What are the common problems with cement mortar pipe moistening?

Ready-mixed concrete must be moistened and lubricated before starting the pump. For the past few decades, the ready-mixed concrete industry across the country has been using water and mortar to moisten pipes, which is costly and wastes materials and vehicles. The lubricant developed by Yulong Materials reduces costs, has good effects, saves water, vehicles and energy, and has good promotion prospects.

Ready-mixed concrete has been promoted in my country for more than 40 years. For decades, pump trucks have been moistened and lubricated with water and mortar before work, so that the pump and pump pipes can be used after being moistened. The inner wall of the pump pipe is lubricated to reduce the friction resistance through the pipe when pumping concrete and ensure smooth pumping.

The water and mortar required for traditional pipe lubrication methods must be transported to the construction site by vehicle. In this way, every time the pump truck arrives at a new construction site, the mixing station must send a concrete transport truck to deliver water and mortar to the project, causing transportation problems. It is a big waste. Generally, each pump truck needs to be replaced at 4-5 construction sites a day, and the supporting water and mortar transport trucks need 8 trips. This not only reduces the utilization rate of the concrete transport trucks, but also consumes this part of the transportation. A certain amount of gasoline.

In order to save vehicles for transporting mortar, some concrete companies also use the method of carrying mortar on the upper part of the concrete truck after loading the concrete. This method saves a vehicle, but it often brings some negative consequences. The consequences are because, in order to prevent the mixing of mortar and concrete, the body of the concrete transport truck with mortar cannot rotate during walking. The bumps along the way will cause concrete delamination, that is, stones, a sink, mortar and cement slurry. When this kind of concrete is transported to the construction site, if the mixing pump truck is not fully mixed and brought into the project, it will cause the shear wall column concrete structure to be delaminated, and the upper part of the structure will have few or even no stones. In severe cases, it will have to be dismantled and reworked.

To sum up, the traditional pipe lubrication method does have certain shortcomings. It not only wastes water, vehicles and gasoline, but also brings project quality problems. For this reason, we started to develop Yulong concrete lubrication method. Tube agent solves your worries. </p
