Glassfibre Reinforce Concrete (GRC or sometimes GFRC) is a composite material comprising a mixture of hydraulic cement, silica sand, alkali resistant (AR) glass fibres and water. The glass fibres in GRC effectively reinforce the mortar mix thereby improving its tensile strength and characteristics.
The main advantage of GRC over the corresponding precast concrete alternatives is the considerable saving in weight. This results in savings in the costs of transportation, handling and erection. Other notable advantages of GRC cladding are its durability, seismic capabilities, chemical resistance, non-combustibility and good sound/heat insulation properties.
