Concrete construction involves the use of concrete, a strong and durable material made from a mixture of cement, water, and aggregates like sand and gravel. This method is widely used for building structures such as foundations, walls, and floors due to its ability to withstand heavy loads and resist weathering. The process typically includes pouring the concrete into molds, allowing it to set and cure, which hardens the material. Various techniques, such as reinforcement with steel bars, can enhance the strength and longevity of concrete structures. Overall, concrete construction is essential for modern infrastructure and buildings.
