Concrete is a well proportioned mixture of cement and other cementitious materials such as fly ash and slag cement, coarse aggregate made of crushed stone, fine aggregate such as sand, water, and chemical admixtures. The more inclusive answer is that concrete is a matrix of stone/sand aggregate adhered into a mass with a binding agent like Portland Cement or hot asphalt oil. This can refer to a person: He was as solid as concrete and would not move off his position.
Concrete is a composite construction material, composed of cement (commonly Portland cement) and other cementitious materials such as fly ash and slag cement, aggregate (generally a coarse aggregate made of gravel or crushed rocks such as limestone, or granite, plus a fine aggregate such as sand), water and chemical admixtures.

Why it is not suitable for all concrete mixture when the amount of fine aggregate and coarse aggregate is fixed?
There are two different types of aggregates namely,Fine aggregates - size of the aggregate is less than 4.75 mmExample : SandCoarse aggregates - Size of the aggregate is more than 4.75 mmExample : Gravel
Fine aggregates are the aggregates whose size is less than 4.75 mm.Example: Sand is used as fine aggregate in the preparation of concrete and cement mortar.
bulking of fine aggregate increases its volume. hence the mass for a given volume is less, which leads to richer mix than required. therefore batching of fine aggregate must be done by weight and not by volume.
Cement mortar is a mixture of cement, fine aggregate and water.Concrete is a mixture of cement, fine aggregate, coarse aggregate and water.Generally, concrete have higher strength than cement mortar.
