Concrete is among the world’s oldest and most widely used building materials because of its relative affordability, wide availability, extended lifespan, and resilience in the face of adverse climate conditions. Concrete output surpasses steel production throughout the globe by a factor of 10. However, alternatives to concrete, like as steel and polymers, are both more costly and less widespread in the building industry. Concrete has the high compressive strength but the low tensile strength, making it a brittle material. Therefore, tensile strains can only be handled by reinforced concrete. Concrete, depending on its curing condition, may be either pliable or solid, making it a very adaptable construction medium. Aggregates and rocks are blended with fluid cement to create this. Concrete undergoes a hydration process that causes it to harden into the rock-like mass over a period of time. Once hardened, its strength increases to 3,000 to 20,000 psi, making it suitable for use in the construction of dams, skyscrapers, as well as bridges. This book discusses about how the buildings, roads, and bridges all benefit from concrete technology for the production of columns, beams, slabs, and the other load-bearing elements. Concrete may be made using a wide variety of cements. Concrete is typically made using Portland cement. In concrete, many binding materials are employed.
