Concrete is composition of the sand -cement-crawl-water Mortar concrete is composition of the sand cement and water Cement is a powder which cause the water observed and hold the sand and crawl together .
so far no one has it exactly right...cement is the powder that binds mortar and cement together...mortar is cement , lime,, sand and water... concrete is cement, sand, gravel and water.. ncrete without gravel is refered to as cement also... edit_ dont just give me a thumb, prove me wrong...
mortar is sand, cement and water used for brick/block laying,Concrete is a mixture of sand, cement and aggregate( stone/pebbles)and water used for making a base, foundation, footing for a wall etc etc,cement is the stuff which when water is added has a chemical reaction causing the mix to go hard
Mortar and cement are basically the same except for different proportions of sand. Cement usually has less sand than mortar, which is why it looks smoother. Concrete is cement with lots of sand and some type of what they call aggregate; this could be gravel, metal pieces, ball bearings or anything else to expand the bonding surface area inside the mix. Also, concrete almost always have rebar in it except in very small applications. An interesting note: The acients Greeks and Romans used hollow clay pots as an aggregate. This caused it to have great strength at a fraction of the weight. Most of their greatest architectural/engineering feats using this method are still standing today and have become the basis of modern engineering, especially in domes where weight vs. support is crucial.
Mortar is used to lay blocks or brick together. It has no stone or gravel in it. Concrete is what sidewalks and floors are made of. It's composition is water, stone and sand (gravel) and cement. So you see, cement is what bonds these other products together to make concrete.
