Concrete strength classes 20/25 and class 25/30 can be produced with Portland-limestone cement grade 42.5 using 1:2:4 and 1:1.5:3 mix ratios respectively. Concrete mix ratios are the proportions of concrete components such as cement, sand, aggregates and water. M25 grade concrete ratio is 1:1:2 mixture of cement, fine aggregates and course aggregate in which one part is cement, one part is sand and two part is aggregate.
