Quick setting cement & "53 grade of cement"-what does it indicate.

Quick setting cement:

This cement as the name indicates sets very early. The early setting property is brought out by reducing gypsum content at the time of clinker grinding. This cement is required to be mixed, placed and compacted very early. It is used mostly in underwater construction where pumping is involved. It is also used in typical grouting operations.

"53 grade of cement":

Grades 53 indicate the compressive strength of cement in Newton's for one mm² area.

i.e.,53 grade means a compressive strength of 53 N per mm² attained after a curing period of 28 days.
