Answer Posted / sandip
the water cement ratio of m-20( 1 : 1 1/2 : 3 ) is taken normally 0.45 . Example for 1 cmt m-20 grade of concrete cement consumption is around 350 kg, thus the water consumption will be as below
consumption of water = cement x 0.45
= 380 x 0.45
= 171.00 kg ( =188 lit )

How its coming concrete grade M 20 means 1:2:4. how it coming 1:2:4.
find the discharge of water through a horizental venturimeter having 400mm dia at the inlet main and 150mm dia at thorat.if the diffrential gauge between inlet and thorat shows a pressure head of 25cm mercury. assume coefficient discharge 0.98 and specfic gravity of mercury as 13.6.
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.
