· Glass fiber reinforced concrete (GFRC) is well known for its high compressive strength-to-weight ratio. This benefit results from the high cement mixture and low water content. Other benefits are its high flexural strength (bending strength) and high tensile strength. GFRC also has appreciable load-bearing qualities.
