This document discusses glass fiber reinforced concrete (GFRC), which is a composite material made of cement mortar reinforced with glass fibers. It explains that the addition of glass fibers improves several properties of concrete, including increasing tensile strength, reducing cracking from shrinkage, and improving durability. The key factors that affect GFRC properties are the relative amounts of fiber and matrix, fiber aspect ratio, fiber orientation, and workability of the concrete mixture. Different types of glass fibers include A-glass, C-glass, E-glass, and S-glass. GFRC has applications in exterior ornamentation, interior details, landscape furnishings, and infrastructure projects due to its strength, impact resistance, and durability.
