Concrete pump has now become an indispensable member of engineering construction. In addition to the promotion of urban and rural construction, its own advantages are also very obvious, reducing labor force, shortening construction period, and improving project progress efficiency. The correct use of the concrete pump can not only improve the work efficiency, but also avoid the blockage of the concrete pump. Common concrete pump easily blocked positions and elimination methods are as follows:

Requirements for concrete slump in fine stone concrete pumping
When the concrete with a slump of 10-15 cm is dumped into the hopper, its surface is easily broken; when the slump is less than 10 cm, the concrete is completely broken after tilting, and has a serrated edge, which breaks vertically. into thick blocks;

To improve the pumpability of concrete, it is necessary to increase the amount of cement, use a larger water-cement ratio and sand ratio, and use a stricter aggregate gradation, which means an increase in cost or a decrease in quality. A more economical and effective way is to use admixtures to improve the pumpability of concrete. There are many types of additives, among which the admixtures that can improve the pumpability of concrete include air-entraining agents,

The maintenance before and after use of the wet spraying machine requires frequent maintenance, so as to maintain its high performance, as smooth as new, reduce the number of failures, and bring greater benefits to the company. The same goes for wet sprayers. As the most advanced shotcrete support equipment in China, the concrete wet shotcrete machine has a wide range of uses, and the construction environment is also extremely complex,

Requirements for Cement Conveyed by Fine Stone Concrete Pump
1. Reduce the frictional resistance of the mechanical part of the concrete with the pump, the conveying pipeline and the interior of the concrete and have good fluidity.
