Mix Design of Concrete:IS Example and British (DOE) Method

[@islam56898]

29:19 start of DOE British method

[@gautamsandesh6076]

Thanks NPTEL team and sir.

[@girirajpaudel7310]

compressive strength for opc uncrushed is 42 and for crushed is 49 at 0.5 w/c

[@Lifefullofwonders22]

Sir why to calculate the target mean strength when u consider only exposure condition to calculate water to cement ratio...please explain.

[@UdayKumar-ox3hq]

Sir why only we increase 3 percentage in water content in Is 456 we see increase per 25 percentage increase 3 percentage so for 80 mm slump we should increase 6 percentage

[@flutofanta9480]

how did u get the fine % of aggregate from 0.45 w/c level? I dont get that point how do u get 30%? explain with clear stand plz !

[@azeemask4921]

What is 1.03 in calculating water content

[@ankitchauhan3207]

Extra 3 % for 80mm slump

[@hdevine922]

whats does DOE stand for?

Great

[@catherinegideon4689]

Your videos a good but sir they are too long

love for carry #carryminati

[@siphemnyandu6741]

This guy is confused. What an incredibly incorrect way to do a DOE method!

[@maheshmahatekar2885]

It is a shame that a Dr. Of Civil Engineering is himself so confused ! Lack of doing mix designs by hand is the only reason. Practical experience zero. Sorry state of affairs in Indian IIT's

[@akashmadale2674]

If using fly ash 25% ok Next u multiply by 1.1 with cement what is this (1.1) factor sir anybody know please answer sir

[@deeprajchaudhury9316]

So you think you know better mix design then Dr? Bro mix design is nothing, if u have codes, then it is sufficient to calculate this amount easily, nothing special.
