Concrete is not a homogeneous material like steel which is strong in both tension as well as compression. It is a composite material and is obtained by mixing cementing materials, water and aggregate and sometimes admixtures). Concrete is not able to resist direct tension (in comparison of its ability to resist direct compression) because of its low tensile strength and brittle nature.

Understanding Concrete's Strength Properties
Concrete is a widely used construction material known for its unique strength characteristics. It is essential to understand how concrete behaves under different types of loads.
Good in Compression
- Concrete exhibits high compressive strength, which means it can withstand significant loads applied in a downward direction without collapsing.
- This property makes concrete ideal for structural elements such as beams, columns, and foundations that primarily experience compressive forces.
Weak in Tension
- In contrast to its compressive strength, concrete has relatively low tensile strength. This means it cannot withstand significant pulling or stretching forces.
- When subjected to tensile forces, concrete is prone to cracking and failure. This weakness necessitates the use of reinforcement, such as steel rebar, to enhance tensile capacity.
Applications in Civil Engineering
- The combination of high compressive strength and low tensile strength influences design decisions in civil engineering.
- Engineers typically use a composite approach, where concrete is reinforced with materials like steel to balance its strengths and weaknesses, providing a more resilient structure.
Conclusion
- Option B, which states that concrete is "good in compression and weak in tension," accurately reflects these fundamental properties.
- Understanding these characteristics is crucial for effective structural design and ensuring the safety and durability of concrete constructions.
