TDS for water in concrete? 2

[WWTEng]

Has anyone ever heard of TDS (total dissolved solids) for water that can be used for concrete mixture? This is the first time I heard of the term and I am not even sure if I heard it right. It could actually be TDC?

Forgive my ignorance. I alwayws thought water has to be potable but beyoned that never really looked into it.

Never have I heard of that. Potable water should meet any requirements though.

Yes, it is "total dissolved solids". When you get swimming pool water tested, that is one of the results.

See the PCA boook on the design of conrete mixes. They say that TDS under 2,000 ppm is usually ok for mixwater. There's also a discussion of the effects of various compounds on concrete. There are references to various tests that can be done to verify the suitability of water that may be of questionable quality.

Hokie, DB

Thank you. Is there anything about the max salt contents in the water used for conc?

Yes. If it's non potable, you need to meet ASTM C1602, which sets limits for salt, sulfates, chlorides, etc.
I guess they figure if it's drinkable, it meets those by default.
