Ordinary Portland Cement-Grade-43 is a high strength cement confirming of IS 8112:1989. The cement is ideally suitable for all kinds of normal constructions of buildings, commercial complexes and residential units. "

The finer the cement higher the grade number. It just indicates that the cement gains early strength. But the ultimate strength is same for all the grade of cements. The 53 grade gains the 28 day strength of 33 grade in seven days. But all cement and cement products gain strengthe with aging. For works where form work has to be removed quickly higher grade cement may be used. But curing is critical for higher grade cements; other wise they tend to develop surface cracks.
