Class 11th Civil assignment 3 define concrete
Hello,
Concrete is a strong construction material made by mixing cement, sand, gravel (or stone chips), and water in specific proportions. When these materials are combined, the cement reacts with water and binds the sand and aggregates together to form a hard, solid mass. After setting and curing, concrete becomes durable, strong, and capable of bearing heavy loads. It is widely used for constructing buildings, roads, bridges, dams, and many other structures. Hope this helps!
