摘要
A concrete composition contains hydraulic cement, inerts, water and a superfluidifying additive obtained by salifying, in the form of an alkaline metal, alkaline earth metal or ammonium salt, the sulphonated and oxidised products resulting from the reaction between sulphur trioxide and fuel oil deriving from steam cracking. This concrete composition has improved workability characteristics and enables concretes to be obtained generally possessing greater strength and durability.
