Comment. 3

b) Which cement will you recommend for
concrete
permeability concrete
strength concrete 3
(ii) Which type of cement concrete you will recommend for 'blast resistance purpose' and why 2

(iii) Illustrate briefly one estimation method for one bedroom house. 5
(iv) Which compaction and consolidation equipment you recommend for quick construction of a high rise building and why? Briefly discuss factors contributing to the ownership cost of a heavy construction equipment. 3
(ii) Briefly elaborate the factors contributing to the rental value of a heavy construction equipment. 3

(iii) Explain the functions of in river regulation. Also state the parameters on which design of spur depends. During a particular stage of growth of a crop, consumptive use of water is 3·2 mm/day. Determine the interval between irrigations and depth of water to be applied when the amount of water available in the soil is 35% 75% and of the maximum depth of available water in the root zone which is 100 mm. Assume irrigation efficiency to be 60%. 12

(e) Explain the impact of flood wave on river water levels and flood travel time and explain the terms 'prism storage', 'wedge storage' and 'Negative wedge storage' with a suitable sketch. Also write an equation for flood routing where storage is expressed as a function of inflow and outflow in the river reach. 12
2. A small CPM network has the following data. Establish the optimum schedule for minimum cost, and minimum duration if the indirect cost is 3000 rupees per day and all normal total direct cost is 2,00,000 rupees only.
