Why does the concrete tanker rotate?

On the road, we can often see a slowly rotating "big roller" driving in the traffic flow-that is, the concrete mixer truck.

rotation," In order to prevent concrete from becoming "stone"

, concrete is a building material made of cement, admixture, aggregate, admixture and water in a certain proportion. At rest for a long time, these components are prone to "segregation", that is, "separation of slurry and bone": the heavier aggregate sinks and the cement slurry rises.

Aggregate sinks and paste rises

If it is not mixed during transportation, the concrete may begin to set before arriving at the construction site, which will seriously affect the construction performance and mechanical properties of the concrete.

concrete is the difference in slump height of the concrete mixture due to its own weight.". This is an important index to measure the fluidity of concrete. If the slump is too large or too small, it will affect the quality of the project. If the slump is too small, it will lead to difficult pouring of concrete. If the slump is too large, it will lead to poor uniformity of concrete, poor construction performance, and affect the apparent quality of concrete entities.

Epilogue:

a little spin, Behind it is the crystallization of material science and engineering wisdom. It is this seemingly simple mechanical movement that ensures the quality stability of concrete from factory to pouring, and lays a solid and reliable foundation for the high-rise buildings we live in and the roads we drive on. Next time, when you meet the slowly rotating "big roller" on the road, you may have a better understanding of this ordinary scene: it is not only transportation, but also a material preservation action racing against time.
