Glass fiber reinforced concrete or GRC, is a type of fiber-reinforced concrete, are mainly used in exterior building façade panels and as architectural precast concrete.

GRC, consists of high-strength glass fiber embedded in a cementitious matrix. a combination of properties that cannot be achieved with either of the components acting alone. In general, fibers are the principal load-carrying members, while the surrounding matrix keeps them in the desired locations and orientation, acting as a load transfer medium between the fibers and protecting them from environmental damage.


The design of GRC panels proceeds from a knowledge of its basic properties under tensile, compressive, bending and shear forces, coupled with estimates of behavior under secondary loading effects such as creep, thermal response and moisture movement.

GRC products has the features of elasticity and tensile stress-strain characteristics, mechanisms of damage development and growth in the composite structure .Also provides mechanisms for high-energy absorption on a microscopic scale comparable to the yielding process. Other important characteristics of many fiber-reinforced composites are their non-corroding behavior, high damping capacity and low coefficients of thermal expansion.

GRC architectural panels have the general appearance of pre-cast concrete panels, but differ in several significant ways. For example, the GRC panels, on average, weigh substantially less than pre-cast concrete panels due to their reduced thickness. Their low weight decreases loads superimposed on the building’s structural components. The building frame becomes more economical.
