[4 marks]Give the characteristics of good quality Timber and Steel Formwork.
[7 marks]Write short notes on slip formwork.
[3 marks]What is lateral pressure? Give the formula for finding out lateral pressure on form work.
[4 marks]Find the lateral pressure using ACI formula for the wall of size 15 m, m, 0.2 m. Assume rate of pour is 10 m3/h and ambient temperature as 20°C. The product of Cw and Cc may be considered equal to 1.
[7 marks]For the data given below, compute the lateral pressure on formwork as per CIRIA formula and also draw the design pressure distribution. D (weight density of concrete) =25 kN/m3 C1 ( shape constant) =1 R, rate of rise =1 m/h C2, concrete constituent factor = 0.3 Temperature of concrete (°C) = 25 Temperature co-efficient = 0.77 H, form height = 6.15 m h,pour height = 6 m
