evelopment and application of GRC (glass fiber reinforced cement) at home and abroad

The application of GRC products in construction began in the early 1970s, when the British architectural research institute and Pilkington Glass Company conducted experiments on alkali-resistant glass fiber reinforced cement products. Then in 1966, the British invented the alkali-resistant glass fiber and put it into practical use. The glass fiber is called "cem-fi", which contains zirconia, which slows down and prevents the alkali in the cement from corroding the glass fiber, and then guarantees the durability of the GRC product. The invention and use of alkali-resistant glass fibers is the starting point for the large-scale application of GRC products in practical buildings.

Subsequently, the production technology of GRC products was slowly introduced to more than 40 countries around the world such as the United States, Japan, the Netherlands, Spain, China, Germany, Italy, and Singapore. According to statistics, in recent years, more than 600 companies around the world are engaged in the research and production of GRC materials and GRC products.

Development of GRC products in China

The prototype of GRC materials and GRC products in China is similar to asbestos tile. In the early stage of liberation, when Chinese steel was lacking and there were not many woods, the varieties and application plans of reinforced concrete products were expanded, and it was possible to replace steel with reinforced concrete products. And wood. This was later the “three generations” policy of replacing steel, wood and cotton yarn with cement products, glass fiber and glass fiber reinforced plastic.

China's research on GRC materials and products began in the late 1950s. At that time, there were many technicians who promoted GRC materials and GRC products, but at that time, alkali-resistant glass fibers did not appear, and only alkali-resistant glass fibers could be used in GRC products. This results in a rapid decline in the strength of the GRC product, and there is no guarantee of safety and durability. Therefore, the country once issued a document to disable the application of GRC products. It was not until the mid-1970s that China resumed research and application of GRC materials and GRC products. On the one hand, the development of alkali-resistant glass fiber, on the other hand, the development of low-alkalinity cement. These two aspects of research and development have played a role in the mid-1980s. Then GRC materials entered the field of application from scratch in China and were promoted by the big plan in the 1990s.

Nowadays, China has become a huge market for GRC materials and GRC products. There are nearly 1,000 units engaged in research and production of GRC materials and products, covering 31 provinces, municipalities and autonomous regions across the country, touching buildings, civil engineering, farming and animal husbandry. In the fields of fisheries, environmental art and military engineering.

GRC materials and GRC components are characterized by environmental protection and long-lasting quality, while the GRC components are rich in shape and color. So what can GRC do? The most common GRC components include columns, decorative lines, doors and windows, fences, garden supplies, urban sculptures, etc. GRC can also be used as curtain walls, imitation sandstone, and cement to shape a variety of shapes. GRC is used in a wide range of applications because of its inherently malleable nature, and it can be used outdoors or in wet places no matter what it does!
