Production of GRC sheet, what are the requirements for major raw materials?

Source: Production of GRC sheet, what are the requirements for major raw materials?

The main raw material for the production of GRC board is cement and glass fiber. Due to the high tensile strength and elastic modulus of glass fiber, adding a small amount of glass fiber in the cement matrix material can greatly improve the low tensile strength and brittleness of the cement-based material Shortcomings, access to bending strength, tensile strength, high impact strength of the composite material. However, the glass fiber is susceptible to the erosion of the liquid hydration product of the cement hydration product and weaken its effect on the cement matrix material. In order to improve the durability of the GRC material, it is necessary to use low basicity cement or modified cement and alkali resistant glass fiber. Europe and the United States more use of modified Portland cement and alkali-resistant glass fiber to match, China's low alkalinity sulphoaluminate cement and alkali-resistant glass fiber to match.
