Use of sea sand as fine aggregate in concrete making

2021-11-22  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.

The obtained results show that the crushed seashells (0/5 mm class), can be used as the fine aggregate for self-compacting mortar, without affecting the essential properties of mortar. However, the flowability of mortars based 100% of seashells, was better and is suitable for a fluid concrete (as a self-compacting concrete).
