Compressive strength of the cement is the property of cement which specifies how much load it can withstand when cement is made into a hardened mass mixing with standard sand and water. The process of testing compressive strength of concrete and and cement may be somewhat same but the materials required for preparing cubes are different.

Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures. Compressive strength of concrete depends on many factors such as water-cement ratio, cement strength, quality of concrete material, quality control during the production of concrete, etc.

The strength of the mortar depends upon the fineness of cement, the gradation of sand and the most important factor which water-cement ratio. If any one of the above factors is not according to the ASTM-Standard then the strength of mortar is badly effected.

Mortar compressive strength is influenced by mortar water content at the time of set. Because molded mortar specimens are not in contact with absorptive masonry units and are not subjected to other mechanisms of water loss, they have a higher water content than mortar in the masonry. Higher water content results in lower compressive strength.
