1) compressive strength of concrete cube of size 150*150*150
for M20 is > 20n/mm^2 (should be above 20 and in no case <)
M30 is > 30n/mm^2

2) tensile strength of mild steel is 250 n/mm^2 (limit state)
and in working stress 150 n / mm^2

HYSD bars strength is 415 , 500 n/mm^2

HTS bars is 1200 n/mm^2 and for others hts tensile
strentgh is stress corresponding to 0.2 % of strain known
