The basic principle which is generally used for mix design for proportioning mixes is abrams law for strength development. according to this law, for any given conditions of test the strength of workable concrete mix is dependant only on the water-cement ratio. lesser the water-cement ratio in a workable mix greater will be its strength.
Number of grades as m10, m15, m20, m25, m30, m35 and m40. in this designation the letter m refers to the mix and the number to the specified 28 day cube strength of mix in nmm2. the mixes of grades m10, m15, m20 and m25 correspond approximately to the mix proportions 136, 124, 11.53 and 112 respectively.
