You betcha! You CAN go to some ot the coral sellers and buy their "special Coral frag glue" which is just gel-type of super glue in a fancy wrapper.
Like Edge says, Home Depot or wherever will have the stuff you need. It is strange to see it used so much nowdays. When I was in the hobby nearly 20 years ago, the attitude was "Cyanoacrylate? made from cyanide...poisonous to your tank. Don't use it!" Now, it's used for frags and repairs all the time.
OOps Sunny, you posted while I was typing...I don't think that mixing sand with the watery stuff will accomplish much. Just go get the gel, and you'll have much better luck.
