Precast Concrete Compared to GFRC
While precast concrete has been used longer compared to GFRC, which has been developed and used more commonly in the last few decades, there are some comparisons between the two materials that have led many construction and design firms to begin using GFRC more often than precast concrete. Here’s why:
The Differences between Precast Concrete and GFRC
Here is a chart that shows the differences between precast concrete and GFRC based on a number of factors:
| Factors | Precast Concrete | GFRC |
| Elasticity | Less elastic | More elastic |
| Density | Less dense | More dense |
| Impact Strength | Low impact strength | High impact strength |
| Permeability (Water and Air) | High permeability | Low permeability; virtually waterproof |
| Beauty | Some find beauty in concrete, especially those who like contemporary and minimalist architecture that uses concrete slab floors and countertops | Beyond the look of concrete, GFRC can also appear like natural stone, terra cotta, wood or smooth panels |
| Applications | It can be used in a number of applications but is limited when complex or highly detailed designs are required or its weight is too heavy | Higher number of applications, including being used as a true curtain wall exterior cladding and where panels need to provide structural support; can be used for highly detailed designs and complex architectural projects |
| Durability | Moderately durable; prone to cracks and seismic activity; it can become brittle; tends to chip when cut | Highly durable; less likely to crack; resistant to seismic activity and inclement weather; it has high tensile strength and the ability to lengthen when stretched |
| Diversity | Low diversity | Numerous colors, finishes, and textures available as well as structural shapes that can be made |
| Flammability | Does not burn | Does not burn; protects the materials behind it from heat from flame |
| Environmental-Friendly | Higher impact on the environment | Low impact on the environment; uses recycled materials; can be recycled; lowers transportation impact on the environment; produces waste; uses fewer natural resources |
| Weight | Considerably heavy | Lightweight; easier to pick up so it can be used to speed construction time |
| Installation | Complex; time-intensive; based on weather conditions | Simple; fast; can be installed in any weather conditions |
| Cost | Moderate | Highly economical based on all the aspects of the construction process where money can be saved |
