Know MoreConcrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregat For eg, a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse aggregate

Know MoreIt is the grade of concrete which indicates the strength of concrete after 28 days curing M #) means the strength of concrete after 28 days of curing will be 30 N/mm2

Know MoreConcrete Mix design calculation of M20, M25, M30 grade of concrete with example Concrete mix design is required to achieve target strength in structur Concrete Mix design calculation of M20, M25, M30 grade of concrete with example , As mentioned earlier to adjust fresh concrete properties the water cement ratio will not be changed Hence .

Know Moreratio, with an adequate margin, th e concrete may then be specified as a prescribed concrete using the sources and proportions of constituent materials used in the approved trial mix

Know MoreIn this project, general procedure has been given for the concrete of grades very from this procedure of M40grade of concrete the different grades such as M40 to M40 has been obtained by changing the values as per Indian standard 10dis so it is much easier to design the mix ratio for grade of concrete ,

Know MoreFollowing is a simple method used by engineers to calculate cement, sand and aggregate to produce different grade of concrete like M5, M75, M10, M15 and M20 if you don’t want to learn the math involved in the design, you can use the table given at the end of the article to produce different grade of concrete
