唐山GFRC

The original materials used in the manufacture of products such as GFRC curtain wall panels must comply with the following specifications in order to ensure the quality of the products.

Cement: Portland cement in accordance with ASTM C150;、

Fiberglass: Meets the PCI-MNL-130 specification with a minimum zirconia content of 16%;

Silica sand: In accordance with BSEN 812 Section 103.1:1985, Silica> 96%, Cl-Ion ≤ 600ppm, Loss on ignition max. 0.5%, All particles pass 1.2mm sieve, and fine particles can pass 0.15mm sieve is limited to a maximum of 10 %;

Buried parts: Buried parts shall comply with the relevant requirements of ASTM A1011 or A1008;

Admixtures: Meet ASTM C494 requirements for Types A, B, D, F, and G or ASTM C260, metakaolin used as an admixture, or other information in accordance with ASTM C618 requirements, colorful pigments and white pigments in accordance with ASTM C979 , Poly House maintenance agent can replace water maintenance, in line with PCI-MNL-130 rules.

The production and use of GFRC began in the early 1970s. The joint development of alkali-resistant glass fiber-reinforced Portland cement products was first carried out by the UK's construction and research organization and Pilkington Brothers. Then it gradually expanded to more than 40 countries including Japan, the United States, Germany, the Netherlands, Spain, Italy, China, Singapore and Romania. Through decades of time, GFRC has experienced sophisticated specifications, process technology, and quality (see International Standards such as BSEN/ASTM/PCI, etc.). Although there are industry norms in China, they are similar to nothing because of the interests driven and the supervision they perform. Although there are thousands of manufacturers, they are all methods of the local economy. They only focus on capital and profit. Well, the foundation does not pay attention to the intrinsic quality (physical properties) of the product, using inferior materials, cutting corners, and even using steel bars to replace high-cost alkali-resistant glass fiber, resulting in a long service life of several years, at any time due to aging corrosion cracking The risk of falling. The GFRC products manufactured by the current specification process have excellent physical properties and can be built with the same life span.
