Project on Concrete Mix Design for various grades of Concrete

the mix calculation as per unit volume of concrete m35 grade with fly ash

a) volume of concrete 1m³

b)volume of cement 277/3.15*/1/1000=0.0879365079

c)volume of fly ash 118/2.2*1/1000=0.0536363636

d)volume of water 158/1*1/1000=0.158 m³

e)volume of chemical admixture 7.6/1.145*1/1000=0.0066375546

f)volume of all aggrigete

0.087+0.053+0.158+0.006=0.304-1= -0.696

g)mass coars aggrigete =f x volume of coars aggrigete x specific gravity of fine aggrigete *1000

0.696*0.431*2.74*1000=821.93424 kg m³

the mix calculation per unit volume of concrete m50 grade without fly ash

a)volume of concrete 1m³

b)volume of cement 359/3.15*1/1000=0.113968254 m³

c)volume of water 158/1*/1000=0.158 m³

d)volume of chemical admixture 7.6/1.145*1/1000=0.0066375546

e)volume of all aggrigete 0.114+0.158+0.006=0.722 m³

f)mass coars aggrigete 0.722*0.568*2.74*1000=1123.66304 kg m³

g)mass of fine aggrigete 0.722*0.431*2.64*1000=821.52048
