Read the following two statements I. Maximum strain in concrete at the outermost compression fibre is taken to be 0.0035 in bending. II. The maximum compressive strain in concrete in axial compression is taken as 0.002. Keeping the provisions of IS 456-2000 on limit state design in mind, which of the following is true?
The following two statements are made with reference to a simply supported under-reinforced RCC beam: I. Failure takes place by crushing of concrete before the steel has yielded. II. the neutal axis moves up as the load is increased. With reference to the above statements, which of the following applies?
Consider the following statements: I. Modulus of elasticity of concrete increases with increase in compressive strength of concrete. II.

The TRUE statements are
Consider the following statements: I. The compressive strength of concrete decreases with increase in water-cement ratio of the concrete mix. II. Water is added to the concrete mix for hydration of cement and work ability. III. Creep and shrinkage of concrete are independent of the water-cement ratio in the concrete mix. The true statements are
The state of two dimensional stress acting on a concrete lamina consists of a direct tensile stress, x = 1.5 N/mm2, and shear stress = 1.20 N/mm2, which cause cracking of concrete. Then the tensile strength of the concrete in N/ mm2 is
A concrete column caries an axial laod of 450 kN and a bending moment of 60 kM m at its base. An isolated footing of size 2m by 3m, with 3m side along the plane of the bending moment, is provided under the column. Centres of gravity of column and footing coincide. The net maximum and the minimum pressures in kN/m2 on soil under the footing are respectively.

Work ability of concrete can be measured using slump, compaction factor and Vebe time. Consider the following statements for work ability of concrete: (i) As the slump increases, the Vebe time increases (ii) As the slump increases, the compaction factor increases Which of the following is TRUE?
The modulus of elasticity, E = 5000 fck where fck is the characteristic compressive strength of concrete, specified in IS: 456-2000 is based on
Top ring beam of an Intze tank carries a hoop tension of 120 kN. the beam cross-section is 250 mm wide the 400 mm deep and it is reinforced with 4 bars of 20 mm diameter of Fe 415 grade. Modular ratio of the concrete is 10. The tensile stress in N/ mm2 in the concrete is
