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

	Basalt	Polypropylene	Steel
Tensile strength (MPa)	992.4 – 4800	706	550 – 1100
Elastic moduls (MPa)	95 000 – 115 000	7400	190 000 – 210 000
Corrosion resistance	+	+	−
Adhesion to concrete	Very good	Poor	Very good
Density (kg/m³)	1700 – 2750	950	7800
