Application of Repair Material and Technology for Concrete Damaged by High-speed Flow Scour
In view of the large-scale development and utilization of China's water resources,water conservancy projects have developed toward high heads,large flows,and high flow rates.Research has focused on high-speed flow scour,sand wear,and accompanying cavitation damage.The selection of materials sho...

| description | In view of the large-scale development and utilization of China's water resources,water conservancy projects have developed toward high heads,large flows,and high flow rates.Research has focused on high-speed flow scour,sand wear,and accompanying cavitation damage.The selection of materials shows that:①NE-Type II epoxy mortar has good abrasion resistance,mechanical properties,workability,carbonization resistance,aging resistance,and durability.②Polyurea coating has good abrasion resistance,environmental protection,strength,yellowing resistance,aging resistance,water resistance,stable performance,and low temperature flexibility to ensure smooth flow surface,which is a new type of environmental-protection waterproof protective elastic paint.③HF concrete has good workability,excellent crack resistance,low cost and mature technology.④The polyurethane sealant is easy to operate,fast in construction,bonded well with concrete,excellent in resilience,good in aging resistance,and free of flow at high temperature and brittle fracture at low temperature.NE-Type II epoxy mortar,HF concrete,polyurethane sealant are featured with strong resistance to high-speed flow scour,sand wear,and accompanying cavitation damage.Therefore,they are proper to select as repair material for high-speed flow scour,sand wear and damage. |
