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. Brittleness of concrete increases with decrease in compressive strength of concrete. III. Shear strength of concrete increases with increase in compressive strength of concrete. 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.
