ANSWER: The grade 43 and 53 in cement mainly corresponds to the average compressive strength attained after 28 days ( 6724 hours) 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.

What is difference between 43 and 53 grade opc cement?
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.

What is the difference between portland cement and pozzolan cement?
There are three kinds of cement PPC, OPC. SRC. Portland Pozzolana Cement (PPC) The Portland Pozzolana Cement is a kind of Blended Cement which is produced by either intergrinding of OPC clinker along with gypsum and pozzolanic materials in certain proportions or grinding the OPC clinker, gypsum and Pozzolanic materials separately and thoroughly blending them in certain proportions. Pozzolana is a natural or artificial material containing silica in a reactive form. It may be further discussed as siliceous or siliceous and aluminous material which in itself possesses little, or no cementitious properties but will in finely divided form and in the presence of moisture, chemically react with calcium hydroxide at ordinary temperature to form compounds possessing cementitious properties. It is essential that pozzolana be in a finely divided state as it is only then that silica can combine with calcium hydroxide (liberated by the hydrating Portland Cement) in the presence of water to form stable calcium silicates which have cementitious properties. The pozzolanic materials commonly used are: Volcanic ash Calcined clay Fly ash lica fumes OPC is environment friendly as well as economical Ordinary Portland Cement (OPC-53, OPC-43, OPC-33) OPC-43 GRADE The 43 grade OPC is the most popular general-purpose cement in the country today. The production of 43 grade OPC is nearly 50% of the total production of cement in the country. The 43 grade OPC can be used for following applications: General Civil Engineering construction work RCC works(preferably where grade of concrete is up to M-30) Pre-cast items such as blocks, tiles, pipes etc Asbestos products such as sheets and pipes Non-structural works such as plastering, flooring etc. The compressive strength of cement when tested as per IS code shall be minimum 43 MPa. The physical and chemical properties of this cement are given in the table: Physical Characteristics of 43 Grade OPC (BIS Requirement) Is Code Finene SS (sq.m/k g Min) Soundness by Setting Time Compressive Strength Lechatlier (mm)max Auto clave Max (%) Initial (mts) min Final (mts) Max 1 day Min Mpa 3 day Min Mpa 7 day Min Mpa 28 day Min Mpa (IS 8112- 1989) 225 10 0.8 30 600 Not specified 23 33 43 Chemical Characteristics of 43 Grade OPC (BIS Requirement) Is Code Lime Saturation Factor Alumina Ration Min Insoluble MgO (%) Sulphuric Anhydride Loss ignition (%) Max (IS 8112 - 1989) 0.66 Min 1.02 Max 0.66 3 6 2.5% Max when C3A is 5 or less. 3% Max when C3A is greater than 5 5 Sulphate Resisting Portland Cement (SRC) Sulphate Resisting Portland Cement is a type of Portland Cement in which the amount of tricalcium aluminate (C3A) is restricted to lower than 5 % and (2 C3A + C4AF) lower than 25%. The SRC can be used for structural concrete wherever OPC or PPC or Slag Cement is usable under normal conditions.
Is Portland Slag Cement 43 grade available in Indian market?
Yes..This is a slag-based blended cement that imparts strength and durability to all structures. It is manufactured by blending and inter-grinding OPC clinker and granulated slag in suitable proportions as per norms of consistent quality. PSC has many superior performance characteristics which give it certain extra advantages when compared to Ordinary Portland Cement It is available in specially designed 50-kg bags.
What is the difference between 43 and 53 grades of cement?
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.

What is the specific gravity of opc-43 grade cement?
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.
