103. Reason for concrete being weak in tension?
Concrete is a combination of materials like several aggregate types, cement, pozzolana, water, air, etc which are stick together with a cement paste. The zone called the “interface zone” is the weakest link in the structure. During compression, that interface is the only to transfer compressive stresses from aggregate to aggregate. Which does not require exceptional strength.
While the scenario under tension is not the same. The aggregates in tension are trying to pull away from each other and the bond is what holds it tightly. Since it is significantly weaker than the aggregates, it is what results in failure.
