Questions (page 2)
Q2. What are the causes and remedies of efflorescence in bricks? (6 marks)
Q3.
Explain the specific reasons for the following:
(i) For prestressed concrete, the Code recommends to use high tensile steel and high strength of concrete. (6 marks)
Q4.
Explain the specific reasons for the following:
(ii) Helically reinforced circular columns have better compressive strength than that of similar columns with lateral ties. (6 marks)
Q5. The rafter member of a truss consists of two angles ISA 75×75×8 placed back-to-back on both sides of the gusset of thickness 10 mm. It carries factored axial compressive force of 200 kN. Determine the number of 16 mm diameter, 4.6 grade ordinary bolts for the joint. Assume E250 grade of steel and the cross-sectional area in the threaded part for 16 mm diameter bolt is 157 mm2. Use Kb = 0.49, γ_mb = 1.25. Use limit state method of design. (12 marks)
Q6. A bar specimen of 38 mm diameter was subjected to a pull of 98 kN during a tensile test. The extension on a gauge length of 200 mm was measured to be 0.092 mm and the change in diameter of 0.0048 mm. Determine the Poisson's ratio, modulus of elasticity, modulus of rigidity and bulk modulus of the material of bar specimen. (12 marks)
Q7. With the help of neat sketch of a typical grading curve, describe the term 'gap-graded aggregate' and the adverse effects of using such type of aggregates in concrete. (6 marks)
Q8. How is PPC different from OPC on the basis of their ingredients? Describe the advantages of using PPC in comparison to OPC. (6 marks)
