Fuzzy comprehensive evaluation on the durability of subsea tunnel grouting materials

Long-term durability of grouting material of subsea tunnel is an important guarantee for the normal work.The main errosion factors of grouting materials include chemical errosions due to sea enviorment,physical errosions and effects of their own.Experiments are carried out on ordinary cement,sulfur aluminate cement,and superfine cement.Evaluation factors such as sulfate-resistant ability,water-resistant ability,chloride ion penetration-resistant ability and cubage stability are introduced,and th...
