DEG aluminium paste is indeed a material that plays an important role in the production of lightweight concrete
The main component of DEG aluminium paste is aluminium flakes, which are mixed in a mixer to form a homogeneous slurry. These pastes have an aluminium content of up to 70-80%, turning them into efficient lightweight concrete additives. The lightweight nature of aluminium significantly reduces the density of the concrete, which in turn improves its thermal and insulation properties.
A distinctive feature of DEG aluminium paste is that it is moisture-free. This is mainly due to the use of diethylene glycol (DEG) in the production process, which is a highly soluble and safe organic solution that prevents the depletion of water in aluminium pastes. As a result, DEG aluminium pastes are less susceptible to mould growth during storage and maintain a long expiry date even at high temperatures.
DEG aluminium pastes have special advantages in hot climates. Due to the high temperatures and humidity in such areas, mould often grows during storage and transportation of conventional aluminium pastes containing water, which can lead to reduced performance or even render them unusable. Because DEG aluminium paste does not contain water, it can be maintained for a long time in all kinds of harsh environments, ensuring a smooth lightweight concrete production process.
DEG aluminium paste as an efficient and stable lightweight concrete additive has significant advantages in areas with hot climates. Its extensive use not only improves the concrete performance, but also reduces the cost and promotes the steady development of the lightweight concrete industry.
DEG aluminium paste is a new type of building aid consisting of aluminium powder, diethylene glycol (DEG) and other additives. Compared with ordinary aerated aluminium paste, DEG aluminium paste has the following advantages:
Uniform aeration, no mould collapse phenomenon: DEG aluminium paste can effectively control the activity of aluminium powder so that it can be uniformly aerated in concrete, avoiding the mould collapse phenomenon.
Extremely high bulk density, small and dense pores: DEG aluminium paste can produce a large number of fine pores to improve the bulk density and strength of concrete.
A full range of products from coarse to fine particle sizes to meet the needs of different production processes.

The production process of aerated aluminum paste (slurry)/powder is crucial in determining the final product’s quality and performance. This chapter will detail the production flow, key technologies, and control points of each stage in the manufacturing process of aerated aluminum paste (slurry)/powder to help readers better understand the manufacturing of this critical material.
The production flow of aerated aluminum paste (slurry)/powder typically includes the following main steps:
Before production begins, the selection and Preparation of raw materials are crucial. The main raw materials include aluminum powder, additives (such as DEG, dispersants, etc.), and other ingredients. The selection of aluminum powder is usually based on its particle size, activity, and purity. Highly active aluminum powder can generate more hydrogen gas when reacting with water, thus achieving better gas generation effects. The selection of additives needs to consider their role in the aerated aluminum paste, such as improving fluidity and enhancing reactivity.
The prepared aluminum powder and additives are mixed in a certain proportion. This step usually uses high-efficiency mixing equipment to ensure uniform component distribution and avoid agglomeration. The mixing time and speed must be strictly controlled during the mixing process to ensure a sufficient combination of aluminum powder and additives, laying a good foundation for subsequent reactions.
The mixed materials need to be ground to reach the specified particle size. This step is crucial for improving the activity of the aluminum powder. Using ball mills or other types of grinding equipment can effectively reduce the particle size and increase the surface area of the aluminum powder, thereby enhancing its reactivity with water. After grinding, the materials must also be classified to ensure particle size and product distribution consistency.
In this step, the ground aluminum powder is mixed with water and other necessary additives to form the aluminum paste. The reaction conditions at this time (such as temperature and stirring speed) need to be controlled to ensure that the reaction between aluminum powder and water is sufficient to generate a stable bubble structure. Better gas generation effect and fluidity can be obtained through reasonable proportioning and stirring.
The prepared aerated aluminum paste (slurry) must pay attention to environmental conditions during storage and transportation, avoiding high temperatures and humidity to prevent premature reaction and failure. Its physical and chemical properties should be checked regularly during storage to ensure stable product quality. Finally, the aluminum paste must be packaged according to standards to ensure no leakage or deterioration occurs during transportation.
In the production process of aerated aluminum paste (slurry)/powder, several key technologies have a profound impact on the performance and quality of the final product:
Ball milling is an important technology for grinding aluminum powder. The physical grinding process can effectively reduce the particle size of the aluminum powder and increase its specific surface area. Smaller particle sizes help enhance the reactivity of the aluminum powder, allowing it to generate hydrogen gas more rapidly when reacting with water, thereby forming a uniform and stable bubble structure.
Classification technology plays an important role in ensuring the consistency of the particle size distribution of aluminum powder. Through classification, aluminum powders of different particle sizes can be separated, improving the activity and adaptability of the material. A suitable particle size distribution can optimize bubble formation and enhance aerated concrete’s strength and thermal insulation performance.
In the preparation process of aluminum paste, controlling reaction conditions (such as temperature and time) is crucial. Reasonable reaction conditions can ensure that the reaction between aluminum powder and water is sufficient to generate an adequate number of evenly distributed bubbles. The application of reaction control technology helps to improve the stability and consistency of the product.
Product performance can be improved by continuously optimizing the formulation of aluminum paste (slurry). For example, adding appropriate amounts of certain additives can increase the aluminum powder’s reaction rate and improve the aluminum paste’s fluidity and stability. In addition, for different application needs, enterprises can develop various types of aluminum paste to meet the market’s diverse needs.
In production, controlling environmental conditions (such as temperature and humidity) is also crucial to ensure product quality. Especially in the storage and transportation stages, it is necessary to provide suitable environmental conditions to prevent the aluminum paste from failing or deteriorating due to environmental changes.
Quality control is an important link throughout the production process to ensure the stable performance of aerated aluminum paste (slurry)/powder. Enterprises usually establish a complete quality management system, including:
Before production begins, all raw materials must undergo strict quality inspection to ensure they meet production standards. The aluminum powder’s activity, purity, and particle size distribution need to be tested to determine whether it meets the production requirements.
During the production process, the parameters of each stage (such as temperature, humidity, mixing time, etc.) are monitored in real-time to ensure that the production process is always in the best state. In addition, online testing equipment can detect and adjust problems in time to prevent the generation of unqualified products.
After the product is produced, comprehensive performance testing of the finished product is required, including indicators such as fluidity, gas generation, and compressive strength, to ensure that it meets relevant standards and customer needs. Only products that have passed strict testing can be put on the market for sale.
