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 grade in cement mainly defile the average compressive strength after 28 days in mega pascals (Mpa) of at least three mortar cubes (area of face 50 cm squared) composed of one part cement, 3 parts of standard s and (conforming to IS 650:1966) by mass and P/4 (P is the percentage of water required to produce a paste of standard consistency as per IS standard) + 3 percentage (of combined mass of cement plus sand) of water, prepared, stored and tested in the manner described in methods of physical test for hydraulic cement. 721 hr not < 23 MPa for 43 grade, 27 MPa for 53 grade 1682 hrs not <33MPa for 43 grade, 37MPa for 53 grade 6724 hrs not <43MPa for 43 grade, 53 MPa for 53 grade
PPC (Portland Pozzolana Cement) is typically classified as a grade 33, 43, or 53 cement, depending on its compressive strength. The numbers indicate the minimum compressive strength of the cement in megapascals (MPa) after 28 days of curing. PPC is known for its durability, resistance to chemical attacks, and lower heat of hydration, making it suitable for various construction applications.
For concrete roofing, Grade 43 or Grade 53 cement is typically recommended due to their high strength and durability. Grade 53 cement, in particular, offers superior compressive strength, making it ideal for structures that require enhanced load-bearing capabilities. Additionally, using cement with low permeability can help improve the roofing's resistance to moisture and weathering. Overall, the choice between these grades may depend on specific structural requirements and local building codes.
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.

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.

The specific gravity of Ordinary Portland Cement (OPC) - 43 grade typically ranges from 3.10 to 3.15. This value indicates the density of the cement relative to the density of water, providing insight into its composition and quality. Specific gravity can vary slightly based on the manufacturing process and the raw materials used.
43 grade OPC Cement it denotes the compressive strength of concrete in 43 Mega pascals will attain in 28 days. it is normally used for pavements, Non RCC structures and which are not important for initial strength. where as 53 Grade OPC Cement it denotes the compressive strength of 53 Mega Pascals will attain in concrete with the 28days, and it is used for RCC strengths and which are important to gain initial strength.
