For the following questions answer them individually
The modulus of Rupture of concrete in terms ofits characteristic cube compressive strength $$f_{ck}$$ in Mpa according to 1S456 — 2000 is
For limit state of collapses, the partial safety factor recommended by IS456 — 2000 for estimating the design strength of concrete and reinforcement steel are respectively
Six columnsofbuilding are to be located within the plot size of 15x10m. The expected load on each column is 600 KN. Allowable bearing capacity of soil is 120 $$\frac{KN}{m^{2}}$$
The type of foundation to be used is
A clay soil sample is tested in tri-axial apparatus in consolidated drained conditions at a cell pressure of $$\frac{100 KN}{m^{2}}$$ What will be the pore water pressure at a deviator stress of $$\frac{40 KN}{m^{2}}$$
The number of blows observed in a standard penetration test (SPT) for different depth are given below:
The observed ‘N’ value is
A sampling tube has an inner diameter of 80 mm and outer diameter of 88 mm. The area ratio is
A compacted sample of soil with bulk density of $$2.0 g/cm^{3}$$ has a water content of 15%. What is its dry density? Assume G = 2.65
A wet sample of sand weighing 415g is taken for water content determination by a pyconometer. The mass of pyconometer, sand and water is 1667g and mass of pyconometer full of water alone is 1440g.Assume G = 2.67. Determine water content.
