Abstract:
Authors filtrated representative cement,liquid agent and high efficency nondispersible agent,adoptingnondispersible concrete mixture technology. Mixture construction performance choiceness underwater concrete was compounded. Based on Analyzing flowing, workability and physics mechanics capability,authors emphatically studied underwater concrete durability, adopting resistance seeping test,chlorin ion electricity flux test and chlorin ion pervasion coefficient test to appraise underwater concrete durability performance. The results show that underwater nondispersible concrete strengh, deformation capability satisfy requirement, chlorin ion electricity flux of underwater nondispersible concrete is less than 1000 coulomb, chlorin ion pervasion is less than 3.0×10-12 m2·s-1, durability capability is choice, the technique guide line is more than correlation Chinese code, and satisfies technique and engineering requirement.
