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.
Cement is hydrated limestone. Concrete is cement, stone and sand. Sometimes fiberglass fibers are added to increase strength.
The mineral component of cement are,Calcium oxide - CaOSilicondioxide - SiO2Aluminiumtrioxide - Al2O3Magnesiumoxide - MgOFerrousoxide - Fe2O3AlkaliesSulphur trioxide - SO3
No, cement won't rot.But cement losses its strength when it is not used for longer period.It is expected that there will be 50% of loss in strength when the cement is not used for more than 2 years.

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.
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.
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.
Functions of fly ash in cement,It is used as a replacement material.Low heat of hydrationGains strength more than that of the ordinary cement.
