Strengthening Concrete
Silos with CFRP
Cracked, corrosion-damaged concrete silos were restored to full capacity using carbon fiber reinforcement, providing a durable and corrosion-resistant strengthening solution.
View PDFThe Problem
A consulting engineer in Cupertino needed to strengthen three 70 year old concrete silos that had developed significant cracking and deterioration. The silos stored mined materials containing corrosive elements, which caused the concrete to break down over time.
As the cracks worsened, the silos became structurally unstable, began leaking, and could only operate at 50 to 60 percent capacity, creating both safety and efficiency concerns.
⚠ Corrosion and cracking had weakened the silos, reducing their capacity and requiring a durable, corrosion resistant strengthening solution.
The Solution
The engineer selected Carbon Fiber Reinforced Polymer CFRP due to its high strength, corrosion resistance, and ease of installation. The concrete surface was prepared by cleaning and roughening it to ensure proper bonding.
Crews then applied 560 GSM bidirectional Rhino Carbon Fiber CFRP in 24 inch widths using a hoop wrapping method around the silos to provide reinforcement. A UV resistant coating was applied afterward to protect the material. This solution successfully restored the silos to full capacity and stable operation.
