Mar 27 32 Grades Of Concrete In IS 456 the different grades of concrete are given as M10 M25 M20 M25 M30 M35 and M40 In the classification of concrete mix the letter M denotes the Mix and the numbers 10 15 20 25 30 35 40 represent the predetermined works cube strength of 15 cm cubes after curing of 28 days in N/mm2Concrete Technology Strength of Concrete Professor Kamran M Nemati Winter Quarter 1 Concrete Technology Strength of Concrete Concrete Technology 2 Strength of Concrete In concrete design and quality control strength is the property generally specified This is because compared to most other properties testing strength is relatively easy

Rebar is placed inside the forms and tied to any adjacent rebar that was previously installed The concrete is then poured or pumped in The height of each lift of concrete is typically only 5 10 ft 15 3 m and the length and width of each dam section to be poured as a unit is only about 50 ft 15 m IS 456 has designated the concrete mixes into a 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 N/mm2 The mixes of grades M10 M15 M20 and M25 correspond approximately to the mix proportions
