Use of sea sand as fine aggregate in concrete making

2022-1-12  The main reasons why it is not acceptable for concrete making is the presence of sea shells and the chloride content. Raw Sea Sand. Fine Sea Shells in Coarse Fraction. Sea Sand After Washing. It has been argued that shell content has no adverse effect on the strength of concrete as such, but the workability is reduced.

Chloride Analysis of Sea Sand for Making Concrete ...

2016-5-6  Sea sand is not used in concrete, since it contains chloride ions which can corrode steel. In order to avoid the corrosion, the salt content of the sea sand must be eliminated before being utilized in concrete. Present paper investigates adopting sea sand as fine aggregate in concrete. The physical properties like specific gravity, percentage ...
