Not JUST a grout no.
You can get a cement that will also work as a grout but a pure grout would not have the adhesion required to stick the tiles to the wall properly, you should not use it as a cement.
The obvious answer is sanded grout has sand. But the in depth answer has many differences. Sanded grout which is the most common, can be used in a grout joint from 1/8" to 1/2" (and larger but check the grout). Sanded grout scratches many tile like glass. Non sanded grout can only be used on joints 1/8" or less. Non sanded grout is typically seen on marble and granite tile, many wall tile, and all glass tile.

it could be a number of things, premixed thinset, to much flex in the substrate, mixed thinset too thin, didnt seal grout "if in shower" where is the tile installed, what did you use to install it and how did you install it?
Grout is not toxic. Grout sealers and adhesives can be toxic but not the grout itself. Tami Barker www.mosaicforms.com Mosaic Art Instructor and Creator
Yes, you can change the color of the grout. There are products that you can use to try to die the grout or you can just have your tile re-grouted.
Porcelain is usually sealed already. You then add sealer to the grout.

The sealant goes on the grout not on the tile & yes it is a great idea & do it quickly before the grout starts to get stained by use.
Porcelain tile is basicaly glass & doesnt need to be sealed, sounds like some sales person is trying to sell you a smoke grinder. The grout should be sealed but your wasting your money sealing a porcelain tile. Ceramic, maybe, saltillo absolutely, but not the porcelain.
