GRC
MGO
- Material: chopped glass fiber premixed with cement, 5% fiber content.
- Machine spraying process bring the body high-density molding.
- Glass fiber mixed with the cement with multi-directional traction make the body more stable and durable.
- Material: glass fiber layers with MgO, 2-3% fiber content.
- Hand-formed process, low density body and not strong enough.
- Layered MgO and glass fiber is uncompacted, single direction traction, body not tightly bonded.
Material Characteristics
- Concrete is a relatively stable material.
- 4-6 hours per molding, 2 molding per day.
- Molded body needs 28 days’ fully reacting and maintaining, then the strength reach 100% and no more future reaction.
- Natural concrete color available, high requirement of molding.
- 30-50% labour cost higher than MgO.
- MgO is a unstable material.
- 2-3 hours per molding, 3-4 molding per day.
- Molded body only need 7 days’ maintaining, MgO always react with water, so the surface needs to be covered by paint.
- Surface must be painted only, thus it’s easily repaired after molding.
- Easy process, less production time, lower cost.
