Xtra Strength: Cement strength is measured in Megapascals (MPA) – which the cement achieves in 28 days of setting time. The 42.5 cement from Dangote achieves 42.5 MPA strength in 28 days’ setting time.
Xtra Life: 42.5 is ground finer than 32.5, which gives a finer finish to the concrete work. Additionally, the mixed cement has fewer air-pockets and therefore adheres better and has a longer life.
Xtra Yield: Also, because of its higher strength characteristics, 42.5 grade cement gives higher yield (about 8% more) than 32.5,
