ما نطاق كثافة مادة GRC؟ وما مزاياها مقارنة بالحجر الطبيعي؟

The density of GRC ranges from 1800-2200kg/m³ and can be adjusted through mix proportions according to application requirements. Compared with natural stone (density 2500-2800kg/m³), it is 30%-40% lighter at equivalent strength, and offers advantages such as strong design flexibility, convenient construction, and low overall cost.

In the Wuhan Hanxiu Theater project, GRC curtain wall panels had a density controlled at 1950kg/m³, 35% lighter than stone, significantly reducing structural loads. Through optimization of the rear steel frame, unitized installation of 4m×2m large panels was achieved, improving work efficiency by 3 times. More importantly, GRC can achieve complex curved surfaces that are difficult to process with stone; the double-curved panels in this project achieved a precision of ±2mm, which natural materials cannot match. In terms of whole-life-cycle cost, the 50-year maintenance cost of GRC is only 1/3 that of stone, and it involves no environmental issues from quarrying, truly realizing the concept of green building.

Lightweight Advantages

Weight reduction of 30%-40% lowers structural costs. Installation efficiency improved by 2-3 times. Transportation costs reduced by 25%. Foundation costs saved by 15%.

Designability Advantages

Any curved shape can be achieved. Panel sizes up to 5m×3m. Minimum thickness down to 10mm. Patterns and textures freely designed.

Construction Advantages

Dry construction keeps the site clean. Unitized installation shortens the construction period. High precision with tolerances ≤2mm. Winter construction is possible, unaffected by temperature.

Overall Economic Advantages

Initial cost lower than premium stone. Long maintenance cycles with low costs. Service life up to 50 years. No depletion of mineral resources.

GRC is an upgraded alternative to natural stone. Through technological innovation, Qinglong GRC continuously enhances its product competitiveness.
