Glass bre Reinforced Cement (GRC)
Glass bre Reinforced Cement ( GRC ) is a composite material consisting of a mortar of hydraulic cement and ne aggregate reinforced with alkali resistant glassfibre. The GRC may contain additional filler materials, pozzolanic materials and admixtures. The fibre contents are typically 3% to 5% by weight defending on product application and production method employed. The properties of GRC depend on a wide range of variables. These include the method of manufacturing, mix formulation, bre product type, length and orientation, add mixtures used etc. A GRC material may therefore be tailored to meet the particular requirements of a specific application. GRC Materials have a aggregate-cement ratio of up to 1:1, incorporating glass bre and made by spray and premix processes. These materials have been widely used for many years and their properties and characteristic have been studied extensively.
1. Lightweight, reduces transport and installation costs
2. Excellent Edge and Corner Strength
3. Improved Surface Details and Quality of Finish
4. Easy to mould into complex shapes.
5. Maintenance Free: GRC is an inert material, unaffected by salt, freeze/thaw cycles, or corrosive atmosphere. Unlike concrete, as it has no steel components, it is not weakened or cracked by steel corrosion and can live without mainte- nance for many years.
6. Ideal for Restoration Works: All the above characteris- tics point to GRC as the ideal material for restoration of old buildings, facades and decorative features, as GRC can replicate exactly, or improve upon, any original feature.
7. Environment friendly: GRC neither uses nor emits any volatile material, and is a low energy product, therefore contributes to a safe and clean environment.
