Grouting is an important building material that is widely used in various construction projects. Its production equipment, production process and testing methods are essential to ensure the quality and performance of the grout. This article will introduce the production equipment, production process and testing methods of grouting material in detail.
1. Grouting production equipment.
The production equipment of grout mainly includes mixers, transfer pumps, storage tanks, etc.
1.Mixer.
The mixer is the core equipment of grout production, and its function is to fully mix and mix various raw materials to form a uniform grout. In order to ensure the mixing effect and quality, it is necessary to choose an efficient mixer.
2.Transfer pumps.
The function of the transfer pump is to convey the stirred grout material to the storage tank. The selection of a transfer pump should take into account factors such as its conveying capacity, stability and service life of wearing parts.
3.Storage tanks.
The function of the storage tank is to store the stirred grout and ensure its quality and stability during storage. The storage tank should have sufficient capacity and have good sealing performance.
Second, the grouting material production process.
The production process of grout mainly includes the proportioning, mixing, conveying and storage of raw materials.
1.Ratio of raw materials.
The ratio of raw materials is a key link in the production of grout, which directly affects the quality and performance of grout. According to the production needs, various raw materials should be mixed according to the specified proportions.
2.Stir.
The purpose of stirring is to make all kinds of raw materials fully mixed to form a uniform grout. When stirring, the stirring time and speed should be controlled to ensure that the stirring is uniform and does not produce segregation.
3.Conveying and storage.
The purpose of conveying and storage is to ensure the quality and stability of the grout. In the process of conveying, the conveying speed and pressure should be controlled to avoid segregation and blockage. The tightness of the storage tank should be maintained during storage, and the quality and performance of the grout should be checked regularly.
3. Grout testing methods.
In order to ensure the quality and performance of grout, appropriate testing methods should be used for quality inspection and control.
1.Mobility test.
Fluidity test is an important means to detect the flow properties of grout. Through testing, it is possible to understand the slump, expansion and filling properties of the grout, so as to evaluate its workability and flow characteristics.
2.Compressive strength testing.
Compressive strength is one of the important indicators to measure the quality of grout. Through compressive strength testing, it is possible to understand the strength grade and durability of the grout, so as to evaluate its load-bearing capacity and service life in the building structure.
3.Microswelling detection.
Micro expansion detection is an important means to detect the micro expansion performance of grout. Through testing, the volume change of the grout during the hardening process can be understood, so as to evaluate its ability to compensate for the shrinkage stress of concrete and its anti-cracking performance.
4.Chloride content detection.
Chloride ion content detection is an important means to detect chloride ion content in grout. The chloride ion content directly affects the durability and service life of the grout. Through testing, the purity and quality stability of the grout can be understood.
5.Gas content detection.
Gas content detection is an important means to detect the gas content in grout. The level of air content directly affects the construction performance of the grouting material and the compactness after hardening. Through the inspection, the air content of the grout can be understood and adjusted and controlled accordingly.
