Concrete mix ratio for beams. As we know that Beam is RCC structure so we can use minimum grade of M20 grade and concrete mix ratio 1:1.5:3 for beams & maximum grade of concrete m25, M30 and much higher are used as per design for beam. 1:1.5:3 (m20) is concrete mix ratio used for beam. Concrete mix ratio for Foundation.
