Glass fibre reinforced concrete (GFRC/GRC) comprises hydration products of cement, or cement plus sand, and the glass fibers. Glass fibers are used as reinforcement for concrete. Properties of Glass Fibre Reinforced Concrete

Addition of glass fibres of about 10% by volume increased the tensile strength by roughly two times, and the impact resistance by about 10 times. The cyclic loading tests conducted on glass fiber cement laminates showed fatigue resistance of Glass fibre reinforced concrete (GFRC/GRC) roughly comparable with that of Steel fiber reinforced concrete (SFRC).

Composition

1. Cement: Generally Portland cement is used.
2. Aggregates: Fine aggregates are used in general in the making of GFRC/GRC
3. Glass fibres: Continuous filament and alkali resistant fibres are preferred
4. Polymers: Acrylic polymers are preferred

GLASS REINFORCED GYPSUM (GRG)

The use of glass fiber reinforcement has many advantages because the glass strands span the full width of the elements, and liquid plaster expands slightly on setting, the stands are pulled into tension by the plaster resulting in a naturally pre-stressed structure.

 

In addition to that, GRG elements are unaffected by humidity levels upto 95% R.H. they are non-combustible and will not support the growth of bacteria and other microorganism.

 

Finally, we specialize in drawing inspiration from the wonderful world of gypsum and experience the joy of seeing things in a whole new perspective. A traditional of quality where every curve detail represents a passion, and the love to create something special.

 

Gypsum contains a wealth of exciting possibilities and only human imagination sets limits to its use .gypsum has always been, and always will be proof that mankind is able to utilize one of nature’s own products to create inspiration and impressive interiors.
