The world has a considerable seacoast area; many cities and towns and villages were established across the sea coast regions. Huge construction activates are taking place across the seacoast areas.

Due to use of groundwater in these regions many buildings are affected with corrosion. In order to get potable water for mixing and curing of concrete in these regions, people have to buy potable water and its increase cost for construction.

Hence, in this experimental work, an experimental investigation is disbursed on the removal of chlorides in groundwater by utilizing ordinary Portland cement square blocks. Cement square blocks, size of 50 x 50 x 10 mm, with water cement ratio 0.

28 were cast with ordinary Portland cement. Results discovered that cement square blocks were cast with ordinary Portland cement has given good expulsion of chlorides in groundwater samples.

And considerable impact on ions concentration that are a gift in groundwater. And regression analysis was carried out on experimental results.

Results from regression analysis and laboratory experiment are compared. Regression analysis is perfectly fit for experimental results and R square values of all characteristics.
