Glass Fiber Reinforced Concrete (GFRC)

GFRC is a cement-based composite, reinforced with glass fiber. Fibers are usually used in concrete to control plastic shrinkage cracking and drying shrinkage cracking. They also lower the permeability of concrete and thus reduce bleeding of water.


GFRC GFRC Columns

Glass Fiber Reinforced Concrete is similar to concrete in its characteristics, but it is 80% lighter. GFRC is finished in a wide selection of colors and textures, eliminating finishing costs and reducing the maintenance cost since there is no need for painting.

Mainly for exterior use, GFRC is ideal for building facade panels, domes, columns and other architectural details traditionally made from precast concrete. GFRC is easily molded into desired shapes with clean lines and sharp details.

Some types of fibers produce greater impact, abrasion and shatter resistance in concrete. Generally fibers do not increase the flexural strength of concrete, so it can not replace moment resisting or structural steel reinforcement. Some fibers reduce the strength of concrete.

Early conventional borosilicate glass caused reduction in concrete strength due to alkali reactivity with the cement paste. Alkali resistant glass fibers (AR glass) were then produced resulting in long term durability, but other strength loss trends were observed. Better durability result was observed when AR glass is used with newly developed low alkaline cement.
