Tensile Strength Test

Q. The split tensile strength of $M15$ grade concrete when expressed as a percentage of its compressive strength is

1. $10$ to $15\text{\%}$
2. $15$ to $20\text{\%}$
3. $20$ to $25\text{\%}$
4. $25$ to $30\text{\%}$

Q. The ratio of tensile strength to compressive strength of concrete is about

1. $\frac{1}{10}$
2. $\frac{1}{2}$
3. $\frac{1}{20}$
4. $\frac{1}{5}$

Q. Tensile strength of concrete is measured by

1. direct tension test in the universal testing machine
2. applying compressive load along the diameter of the cylinder
3. applying third point loading on a prism
4. applying tensile load along the diameter of the cylinder

Q. The tensile strength of concrete is approximately what present of compressive strength of concrete

1. $50\text{\%}$
2. $20\text{\%}$
3. $10\text{\%}$
4. $5\text{\%}$
