Abstract
Purpose
The purpose of this paper is to research the hardened properties of non-dispersible concrete in seawater environment, especially in seawater environment.
Design/methodology/approach
The main approach is according to the experiment.
Findings
The findings of this paper are: first, because of the washing effect of water, the strength of underwater non-dispersible concrete is lower than that of terrestrial concrete. Second, the strength of non-dispersible underwater concrete with silica fume increases remarkably at different ages. Third, underwater non-dispersible concrete does not produce new products when it is formed and cured in seawater.
Originality/value
In this paper, underwater non-dispersible concrete is formed and maintained on land, freshwater and seawater by underwater pouring method. The working performance, mechanical properties and durability of underwater non-dispersible concrete mixtures after hardening are tested.
