Application Summary AI generated
GB/T 35161-2017 specifies the definition, technical requirements, test methods, inspection rules, and packaging for ultra-fine portland cement, which has a specific surface area greater than 600 m²/kg. It is applied in specialized construction projects requiring high early strength, low permeability, and superior durability, such as grouting in underground engineering, repair of concrete structures, and production of high-performance precast components. The standard ensures consistent quality for cement used in demanding environments like tunnels, bridges, and marine structures where fine particle size enhances penetration and bonding.
