Very informative discussion, engineer. I wish your different kinds of mixes also show the PSI strength of each mix. I am used to being told on PSI( pounds per square inch) required ,although PSI strengths are made thru correct water cement ratio.
2:20 That's a somewhat dated oversimplification. Modern concrete has all sorts of additives now, depending on the application ... including but not limited to things like fly ash (strength enhancer), fiberglass fibers, set inhibitors, tints, et al.
Thanks teacher for your explanations, but I have aquestion, 1) what is the difernece between M15 & C15 and their mix ratio? I confused basd on the ratio. I'm in Ethiopia, Africa, but mostly we are using C25 concrate and the ratio is 1:2:3, is corect teacher?
M standard signifies cube of sample size of concrete (cm*cm*cm) while C standard signifies cylindrical sample size of concrete, in short strength of cylindrical sample = 0.8* strength of cube sample ( 0.8*M25 is equal to C20) or C20 is equivalent to M25 gradings

Way they take characteristics strength of concrete after 28 day...way not 27 or 29 day... what's the reason?
Hardik Patel its the normal days for concrete to achieve maximum strength.
