Hi,

I have tested the bore water in my project for construction quality and it doesnt meet the required specification of Indian Standards (Table 1- Cl 5.4 in IS 456). I have 650 mg/l for chlorides and 860 mg/l for Organic solids.

But when I checked it with American Standards (ASTM C1620 Table 2_ I have attached it along with this post), it seems to meet the required specification.  Are Indian Standards are too conservative in water quality ?. Purchasing water from outside has some problem like cost of it will be higher during summer, we cant monitor the quality of it for each and each every tank etc,. Im not sure whether Im right about it, please correct if Im wrong.

Can I proceed with this bore water or should I need to purchase it from outside ?

Why I cant consider American standards ? Because our code books also take reference from other country standards.


With Regards

Ajith Karunanithi

Addition of neutralising chemicals commercially available may be tried, to bring in line with IS code.Good observation that US code is comparatively liberal.

Dear Er.Ajith

The Indian Codes are generally conservative in comparison with US and UK Codes

This is probably because the average quality of construction in India is lower than the more advanced countries

Also, I believe that there is a strong lobby of calcium chloride manufacturers in USA who are interested in maintaining the sales volume of calcium chloride in additives. India is one of the few countries who have banned chlorides in admixtures.

I prefer to follow Indian Standards

S.P.Srinivasan

Mr.Ajith,
The excess cholrides is not suitablefor RCC. We are facing a problem within five years for construction. Pl take care.
