actually nominal mix is done on the basis of volumetric batching which is more costly for higher grades. concrete mix design m-25 - rcc. a-1):- design stipulation :-. (a). grade of concrete = m25. (b).characteristic compressive strength of concrete at 28 days = 25 n/mm2. (c). maximum size of aggregate = 20mm anguler. (d)..how to calculate rate analysis of m10 grade concrete,in nominal mix ratio of different material are already defined while in the design mix ratio is defined after the testing with different trial mixes. grade of concrete are such as as m10, m15, m20, m25, m30, m35 and m40 e.t.c. in this designation the letter m refers to the mix and the number to the specified 28 day cube strength of mix in n/mm2..mix design m25,mix design m25 1. q.no. design a concrete for strength m25 (i.e.25 .determination of appropriate mix ratios for concrete,from table 1, for all the concrete grades/strength classes, the cylinder strengths are higher than the cube strengths. for example, the concrete grade/strength class c20/25 concrete is expected to have a minimum cylinder crushing strength of 20mpa and the same c20/25 concrete is expected to have a minimum cube crushing strength of 25mpa. concrete
