mortar are mixing by sand & cement and concrete is mixing by cement, sand & stone
Require strength for Plaster?
That depends on the thickness of the cement, the strength of the cement, the age of it, Is it reinforced
Cement paste is formed when cement is mixed with water. However, cement mortar is formed when cement is mixed with fine aggregate (sand) and water.The strength of cement mortar is more when compared to cement paste.Shrinkage will be less in cement mortar and high in cement paste.
As concrete ages, its strength typically increases due to continued hydration of the cement particles, which can affect the water-cement ratio's impact on strength. Initially, a lower water-cement ratio leads to higher strength, but as concrete matures, the difference in strength between varying ratios diminishes. This means that while a low water-cement ratio is critical for achieving high early strength, the age of the concrete plays a significant role in enhancing overall durability and strength over time, regardless of the initial ratio. Thus, the strength curve generally shows a rising trend with age, independent of the initial water-cement ratio.

Due to prolonged storage of cement, it gradually loses its strength.
The compressive strength of 53 grade ordinary portland cement is 53 N/mm2 at 28 days.

charecteristic strength of Cement. 53N/MM2 and so on
Cement is hydrated limestone. Concrete is cement, stone and sand. Sometimes fiberglass fibers are added to increase strength.
