Good question! I had to pull some books off my shelf because this one peaked my curiosity.
There is a fair amount of ambiguity with these terms and I’ve heard them used interchangeably. All of the above responses seem right, but from an engineering perspective, I pulled this information from one of my books.
Mortar is used for the following functions: bonding masonry units together, serving as a seating material for the units, leveling and seating the units, and providing aesthetic quality of the structure.
Grout is used to fill the cores or voids in hollow masonry units for the purpose of: bonding the masonry units, bonding the reinforcing steel to the masonry, increasing the bearing area, increasing the fire resistance, and improving the overturning resistance by increasing the weight.
Using these definitions, grout uses fine gravel in addition to the sand both mixes use. The other ingredients seem similar with minor portioning differences.

Difference Between Mortar And Grout
2017-01-18 05:01:39 · answer #2 · answered by Anonymous · 0⤊ 0⤋
Grout is used to fill the spaces between tiles when you lay a tile floor. It can be used to fill hairline cracks in concrete for appearance sake, but is not be used in large cracks. It has very little holding power and is brittle meaning it will crumble easily. It is not meant to repair cracks in any sort of structural component. Mortar is used to join bricks or blocks together. If you are repairing cracks in mortar joints between blocks or bricks, then you could use mortar to do this, but it will be difficult unless it is a large crack. If it is a small crack, you will more than likely need to widen the crack or dig out some of the mortar in order to get good adhesion of the new mortar. Otherwise it will continue to fall out. Cement is used to create walkways and driveways, curbs, and walls. If you are repairing cracks in concrete (assuming it is a walkway, driveway, curb, etc) then you should use an appropriate concrete patch product. This comes in various sizes and is very easy to work with providing you dont add too much water and make soup. You could also use concrete mix but adding new concrete to existing concrete will probably cause the crack to reappear as there will not be any bonding between the old and new concrete. The concrete patch products have special ingredients that will create a bond to the existing concrete. Good Luck

Mortar is a material used in masonry to fill the gaps between blocks in construction.
Mortar is a mixture of sand, a binder such as cement or lime, and water and is applied as a paste which then sets hard. Mortar can also be used to fix, or point masonry when the original mortar has washed away
Grout is generally composed of a mixture of water, cement, sand and sometimes color tint which is applied as a thick liquid and hardens over time, much like mortar.

Mortar is used to adhere the tiles to the floor. A thin layer is spread across the floor with a specail groved trowel. Once the tiles are set and the mortar is dry, grout (which is basically sand, colored stone dust, and adhesive) is then spread inbetween all of the tiles with a rubber or foam trowel called a grout float.

The second guy is right. You set tile with thin set or mastik(glue) or if you do it the old school way you set it in dry pack with slurry. I have used mortar and/or grout to fill the gaps in stone work.

I'd give the 10 to Tucci. Any more of an explanation than that is uneccesary,,,no offense to others. He was the first to answer.
