What is a concrete pump?
Concrete pump is a device that is responsible for transferring concrete from the mixer to the desired location with the help of a pipe. In fact, in various industries, the best, fastest and most accurate method for transferring and moving materials, especially concrete, is pumping, which does not even matter the type of access route. For this reason, all pumps, from small to large concrete pumps, are extremely important in construction projects.
Concrete pump
Concrete pumps work in different ways that result in pumping cement mixtures. The most common operating mechanism of concrete pumps is suction and discharge. You must know that concrete has a very high viscosity and is a combination of heavy, hard and even large pieces. Therefore, if there is no movement, the concrete mixture will harden quickly and its movement will be disturbed. Concrete pumps, according to the technical characteristics of this cement mixture, with a continuous entry and exit mechanism from its hardening in They prevent during transmission. Also, it is not bad to know that the working mechanism of concrete pumps is slightly different from each other based on their structure, which includes two-cylinder piston pumps, etc.
Concrete pump and tips you need to know about
A professional operator must be used to work with the fine concrete pump that is used in various industries and projects. Important points to keep in mind for working with these devices are:
The output pressure of the concrete should be calculated based on the diameter and thickness of the pipe so that the weak connections do not break apart and irreparable damage is not caused.
The diameter of the pipe should be at least 3 should be equal.
Flexible pipes reduce the pressure of the concrete mixture.
Aluminum pipes should not be used for concreting with a pump because aluminum material reacts with cement and As a result of the release of hydrogen gas, the strength of the concrete mixture decreases by 50%.
If there are air bubbles in the concrete structure, the maximum concrete pumping area should be 45 meters.
The most suitable slump for pumping is between 4 and 10 cm.
If there is light and ordinary aggregate in the concrete structure, lubricant additives should be used.
After the completion of the project, Several ball-shaped balls should be sent into the path of the pipes so that they are completely cleaned, and even empty water and air pumping can be used, which is required to do one of these two methods.
