GRC decorative lines have become a common decorative component in GRC buildings, so what is GRC decorative lines on earth? What are the characteristics of GRC decorative lines and what are the construction points of GRC decorative lines?

What is GRC decorative line

1、 What is GRC trim? Hainan GRC component

The GRC of GRC decorative line is the abbreviation of Glass Fiber Reinforced Cement. The galvanometer is a new composite material invented abroad in the 1970s. It uses alkali resistant glass fiber as reinforcement. One of the obvious advantages of alkali resistant glass fiber as reinforcement is that its tensile strength is very high, about 5 times higher than that of steel bars. The standard value of tensile strength of grade 1 reinforcement is 235Mpa, while the tensile strength of glass fiber bundle used in GRC is at least 1400Mpa.

Second, GRC decorative line features:

Due to the high strength of glass fiber, a very thin section can withstand a large tension. In addition, glass fiber does not need a protective layer of a certain thickness like steel bars to prevent corrosion. Therefore, GRC can be made into thin-walled GRC decorative lines. This is a very prominent feature of the wide application of GRC decorative lines.

Sulphoaluminate low alkalinity cement is a new type of inorganic composite material, which is used as binder and mixed with suitable aggregates to form a base material.

It integrates light weight, high strength, high toughness, water resistance, non combustion, sound insulation, heat insulation, corrosion resistance, easy processing and other characteristics, and occupies a unique position in architecture. In recent years, China has introduced GRC decorative line technology to a new stage of development.

Third, GRC decorative line application:

GRC decorative line technology can produce hundreds of varieties of Roman columns, eaves lines, waist lines, door jambs, window jambs, roof jambs, window side columns, light partition boards, pressure swing flues, railings, sandblasting machines, garden reliefs, Tibetan components, antique components, sweat rooms, mountain flowers, colonnades, cultural stones, etc. GRC decorative lines have a smooth and delicate appearance, smooth and realistic patterns, perfect styling, and strong artistic sense. Convenient construction and installation, short construction period. All kinds of GRC decorative line prefabricated components produced have good affinity with cement.

GRC decorative line is also a kind of European style decorative modeling line, which is generally used outdoors to increase the overall outdoor beauty of the house. It is faster and more convenient than cement prefabrication or cast-in-place, but also saves labor, materials and labor; Moreover, it is more standardized and standard. Because the effect of painting or coating on installed GRC decorative lines is similar to that of marble, GRC decorative lines have been widely replaced by marble lines. This kind of pre product is a good choice. Hainan GRC component

Fourth, construction points of grc decorative line:

1. According to the construction drawings, snap the positioning line (centerline or sideline) at the position where GRC components are to be installed. When pasting grc components, the grid cloth should be turned over. If there are special circumstances, it can be directly pasted without turning over. The thin layer full bonding method is adopted for pasting, and the EPS component is forced to overflow the mortar from the periphery, and the width of the bonding joint is not more than 3mm. The bonding joint shall be hooked as it is glued, the mortar joint shall be full, and the EPS component surface shall be kept clean.

2. For larger grc members, support is required for temporary fixation during installation. During installation, if splicing is required, the assembly size and angle shall be measured in advance, and pre assembly shall be carried out at a flat place, with the gap no more than 3mm. The bonding mortar is used as the bonding material for splicing, and the mortar consistency can be greater. The thin layer full bonding method is used. When splicing, it is required to squeeze and hammer slightly and evenly to make the mortar joint meet the requirements.

3. After splicing, the mortar joint shall be leveled with a mortar knife to make the grc components become one. After drying, sand paper can be used to polish if there is excess bonding mortar left at the seam of grc component. After drying, the special anti cracking adhesive at the splicing part of grc components shall be treated. See the instructions for special anti crack adhesive for treatment methods. Pay attention to the finished product protection of grc components after construction, and it is strictly prohibited to pedal or hit by heavy objects. In case of damage, the whole EPS component shall be removed and reinstalled.

What is GRC decorative line and the characteristics and construction points of GRC decorative line are shared here. GRC decorative line has a smooth and delicate appearance, smooth and realistic patterns, perfect styling and strong artistic sense. The construction and installation are convenient, and the construction period is short. All kinds of GRC decorative line prefabricated components produced have good affinity with cement.
