We have used Filter sand for construction , Is there a problem in this sand?
I had to Google Trichy and filter sand to try to decipher your question.  

I'm guessing you mean you are using river sand from the Trichy area (Bangalore, India).  For structural concrete, you should have sand (about 1 mm), gravel (5 to 20 mm), and cement.  

If you have sand but no gravel, that is not good.  Gravel but no sand, also not good.

Some sand is dirty, with clay or organic material, and that is not good...but you say filter sand so that should be clean.  Some sand is too round/smooth to make a good bond and some, like crushed coral or pumice, is too soft.

In US we have very specific mix designs, test the sand and gravel, and we break samples of cured concrete to make sure it is as strong as advertised before removing formwork or shoring.

Good luck!
