Use of seasand and seawater in concrete construction

Use of sea-sand and seawater in concrete construction ...

2017-11-30  The need to desalt sea-sand before use in concrete leads to extra construction costs, and in addition for certain construction projects, freshwater is in short supply. Given this background, the possibility of directly using sea-sand without desalting and/or seawater in concrete has been explored,.
