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
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.
