Ans: M15 grade indicates the grade of concrete used in the structure i.e M indicates the design mix proporation and 15 indicates the compressive strength of conctrete at 28 days in N/mm2
1:2:4
15 milligrams
It depends who is doing the testing and what tests are carried out.
The grade of concrete for various concrete proportions areM10 - 1:3:6 (Cement:Fine aggregate:Coarse aggregate)M15 - 1:2:4M20 - 1:1.5:3M25 - 1:1:2
It depends on the Grade of Concrete. general grades are M15, M20, M25 etc. here are the nos. of bag required -------------------Bag for 1 cum---------------Bag for 5 cum M15------------------- 6.4----------------------------32 M20-------------------- 8-----------------------------40 M25--------------------12----------------------------60
Which M15 (be specific), if you are talking about the M14 variant i.e M14E2/M14A1; it is the same a a regular M14.
M 15 grade proportion - 1:2:4 (cement:FA:CA)Cement required in kgs - 325 kg per cu.mNo. of bags required - 6.50
1:2:4
Yes there is
For M10 (1:3:6) Grade of concrete cement bag consumed = 4.4 bags/cum M15(1:2:4) Grade of concrete cement bag consumed = 6.6 bag/cum M20(1:1.5:3) Grade of concrete cement bag consumed = 8.2 bag/cum
15
im guessing M15+ :)
