Q1. Q1. What are the oxide compositions of Ordinary Portland Cement ?
- (a) Mention the typical percentage ranges for each one of them.
- (b) With respect to the Construction Project Management, what are the various types of costs associated with a project? Draw a graphical representation of project cost curves.
- (c) How are cranes categorised into different classes ? Also explain in brief the application of cranes in construction projects.
- (d) Design a turnout taking off from a MG straight track for 1 in 8½. Crossing number with an angle of switch 1°28'00". Take heel divergence as 11.75 cm. Show all the values on a neat sketch.
- (e) A steel tape of 30 m nominal length was used to measure a line AB by suspending it between supports at A and B. The length between A and B was measured as 28.765 m with tape making slope angle 4°15'. The tension applied was 80 N and the temperature was 5°C. Determine the corrected horizontal length between A and B. Assume the following data: Standard temperature 20°C; Standard tension 50 N; Weight of tape 0.2 N/m; Cross-sectional area = 2 mm2; Modulus of elasticity = 12 × 109 N/mm^2; Coefficient of expansion; Two tangents intersect at chainage 40 chains and 50 links, the deflection.
