what is the effect of salt water in cement mortar lining

2006-8-14 Salt water contains salt which have a low compressive strength. If a signicant amount of salt is mixed with concrete, the mixture's compressive strength will be lower than when you use tap water. Sooner or later these salts will melt and would cause pores or small holes in your cement. This will also decrease strength.
