GRC and GRG Core Performance Difference Analysis | Qinglong Material Property Comparison Study

GRC (Glass Fiber Reinforced Cement) and GRG (Glass Fiber Reinforced Gypsum) differ significantly in material properties, application fields, and construction techniques. GRC has a compressive strength of 40-60MPa and a flexural strength of 15-25MPa, and is mainly used for exterior walls and structural components; GRG has a compressive strength of 20-30MPa and a flexural strength of 8-15MPa, and is suitable for interior decoration. GRC offers excellent durability and is suitable for outdoor use; GRG allows fine, detailed styling and is suitable for complex interior decoration.

Performance comparison: GRC density is 1900-2200kg/m³, GRG 1500-1800kg/m³; GRC fire resistance limit is ≥2h, GRG ≥1h; GRC has good water resistance, while GRG can be used in high-humidity environments after moisture-proof treatment. One project selected GRC for its exterior walls and GRG for interior decoration, fully leveraging the advantages of each. Qinglong's scientific material selection delivers the best results.
