Answer / patel anita
M-Refers to mix of aggregate,sand,cement..& 20 refers to
compressive strength gained by concrete in 28 days by
casting cube of 15 cm.
fe-is symbol used for iron.
fe415-refers High Yeild Steel bars of Yeild strength(
tensile strength) equal to 415MPa.

Answer / shunmugapriya
M20-compressive strenth of concrete,
fe415-tensile srenth of steel

Answer / emdadul haque
(1) In the designation of concrete mix M refers mix
Proportion. like mix of M20 is(1:1.5:3)
The number(20) to the specified characteristic
compressive strength of 150mm cube at 28 days in N/mm^2.
(2) Fe is the chemical symbol for the element IRON, the
major component of steel.
415= characteristic strength of steel.

Answer / thiyagan
M20-M means mix proposition and 20 means compressive
strength of concrete at 28 days.
fe415-fe means yield strength of steel 415N/mm2

Answer / mogulaiah
m :- stands mix of concrete.
20 :- stands compressive stregnth of concrete in N/SQ-MM
attains of 15cm X 15cm X 15cm cube after 28 days curing
provided.
Fe415 :- stands tensoile strength of rebar N/SQ-MM
| Is This Answer Correct ? | 1 Yes | 0 No |
Answer / vishal s rao
M means mix and 20 means the characteristic strength of the concrete cube attained after 28 days of curing.
Fe is the chemical name for Iron and 415 is high yield tensile strength of the bar.

Answer / manish
like m20...where m refers to the ""mix"" which is the
proportion of cement:fine agg:coarse agg and 20 is d
compressive strength of d concrete expressed in N/mm^2.
like mix of m20 is 1:3:6 i.e 1 part of cement,3part of FA
and 5 parts of CA
