Water used for mixing and curing shall be clean and free from injurious amounts of oils, acids, alkalis, salts, sugar, organic materials or other substances that may be deleterious to concrete or steel.

The Water used for the construction activity should be free from acids, and the pH below 7 indicates presence of acids in the water, Thus, it won't be fitful for the construction activity.
Basically the pH value should be maintained nearly by 7.
Basically the pH value should be maintained nearly by 7.

Because the water which pH value is less 7is basis water more or equal its a acidic or presence of alkali or organic matter and minerals so maintain the pH value nearly equal to 7 for construction economy.

Acidic and basic content of water is harmful for the structure. So we can use water with ph value 7.

Yes water shall be free from bases and acids so ph = 7.

We can easily say that acidity of water organic matters is to known the under less than 7.

But IS 446:2000, Clause 5.4.2 (the pH value of water shall be not less then 6). So the correct answer is C.

But we use IS 456:2000 code book, (the pH value of water shall be not less than 6). So the answer is C.

Because beyond 6 (i.e <6) the water become acidic which deteriorates the cement or concrete.

Can anyone say the maximum permissible ph of water used for construction activity?
