take an example 1:4, total ratio(1+4)is 5. assume total
volume of mortar required is 10cubic metre. this will
contain 1/5of10=2cubic metre of cement and 4/5of10=8cubic
metres of sand. density of cement as 1440kg/m3, mass of
cement will be 2x1440=2880kg and number of bags
(i) 50kg is mass of 1 bag of cement.
(ii)other irregularities like covering voids, reduction in
volume/shrinkage due to setting of cement etc should be
considered by factoring the total volume by say 1.4.
(iii)for water use about 30% of the raw volume of sand and

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
