معرفی مواد بکاررفته در ترکیب GFRC :
The GFRC product includes the following materials, each of which we introduce and state the amount of use of each material in the main composition of the product:
A) Concrete:
In the view of GFRC (Glass Fiber Reinforced Concrete), concrete is one of the main and important components used in the formation of this product. Concrete is a composite material of several important additives that acts as a sticky and resistant matrix. In GFRC, concrete acts as the binder matrix, usually consisting of Portland cement, sand, and sand. But in GFRC, special additives such as white cement and polymers are added to concrete to increase flexibility and resistance to cracking. The concrete used in this industry consists of the following materials: 1. Cement: Portland cement is used as one of the main components of GFRC concrete. This type of cement is used as an important adhesive material to combine other materials.
1-. Sand: Sand is a non-calcareous material that is used as the main raw material of concrete. The size and type of gravel may vary in the production of GFRC and may vary depending on project requirements.
2. coarse sand: coarse sandis also very important as a raw material and is used in the formation of GFRC concrete. Like gravel, the type and size of sand may vary.
3. Polymers: Polymers are added to concrete as additives to increase flexibility and resistance to cracking. These polymers are usually epoxy, acrylic or polyvinyl ester type.
As for the percentage of GFRC concrete ingredients, these values may vary depending on the specific mix used and project requirements. However, in general, the concrete in GFRC usually constitutes about 10% to 15% of the total mix weight. This percentage may change depending on the exact composition of materials, the use of polymers and glass fibers.
It is necessary to repeat that the type of concrete used in GFRC is known as ordinary Portland concrete, which consists of Portland cement, gravel, sand and polymers as its main components. But the exact composition and ratio of these materials may be adjusted for each specific project to meet the design and strength requirements.
b) Glass fibers
Glass fiber is a reinforcing fiber made of molten glass and is used in various industries to strengthen consumables. These fibers are produced by stretching hot glass in the form of long and thin fibers. In the GFRC (Glass Fiber Reinforced Concrete) industry, glass fibers are also used as reinforcement, glass fibers are added to concrete to increase the tensile and impact resistance of concrete. These fibers can come in different sizes and shapes and act as reinforcements for concrete.
The type of glass fibers usually used in GFRC is "AR" (Alkali Resistant) or also called "E-Glass". This type of glass fibers have resistance to alkalis in concrete and since concrete contains alkali cement, AR fibers can be subject to degradation.
The percentage of fibers in the GFRC product may vary and change depending on the project needs and desired properties. However, in general, the percentage of glass fibers in GFRC is usually between 2% and 5% of the total weight of the GFRC concrete mix. This percentage is usually added to increase the cracking resistance and strengthen the concrete for impact resistance and flexibility. Changes in this percentage may be applied depending on the type of project, the need for strength and mechanical properties, and the type of fibers used.
C) Polymers:
Polymers are used as additives in the composition of glass fiber reinforced concrete (GFRC). These polymers are added to the concrete mix to improve mechanical properties, ductility, and resistance to cracking. Polymers are usually added to the concrete mix at two times:
1. When preparing the mixture: Polymers are added directly to the mixture as one of the components of the concrete mixture from the beginning of the preparation of the mixture. These polymers are mixed together with cement and other raw materials as one of the liquid materials used in the mixture. This process helps to combine and bind the materials together.
2. When preparing the final product: In some cases, polymers are added as a surface coating on the final product. This coating can give GFRC products a protective and beautiful coating. These polymers are added to the product as a final coating after the mixture is condensed.
The percentage of polymers used is also variable and may change depending on project needs and product specifications. Generally, the percentage of polymer is usually around 1% to 3% of the total weight of the GFRC concrete mix. This value may be adjusted based on the design requirements, the desired mechanical resistance and the characteristics of the polymer material used. The polymers used are usually acrylic or polyvinyl ester polymers, which act as additives to create flexibility, crack resistance, and improve surface properties in the GFRC product.
d) dyes
Colorants are added to concrete to create diversity in the design and decoration of the GFRC facade. Colorants are one of the important components in the production of GFRC (Glass Fiber Reinforced Concrete) products, which allow designers and manufacturers to decorate their products with different colors and textures. . These dyes are added as special pigments to the GFRC concrete mix. Financially, the price of colorants is variable and depends on various factors such as the type of pigment, the manufacturer's brand, and the amount used.
The types of colorants usually used for GFRC products are:
1. Pigment powders: These powders are usually used as primary colorants. They are available in a variety of colors and are added to the GFRC concrete mix.
2. Liquid paints: Liquid paints are used as color additives to decorate the final surfaces of GFRC products. These colors can be a combination of pigments and special resins.
To incorporate colorants in GFRC concrete mix, the following methods are usually used:
1. Combination with raw materials: Pigment powders are usually added as one of the raw materials in the preparation stage of GFRC concrete mix. This step allows the color to be evenly distributed throughout the mixture.
2. Surface decoration: Liquid paints are applied as a final coating on the GFRC product. This coating is given directly on the surface of the product by spraying or palette to decorate the final appearance.
The amount of dyes used depends on the amount needed to produce the desired color and decoration of the product. Determining the exact amount of consumption should be based on the specific needs of each project and the experience of the manufacturer. Factors such as the amount of GFRC concrete mix and the type of colorant affect this determination.
The percentage of common compounds in GFRC concrete mix is as follows:
1. Cement: usually about 10% to 15% of the total weight of the GFRC concrete mix.
2. Sand: About 40% to 50% of the total weight of the GFRC concrete mix.
3. coarse sand: About 25% to 35% of the total weight of the GFRC concrete mix.
4. Glass fibers: usually about 2% to 5% of the total weight of the GFRC concrete mix.
5. Polymers: usually about 1% to 3% of the total weight of the GFRC concrete mix.
6. Colorants: The amount of colorants depends on design and decoration needs and usually make up smaller percentages of the total weight of the GFRC concrete mix.
Please consider these values as a general reference and you may have more specific needs and different combinations for your specific projects.
