The sand acts the same as the rocks & gravel in concrete, they add strength, volume and keep the chalky grout product from crushing.
No sanded groud should be used on polished stone with very narrow groutlines, but sand must be added for wider grout joints or the product will lack volume, be chalky and crack.
there will not be enough strength
Grout is a substance that is used to fill gaps between tiles, such as in a shower or bathroom. Grout may be made of small aggregate, sand, and Portland cement. It may also be made of Portland cement or masonry cement and sand. There are many different types of cement, and these are usually used as an ingredient with which to make concrete and mortar.
Grout is little more than a mixture of sand and cement. To make grout, add just a little bit of sand to a bucket of cement. Mix it it a creamy paste. If you add too much sand, it will be too hard to stir.

The water ratio for mixing sand and grout varies depending on the specific type and brand of grout being used. Typically, it is recommended to follow the manufacturer's instructions on the packaging for the correct water-to-grout ratio to achieve the desired consistency for your project. It is important to mix the grout thoroughly to ensure proper hydration and strength of the final product.
The best type of sand to use for patio grout is polymeric sand. It is a mixture of fine sand and a binding agent that hardens when exposed to water, creating a strong and durable bond between the pavers. Polymeric sand helps prevent weed growth, erosion, and insect infestation, making it an ideal choice for patio grout.

Grout is a construction material used to embed rebars in masonry walls, connect sections of pre-cast concrete, fill voids, and seal joints (like those between tiles). Grout is generally composed of a mixture of water, cement, sand and sometimes fine gravel (if it is being used to fill the cores of cement blocks). Sometimes color tint is applied as a thick liquid and hardens over time, much like mortar.

Two answers here: Grout should be sanded to add strength, just like you add rocks & gravel to cement to make concrete stronger. Grout wears off a little every day & IF the flooring has a very shiny surface, polished anything is very soft, like sandstone, Travertine, Coral or marble The sand in the grout is much harder than the stone & the released bits of sand from the grout will actually scar & scratch & dull the shiny polished surface as the traffic grinds it into the floor. The installation of the wet, sanded grout can also start the delustering process. Very narrow joint up to about 1/4" are usually considered to be safe to do without sand, but over that, an aggregate is needed & sand is the ideal.
