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.
Since there are many features of grout, this will depend on your question. There are epoxy grouts and latex modified grout. Epoxy grout is very stain resistance. The problem lies in that epoxy grouts are hard for a novice to use. Latex modified thin-sets are durable when used correctly. Additionally, you need to make sure you buy sanded or non sanded grout depending on the size of the grout joint and type of tile. If you have many natural stones, glass tile, or a tile with a great deal of shine, you will need a non sanded grout. Many bathrooms need this regardless, because their grout joint is 1/8" or less. All joints larger than 1/8" require sanded grout. This means you must be cautious before you begin, you place your joints correctly for the style tile you have.

It depends on the type of grout you used. Typical cement-based grouts cannot adhere to existing grout in lines of less than 1/8" deep, and it's advisable to remove all the grout and do over. If your grout is an epoxy-based grout, or some varieties of pre-mixed grout, it might be possible. Check the label to see if it adheres to existing grout, and at what thickness.

Most often, sanded grout is used for floor tiles because the grout lines are usually greater than 1/8" wide. Sanded grout is necessary for the wider lines to give added strength, and to keep your grout from cracking and chipping out. Unsanded grout must be used if your grout lines are narrower than 1/8", because the grains of sand in sanded grout could cause air pockets and prevent good adhesion to your tiles - and it will crack and chip out as well. Sanded and unsanded grouts are cement-based. One alternative grout on the market is epoxy-based. It is neither sanded nor unsanded, but will work fine in either narrow or wider grout lines. If your grout lines are wider than 1/2", or if you are using saltillo tiles, you must use saltillo grout. Other grouts will not handle this wider width.
To fill an 8" x 8" x 16" concrete block with grout, you first need to calculate the volume of the block. The volume is 8 inches (width) x 8 inches (height) x 16 inches (length) = 1024 cubic inches. Since there are 1728 cubic inches in a cubic foot, this converts to about 0.59 cubic feet of grout needed to fill one block. Always consider purchasing a little extra grout to account for spillage or variations in the mix.
