Question

1.Find the pressures coming on the sides and bottom of a beam formwork for given below normal weight concrete.

Live load = 4.5 KN/m2

Beam size = 60x200cm

R= 5.0m/hr

Slump = 10cm

Concrete temperature = 20o C.

Formwork weight = 0.6kPa

2. If in one hour 30m3 concrete is delivered to a concreting    

   site to place the concrete into a wall formwork of 60m

   length and 0.6m width, what is the value of R?
