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. |
|
| |
"GRC Products are easy to
mould, handle and fix" |
|
| |
Premix GRC products are manufactured
by preparing a mixture of microconcrete with Alkali resistant
glassfibres in a special mixer and casting into moulds with
the aid of vibration. The properties of premix are different
to those of sprayed GRC. The advantages of vibration cast premix
GRC is speed and materials control. |
