What material is the GRC moldings made of?

GRC is the abbreviation of glass fiber reinforced cement in English, which refers to the mixed material of glass fiber reinforced cement.

The basic components of GRC are cement, sand, fiber, and water, and materials such as polymers and admixtures are added to improve the performance of the later stage.

Cement: The cements commonly used in GRC mainly include fast-hardening sulfur aluminate cement, low-alkalinity sulfoaluminate cement, ordinary Portland cement, and white Portland cement.

Fiber: The fibers used in GRC materials must be alkali-resistant glass fibers, including alkali-resistant glass fiber untwisted roving, alkali-resistant glass fiber chopped yarns, and alkali-resistant glass fiber mesh cloth. European and American countries require that the zirconia content of glass fibers used in GRC is not lower, and China requires that the zirconia content is not lower when using ordinary Portland cement.

Polymers: The polymers that are usually added are propylene emulsions, i.e. acrylate copolymer emulsions.

Admixtures: Usually high-efficiency superplasticizers, plasticizers, retarders, early strength agents, antifreeze, rust inhibitors and other admixtures can be selectively added: when the product contains steel reinforcing materials or steel embedded parts, calcium chloride-based admixtures shall not be used.

Other materials: Selectively adding some pozzolana active materials is conducive to improving the comprehensive properties of GRC products, such as strength, impermeability, durability, etc.

At present, the more common GRC products on the market include GRC decorative products (various decorative lines, etc.), GRC exterior wall panels, garden landscape products, lightweight partition panels, GRC insulation boards, permanent tubular core molds for ventilation pipes, permanent templates, industrial building roofing components, sound barriers, self-supporting floors, irrigation channels and pipeline protection channels, etc.

Cement, sand, fiberglass, interior decoration should pay attention to crack prevention.

When decorating a house, you need to understand the specific construction steps and processes. What are the key points of GRC decorative line construction process? PChouse will take you to find out.

Process flow: construction preparation, construction inspection, production of various iron parts and brackets, accurate external wall civil engineering baseline, positioning and pay-off according to GRC construction specifications, GRC construction in place, installation, plugging, repairing, maintenance, and itemized acceptance.

Construction method: 1. Component entry inspection standard.

Since the components are prefabricated outside the perimeter, the quality of the incoming components must be guaranteed. According to the standards of component processing enterprises, on-site inspection is carried out according to the appearance and size deviation, and the factory qualification certificate must be obtained for the construction of the site, and the use of unqualified components is strictly prohibited.

2. Component installation and fixing method.

Line class installation:

When the cross-sectional specification is less than 8mm 8mm, directly on the red brick wall or concrete wall 8 100 expansion bolts and component embedded parts welded and fixed (embedded parts and mold land expansion bolt welding points shall not be less than 4).

When the cross-sectional specification of the line is greater than 800mm 80mm, it is necessary to add angle steel brackets in the eaves line to fix the wall, and then weld and fix the expansion bolts on the wall and the embedded parts of the components.

For the GRC line, I believe that friends have a certain understanding, it is a new type of composite material, mainly with alkali-resistant glass fiber as reinforcement, sulfoaluminate low alkalinity cement as the cementing material and mixed with suitable aggregates to form the substrate, through jetting, vertical mold casting, extrusion, slurry and other processes and made of new inorganic composite materials, so what is the GRC line made of? Let's take a look.

1. Cement. Generally speaking, the cements used in such products mainly include fast-hardening sulfur aluminate cement, low-alkalinity sulfur aluminate cement, ordinary Portland cement, and white Portland cement.

2. Fiber. For the fiber in this kind of product, it must be alkali-resistant glass fiber, and there are many categories, such as alkali-resistant glass fiber untwisted roving, alkali-resistant glass fiber chopped yarn, and alkali-resistant glass fiber mesh cloth; European and American countries require that the zirconia content of glass fibers used in GRC is not lower, and China requires that the zirconia content is not lower when using ordinary Portland cement.

3. Polymers.

The polymer usually added is propylene emulsion, i.e. acrylate copolymer emulsion.

4. Admixtures.

For admixtures, additives such as high-efficiency superplasticizers, early strength agents, antifreeze agents, plasticizers, retarders, rust inhibitors and other additives can be selectively put in; When the product contains steel reinforcement materials or steel embedded parts, calcium chloride-based admixtures shall not be used.

5. Other materials.

Finally, you can also selectively put some pozzolana living materials, which can improve the comprehensive performance of GRC products to a certain extent, such as strength, impermeability, durability, etc.

Summary: Well, the above is about the GRC line used to make the content of the introduction, I hope to provide you with some help, I believe that in the future in the GRC line use what to make the process, friends will be more handy, get their own satisfactory answers.

1. According to the construction drawings, pop up the positioning line (center line or edge line) at the part of the GRC component to be installed.

2. When the GRC component is pasted, the mesh cloth should be turned over, and if there are special circumstances, it can be directly pasted without turning the bag. The thin layer full adhesive method is used for pasting, and the EPS component is squeezed vigorously so that the mortar overflows from the periphery, and the width of the adhesive joint is not more than 3mm. The adhesive joint should be hooked with the adhesive, the ash joint should be full, and the surface of the EPS component should be kept clean and tidy.

3. For larger GRC components, it is required to set up supports for temporary fixation during installation.

4. When installing, if splicing is required, the size and angle of the assembly should be measured in advance, and pre-assembled in a flat place, with a gap of no more than 3mm. The adhesive mortar is used as a splicing bonding material, and the consistency of the mortar can be larger, and the thin layer full adhesion method is adopted. When splicing, it is required to squeeze and hammer slightly and evenly to make the ash seam meet the requirements.

Fifth, after splicing, the ash seam should be hooked with a gray knife to make the GRC component a whole. After drying, if there is excess adhesive mortar left at the joint of the GRC component, sandpaper can be sanded.

6. After drying, the special anti-crack glue for the splicing part of GRC components is treated. The treatment method is described in the instructions for the use of anti-crack special adhesive.

7. After the construction of GRC components, pay attention to the protection of finished products, and it is strictly forbidden to step on and hit by heavy objects. If there is any damage, Ganzhou should remove the whole EPS component and reinstall it.
