pipeline coordination factors at the construction site
Due to the restriction of the site environment, a considerable part of the concrete pumping construction pipeline is arranged unreasonably, there are too many joints and bends, and the pipeline leaks, resulting in excessive resistance of the pipeline, causing water loss and friction heat generation of the concrete mixture, affecting the pumping efficiency, leading to the loss of workability of the concrete mixture, and causing pump damage. Clink this for more.
Loss of air bubbles in concrete under pump pressure
Under the pumping pressure, the bubbles in the concrete mixture will deform and even break. The reduction of bubbles will cause the "ball" effect to disappear, and the concrete mixture will also show pump damage. Especially when the quality of the air-entraining component in the admixture is not good, there are many large and unstable bubbles which should be stable and small bubbles, and the bubbles will break under the pressure and lose the "lubrication" effect.
