Basic knowledge and design installation of GRC products

The GRC product, Glass-fiber Reinforced Composite, is called glass fiber reinforced composite material. GRC is the main material for low-alkali sulfur (iron)-aluminate special cements used for gelling, and high-zirconia-resistant (alkali-resistant) alkali-glass fiber cloths and filaments as main reinforcement materials, supplemented with other formulation data and admixtures. , Pre-embedded into a reasonable device embedded parts, relying on the mold after the mechanical eruption, pre-mixed, network sizing sizing, mixing and other processes once eruption of a high-strength anti-aging composite data.

GRC skills originated in European and American countries in the 1960s. At the beginning of the development of GRC skills, due to its outstanding physical functions, people gave expectations for GRC data. At this time, E-Glass was used in the GRC data. This fiber was originally used for plastic products and it was appropriately successful. However, because cement is an alkaline material, alkali-free glass fibers that do not have alkali resistance function have been corroded for a long time in the alkaline environment of cement products, making the GRC products function rapidly and failing to ensure the durability of GRC products. And security. This problem severely restricted the application and development of GRC data.

In the 1970s, the joint development of alkali-resistant glass fiber-reinforced Portland cement products by the UK's Construction Research Institute (BRE) and Pilkigton Glass Company (Pilkigton). The birth of alkali-resistant glass fiber successfully solved the durability problem of GRC products and made GRC reborn.

In 1970, the French bank's Raynais Credit Tower, which is located in London, is still standing on the streets of London. Should then be gradually extended to Japan, the United States, Germany, the Netherlands, Spain, Italy, China, Singapore, Romania and more than 40 countries, including more than 500 companies have obtained licenses for the production of GRC products.

GRC data composition and characteristics

Primary color GRC: from river sand, gray cement, alkali-resistant glass fiber, admixture.

Color GRC: Quartz sand, white cement, alkali-resistant glass fiber, admixture.

The characteristics of GRC: unlimited plasticity, arbitrary art form, complete the planner's dream of planning. Environmental protection, sound insulation, earthquake resistance, renewable, without radioactive nuclear elements. Sound-absorbing and sound-absorbing, light weight, high strength and impact resistance.

Fireproof and moisture proof, A1 class fireproof data, resistant to soaking.

Weather resistance, data wet and dry deformation of less than 0.123%, weather resistance and sunshine.

The advantages of GRC: light weight, high strength, good resistance to freezing and thawing, weight 15~40KG, compressive strength 40Mpa, anti-bend 34Mpa, rich color, selection of homogenous core mineral material, can be customized according to the need of color modeling, good texture, Texture, sandblasting surface, litchi surface, smooth and other texture, strip, hollow, relief and other textures. Device is convenient, short cycle, can be produced block cutting, the device is simple, factory prefabricated, can shorten the duration.
