Abstract
Purpose
The purpose of this paper is to focus on the durability of underwater non-dispersible concrete in seawater environment.
Design/methodology/approach
In this paper, ten groups of underwater non-dispersible concrete mixtures were designed, and the anti-dispersibility and fluidity of the mixtures were tested.
Findings
The durability test analysis shows that different pouring methods have different effects on the durability of concrete. The durability of concrete poured on land is better than that poured in water. Different mineral admixtures have different effects on the durability of concrete: the frost resistance of the underwater non-dispersible concrete specimens with silica fume is the best; the impermeability and chloride ion permeability of the non-dispersible underwater concrete specimens with waterproofing agent are the best; and the alternation of wetting and drying has adverse effects on the durability indexes of the non-dispersible underwater concrete.
Originality/value
The durability of underwater non-dispersible concrete is tested and the results can be used for reference in engineering practice.
