Preparation of high performance non-dispersible concrete

Abstract

A new-type underwater non-dispersible concrete admixture NDA was prepared, its function mechanism was analyzed, and C40 high performance non-dispersible underwater concrete was manufactured by applying NDA. The results indicate that NDA has a suitable workability, low strength loss, and excellent anti-dispersion; the fresh non-dispersible underwater concrete with NDA has high anti-dispersion, excellent workability such as self-compacting and not bleeding; hardened non-dispersible underwater concrete with NDA has a high strength, high durability such as high anti — abrasion, impermeability and anticorrosion.
