52.5 N refers to normal set time and 52.5 R is a rapid set time.
in a simple way it is the strength of concrete, which it can bear the loads of its specified grade ex C 25 grade can resist the weight of 25kn/m2 after 28days of 60% after 7 days.
Which Grade?
cement consumption in M-25
Cement grade M35 refers to the compressive strength gained at 28 days.Strength for M35 grade - 35 N/mm2 at 28 days.M35 grade is used in construction of bridges, tall structures,et.c
The specific gravity of Ordinary Portland Cement (OPC) 43 grade can vary slightly depending on the manufacturer and specific composition. However, as a general guideline, the specific gravity of OPC-43 grade cement typically ranges from 3.10 to 3.15. Specific gravity is a measure of the density of a substance compared to the density of water. It indicates how heavy a material is relative to an equal volume of water. OPC-43 grade cement generally has a higher specific gravity compared to water, which has a specific gravity of 1.0. It's important to note that specific gravity values can differ slightly based on factors such as cement composition, fineness, and variations in manufacturing processes. For precise information regarding the specific gravity of a particular brand or batch of OPC-43 grade cement, it is recommended to refer to the manufacturer's specifications or contact the manufacturer directly.

The OPC was classified into three grades, namely 33 grade, 43 grade and53 grade depending upon the strength of the cement at 28 days when tested as per IS 4031-1988. If the 28 days strength is not less than 33N/mm2, it is called 33 grade cement, if thestrength is not less than 43N/mm2, it is called 43 grade cement, and if the strength is not lessthen 53 N/mm2, it is called 53 grade cement.
charecteristic strength of Cement. 53N/MM2 and so on
Yes. OPC 43 grade cement can be used to make M20 grade concrete.It can be used to make concrete up to M30 Grade.See related link.
Cement grade M35 refers to the compressive strength gained at 28 days.Strength for M35 grade - 35 N/mm2 at 28 days.M35 grade is used in construction of bridges, tall structures,et.c
