As per thumb rule cement required per 1 cum of M20 concrete is 411Kg/cum(1.57/5.5=0.285cum of cement i.e 0.285*1440=411Kg).But as per PWD rate analysis cement required is 347Kg/cum.the difference is 64Kg.This kind of difference is coming every grade of concrete.Can you give perfect suggestion regarding this.

Design a cantilever slab to carry a live load of 2000 N/m2. The overhang of the slab is 1.20m. b) A slab over a room is 4.75m x 4.75m. The edges of the slab are simply supported and the corners are not held down. The live load an the slab is 300 Kg/m2. The slab has a bearing of 15cm. On the supporting walls. Design the slab as per Rankine - Grashoff theory. Assume weight of R.C.C. = 2400 Kg/m2.

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.

Design a reinforced concrete combined footing (rectangular) for two columns located 3.60 metres apart. The overall sizes of the columns are 40cm x 40cm and 69cm x 60cm and the loads on them are 1000 kn and 1500 kn respectively. The space available for the width of the footing is restricted to 180cm. The S.B.C. of the soil is 280 kn/mm2 use M15 concrete.

Design a cantilever type retaining wall to retain sand for 4m above the ground. The sand fall slopes at the rate of 1 vertical to 2 horizontal. The weight of sand is 18000 N/m3, the angle of repose being 30. The safe bearing capacity of the soil is 200 kn/m2 at 1/25m below the ground level. Use m 15 concrete mix.

1562

Design an underground tank of internal dimensions 6m x 3m x 3m. The soil surrounding the tank always remains dry. The tank shall be provided with a roof slab. The soil weighs 16000 N/m3 having an angle of repose of 30.
