Answer / vijay kumar. I found three grades,33, 43 and 53. A quote: "In fact, all cements are one and the same but for minor changes in the characteristics. By and large grade 33 cement would meet the structural requirements of ordinary and small scale consumers. 43 grade cement may be utilised for precast concrete production besides the sleeper manufacturers and other building components ...
53 grade cement means that the compressive strength of the cement after 28 days is 53 N/mm 2 when tested as per Indian Standards under standard conditions. 53 grade cement has a fast setting time as compared to 43 grade cement.
Aug 30, 2010· Ordinary Portland Cement(OPC) is the most widely used cement in the world for producing concrete, mortar, stucco, and nonspecialty grouts. Ordinary Portland Cement has 3 grades based on its strength namely 33, 43 and 53 grade that indicates the compressive strength obtained after 28 days of setting.

Even though only Ordinary Portland Cement is graded according to strength, the other cements too have to gain a particular strength. 33, 43 and 53 grade in OPC indicates the compressive strength of cement after 28 days when tested as per IS: 40311988, eg, 33 Grade means that 28 days of compressive strength is not less than 33 N/mm2 (MPa).
There are various categories of cement used in building works for various purposes. Thus, it is important to understand the properties of each type of cement and their uses. There are commonly three types of cement used in general construction purposes Ordinary Portland Cement (43 Grade 53 Grade), Portland Pozzolana Cement and Portland Slag Cement. 43 G and 53 .
Apr 04, 2016· As we know that there are many types of cement in the market to suit every need. Some of them which are included in the revised IS : are as follows: •Ordinary Portland Cement 33, 43, 53 grade (OPC), 53S (Sleeper Cement) •Portland Pozzola...
Jan 04, 2014· By and large grade 33 cement would meet the structural requirements of ordinary and small scale consumers. 43 grade cement may be utilised for precast concrete production besides the sleeper manufacturers and other building components producers, 53 grade., cement .
For 53 Grade OPC Cement, the minimum compressive strength achieved by the cement at the end of the 28th day shouldn''t be less than 53MPa or 530 kg/sqcm. Interesting Fact OPC 53 Grade and OPC 43 Grade Cement are similar in chemical composition but different in the grinding process.
Ordinary Portland cement is grey in colour and OPC is most available cement on the cement is classified into three grades based on their ability to achieve compressive strength at its 28th day. Difference between 33 Grade, 43 Grade and 53 Grade cement. 1. 33 Grade OPC cement
According to Portland Cement, Ordinary Portland Cement (GB), the national standard, the strength grades of ordinary cement can be divided into:, R,, R,, R, and their ages should be no less than the numerical value in Table initial setting time of ordinary cement .
Mar 06, 2020· No matter whats the brand of cement is, There are three different grades of Ordinary Portland cement which are available in the market. 33 Grade 43 Grade 53 Grade; 33 Grade of Cement: As per Indian Standards, IS 269 – 2015, 33 Grade of cement means the Compressive Strength of cement after 28 days is 33N/mm 2.
Oct 15, 2017· GRADE33; GRADE43; GRADE53; GRADE 33: The grade 33 Portland cement shows their high workability as compared to the other grades. In mortar for plaster and for masonry, the grade 33 was commonly used. Fineness = 300 kg/m^2. Crushing strength 3 days later = 16 N/mm^2. After 7 days later strength = 22 N/mm^2. After 28 days later strength = 33 N/mm^2
IS Code – IS 8112: 1989 for 43 Grade Ordinary Portland Cement.. 3. OPC 53 Grade Cement. OPC 53 is used when we need higher strength concrete at very economical cement content. In concrete mix design, for concrete M20 and above we can achieve 8 to 10% saving in cement with the use of OPC 53.
Nov 19, 2017· Hi every one !! These are the grades of ordinary portland cement. 53 43 and 33 is the mean compressive strength of cement mortar paste. When cement is mixed with sand in 1:3 ratio and placed in cubes of size mm then after 28 days under 90 % r...
Ordinary Portland cement has 3 grades that are 33grade, 43grade, 53grade. As per the Bureau of Indian Standard, these grades are differentiated by their compressive strengths and these strengths are expressed in megapascal (Mpa) that is N/mm 2. Compressive strength is a ratio of load per unit area. The load is calculated in newton (N) and the area is calculated in mm 2.
Physical and Chemical Properties of Ordinary Portland Cement (OPC) of different grades: Type of Cement 33 Grade (IS: ) 43 Grade (IS:) 53 Grade (IS: ) Physical Properties Minimum Compressive Strength, N/mm2 3 day 16 23 27 7 day 22 33 37 28 day 33 43 53 .
Jun 04, 2019· OPC cement is also known as "Ordinary Portland Cement". OPC cement comes in 3 grades, they are 33, 43, 53 grade cement. But why it is known as Portland Cement? It is just because this cement .
Sep 07, 2018· 53 grade cement means that the compressive strength of the cement after 28 days is 53 N/mm 2 when tested as per Indian Standards under standard conditions. 53 grade cement has a fast setting time as compared to 43 grade cement.
Even though only Ordinary Portland Cement is graded according to strength, the other cements too have to gain a particular strength. 33, 43 and 53 grade in OPC indicates the compressive strength of cement after 28 days when tested as per IS: 40311988, eg, 33 Grade means that 28 days of compressive strength is not less than 33 .
Mar 06, 2020· No matter whats the brand of cement is, There are three different grades of Ordinary Portland cement which are available in the market. 33 Grade 43 Grade 53 Grade; 33 Grade of Cement: As per Indian Standards, IS 269 – 2015, 33 Grade of cement means the Compressive Strength of cement .
The strength of 53 grade cement does not increase much after 28th day because of early gain while 33 grade cement continues to gain strength after 28th day. In addition, due to faster hydration process, the concrete releases heat of hydration at much faster rate initially and release of heat is the highest in case of 53 grades.
