In this short article, we will talk about the steps and implementation methods in the GRC industry (GRC, GFRC). The view of GRC (GRC, GFRC) usually starts from a new idea and thought. The construction industry and architects are constantly looking for innovation and creativity in the facade of their projects, and this requires powerful materials and diverse methods in the execution of the facade. GRC panels (GRC, GFRC) are designed and produced in a workshop based on the needs of the project, and due to the extraordinary mechanical capabilities of these GRC materials (GRC, GFRC), these parts can be produced in low thickness, various forms and various shapes. and that is why the GRC facade (GRC, GFRC) is favored by architects, employers and investors in the construction industry.
After designing the initial concepts by the architect, it is recommended to consult with an expert and experienced consultant in the field of GRC industry (GRC, GFRC) before entering the next phases and completing the details. This will have an undeniable effect on increasing the quality of the plan and reducing the implementation costs. Completing the concept and the details of the facade will require the exchange of information between the architect and the GRC facade executive (GRC, GFRC).
In the next step, detailed structural calculations including the design of the limited components of the GRC piece (GRC, GFRC) against wind and earthquake loads, the design of installation methods and metal infrastructure are performed, which requires high experience and expertise. It is recommended that these steps be done by expert consultants of GRC facades (GRC, GFRC). Wrong decisions at this stage can cause irreparable costs and problems in the stages of production and implementation of GRC parts (GRC, GFRC).
In the next step, the manufacturers of GRC parts (GRC, GFRC) design and manufacture the required molds. GRC industry (GRC, GFRC) is generally based on molding. Molds are made based on various parameters, including the geometric form of the part, number of parts, dimensions, accuracy and details required in the production of the part and available materials. Today, in most cases, fiberglass molds are used to produce GRC parts (GRC, GFRC), but silicon, wood, and metals can also be used.
GRC (GRC, GFRC) is a cement composite that is produced from the combination of cement, silica, polymers, mineral pigments, water and zirconium coated glass fibers. Material specifications and consumption ratios should be based on BS-EN-15422, BS EN 01169 and international guidelines. Unfortunately, in most cases, the employer’s lack of knowledge about the standards and regulations causes unscrupulous manufacturers to supply them with a non-standard and cheaper product by violating the regulations, which will severely affect the durability and quality of the product. The manufacturer injects GRC materials (GRC, GFRC) into the molds based on the composition criteria or sprays them into the mold with wind pressure. The produced product should be kept according to the mentioned standards for a specified period of time in order to obtain proper resistance and durability before installation in the project.
The installation method of GRC parts (GRC, GFRC) are designed dry based on standards and taking into account regional conditions. These connections are usually made using bolts and nuts that can be controlled and provide the ability to rig in different directions. Before installation, the metal foundation and other connecting parts are resistant to moisture conditions with furnace paint. These connections are usually designed from cans, corners and studs, and it is tried to reduce the bulk of it in the factory as prefabricated and the amount of workshop operations as much as possible.
Due to the significant weight of the GRC, GFRC parts, the installation operation is done with the help of cranes and lifts, and due to the large dimensions of the panels, it has a very good speed. Also, if needed, different work fronts can be defined so that the installation operation can be performed by several specialist teams at the same time. GRC, GFRC facade installation operation will require continuous monitoring, because the wrong installation of GRC, GFRC panels will reduce the life span and possible future risks. The facade of GRC (GRC, GFRC) is finished with the adjustment of the installed parts and their cleaning and delivered to the client.
If you use expert and experienced GRC consultants, producers and executives, using this technique will definitely make you stand out and your project will last over time.
