Advantages and disadvantages of concrete pipes_
| Concrete pipes | |
|---|---|
| Advantages | Disadvantages |
| Adaptable to a wide range of loads, design pipes of any load capacity | High pipe weight making installation difficult |
| The possibility of practically any shaping of the cross-section | Short pipe sections which extend the assembly time |
| Large range of pipe diameters up to 3600 mm | No resistance to corrosive environments with pH less than 4. 0 |
| Higher wall roughness than other materials | |
Mechanical property of fibers (Sim et al_ 2005, Kizilkanat et al_ 2015, Karwowska et al_ 2011, Deng et al_ 2021a)_
| Basalt | Polypropylene | Steel | |
|---|---|---|---|
