What is Concrete?

The article underscores concrete’s vital role in contemporary civil engineering due to its durability and ease of use. It delineates concrete as a composite of cement, aggregates, sand, and water, solidifying via hydration. Highlighted are its properties, such as brittleness and inferior tensile strength compared to compression, with reinforcement suggested as a solution. Briefly outlined are the key components: cement, coarse and fine aggregates, water, and admixtures. Structural concrete is categorized into plain, reinforced, and pre-stressed variants, each serving distinct purposes. Plain concrete, suited for gravity structures like dams, lacks reinforcement, while reinforced concrete, incorporating rebar, enhances tensile strength. Pre-stressed concrete, subject to pre-applied stress, augments load-bearing capacity significantly. In sum, the article furnishes a concise synopsis of concrete’s constitution, attributes, and widespread application in civil engineering, underscoring its significance in modern construction endeavors.
