What is Glassfibre Reinforced Concrete

Glassfibre Reinforced Concrete (GRC) is a high strength mixture of fine aggregates, cement, water, chemical admixtures and special Alkali resistant glassfibres. Like normal reinforced concretes, GRC can be engineered to suit the particular application.

"GRC is used to manufacture high strength, thin sectioned, prefabricated products".
High performance GRC enables manufactures to produce thin sectioned (as low as 6mm) low weight prefabricated architectural, building and engineering components.
How is GRC Products Manufactured ?.

Prefabricated lightweight glassfibres reinforced concrete products are manufactured worldwide. There are a various manufacturing methods, including:

Sprayed GRC: Sprayed GRC products are manufactured by projecting a high performance microconcrete simultaneously with Alkali resistant glassfibres using a special spray gun.

The advantage of spray is that it can be used to manufacture large components with surface areas of up to nearly 30m2.
