Hello,
Our company is currently in the process of adding a new testing method to our lab. It is testing concrete for alkali silica reactivity. I have been informed of a couple different test that can acheive this. First is the uranyl acetate test which involves the use of uranium and UV lights. The use of uranium and UV light has lead many people to advise against the use of this test. The only other method I have come across is the use of a 10% copper sulphate solution which reacts with the silica gel in the concete to produce a colorful image. I really don't know a lot about this test and am wondering if anyone out there has more information on this or any other test method for alkali silica reacitivity. It will primarily need to be a field test so portability is important. Thanks.
