For 1 m3 of concrete (1:2:4)
for Required volume of concrete 1.00
Add extra for additional voids in concrete ( 25% to 35%)
0.35
Total qty= 1.35 Cum
Mix total (1+2+4) 7

Therefore Quantity of cement = (1.35/7) 0.19
Cum
Qty of Cement in bags = ( 0.19/0.03) 6.4 Bags say(7
bag)
Qty of sand in bags = ( 0.19*2) 0.39 Cum
Qty of Aggregate = ( 0.19*4) 0.77 Cum

A doubly reinforced concrete beam is 25 cm wide and 50cm deep to the centre of tension reinforcement. The centre of compression is steel is 5cm from the compression edge. The areas of the compression and the tension steel are 10.16cm2 and 12.56 cm2 if m=18 and the bending moment at the section is 7,000,000 N-cm. Calculate the stress in concrete and steel.
