Auxiliary Materials

Auxiliary Materials

There are several types of auxiliary materials that are used in construction. These materials can be classified according to their cost, toughness, and ductility. It is important to determine the proper quantity before starting construction. This method helps minimize waste of these materials. It also helps reduce construction costs. However, there is no definite formula for calculating the right quantity of auxiliary materials.

Groups of auxiliary materials

Auxiliary materials are those used in manufacturing processes and do not form part of the output itself. They are added to basic materials to provide specific properties. These materials are necessary to the production process in ways that affect the basic materials directly, such as equipment service and building maintenance, transportation within the production facility, worker needs, and supply and marketing.

In one embodiment, PVPP and mannitol are combined to form a composite auxiliary material. This material consists of PVPP and mannitol particles, which cocrystallize and form a spherical particle. These materials are not crystalline, so cocrystallization is required to achieve desired mobility and compressibility.


Ductility of auxiliary materials is a property of a material that allows it to be shaped to different shapes. For example, an aluminum alloy’s ductility depends on the heat treatment that the metal has received. Different heat treatments increase the hardness of aluminum and decrease its ductility.

The degree of ductility of a material is measured in percent elongation after fracture or the number of bends that can be made. The first method involves taking the information directly from the stress-strain curve. The second method involves measuring the reduction in the area of the tensile test specimen. In addition, a cold-bend test is a common way to measure ductility.

The ductility of a material is related to its tensile and compressive strength. Metals with high ductility are gold, silver, and platinum. Those with low ductility are copper and steels containing high amounts of carbon. However, these metals are not as malleable as polymers and ceramics. In addition to tensile and compressive strength, ductility is a key property for metal fabrication.

For the plasma process, the feedstock material has low ductility. It may be a pure metal, an alloy, an intermetallic compound, or a ceramic. Low-ductility materials can be used as feedstock for welding because they have desired material properties, such as fatigue resistance, crack propagation, and corrosion resistance at welding temperatures.


Material toughness is an important quality for materials used in heavy-duty applications. It reflects the material’s ability to absorb energy in a specific way. In ASTM tests, this toughness is measured using a specimen that is deformed by a pendulum. The higher the value of this toughness, the less the material is likely to deform.

The fracture toughness of a material increases with its strength. The curve for different strength levels is almost parallel. For example, higher-strength steels require higher toughness because of the reduced probability factor that occurs when a material undergoes a fracture. The ratio between the material’s toughness and its yield strength must be high for the material to resist fracture.

The newer Al-Li alloys improve their toughness by minimizing tramp element effects. High-purity lithium metal, specialized casting processes, and fluxing are effective in reducing tramp element levels. Other toughening strategies involve minimizing the proportion of constituent phase particles and iron and silicon content. A new alloy developed at the University of Dayton Research Institute is characterized by a lower tramp element content and a higher modulus.


In manufacturing, auxiliary materials are used in conjunction with basic materials to impart specific properties. The auxiliary materials may affect the basic materials directly, for instance in the maintenance of machinery and buildings, worker needs, and transportation within the plant. They may also be used in marketing and supply activities. However, their cost is largely unrelated to the basic materials’ cost. The following are eight common examples of auxiliary materials used in manufacturing.

Production costs associated with auxiliary production include the need for energy, fuel, pipeline losses, and network losses. It also includes the total cost of transportation on the enterprise’s territory. The cost of transportation can be continuous, intermittent, or discontinuous. Some of the major types of transportation are trucking, railways, and automobiles.

The proposed method provides a better way to calculate auxiliary materials in housing construction. It is based on a BIM model that allows for fine management of auxiliary materials. It also incorporates an application called zgBIMs that can calculate the auxiliary material quantities. Experimental results demonstrate that the method reduces auxiliary material waste.

Distinguishing between raw materials and auxiliary materials

In manufacturing processes, a company may use raw materials and auxiliary materials to create its end products. These two types of materials have similar purposes and use, but they are different in many ways. Raw materials are used to create a good or service and are more expensive, but auxiliary materials are much less costly and have little to no impact on the end product’s cost. Knowing the difference between raw materials and auxiliary materials will help you record your inventory and estimate how much of each you need to make your product.

Cost of raw materials

Auxiliary materials are materials needed for production but do not form the main substance of the final output. They are added to basic materials in order to impart specific properties. They also serve a specific purpose, such as in building maintenance, equipment service, or worker needs. Auxiliary materials are also important for transport within a manufacturing plant and for marketing. In some industries, they account for more than 10 percent of the total cost of production.

The cost of auxiliary production includes the costs of energy and fuel. It is also influenced by the use of pipelines and networks. Moreover, the cost of auxiliary production includes the total funds used for transportation within the enterprise’s territory. These funds can be used for internal, external, interdepartmental, or intra-workshop transportation.

These factors influence the cost of raw materials. The risk assessment of raw materials is an important step to ensure that there are adequate supplies. It takes into account geopolitical, technical, and geological factors. It also takes into account the environmental impacts of raw materials.

Cost of auxiliary materials

Auxiliary materials are materials used in manufacturing, but which do not form the main substance of the output. These are added to the basic materials to impart specific properties. In other words, they are necessary to achieve the end results. They can be used for equipment servicing, building maintenance, worker needs, and transportation within the plant. They can also be used for marketing and supply.

In general, these materials are spherical, solid, and free of voids. The composite auxiliary material is a spherical particle with a high mobility. It is typically paired with mannitol and PVPP in a mass ratio of 98:260. Cocrystallization of the two compounds can improve mobility and compressibility. It also can overcome the defect of one material when combined with another.

The proposed BIM-based method can be applied to estimate the costs of auxiliary materials in residential construction. It also presents a model for auxiliary material management. It is implemented using zgBIMs, a BIMs application that allows the calculation of auxiliary materials in a construction project. Experimental results demonstrate that the proposed method can reduce auxiliary material waste.
