Question

What is the percent of the tensile strength of unreinforced concrete in relationship to the compressive strength of unreinforced concrete?

1) 10 percent
2) 20 percent
3) 25 percent
4) 50 percent

Answer 1

The tensile strength of unreinforced concrete is typically about 10-15 percent of its compressive strength. This difference in strength is due to the nature of concrete as a brittle material, meaning it is prone to cracking and breaking under tension.

Step-by-step explanation:

The tensile strength of unreinforced concrete is typically about 10-15 percent of its compressive strength. This means that the tensile strength is considerably lower than the compressive strength.

For example, if the compressive strength of uncreinforced concrete is 20 × 10^6 N/m², the tensile strength would be around 2-3 × 10^6 N/m².

This difference in strength is due to the nature of concrete as a brittle material, meaning it is prone to cracking and breaking under tension.
