Carbonation is the single most common cause of reinforcement corrosion in above ground structures and although many construction professionals and contractors are familiar with the progression of carbonation through concrete and the consequential effects on reinforcement, some may not be familiar with research carried out in recent years. This research suggests that loss of reinforcement passivity, as the carbonation front progresses, occurs at a higher ph than previously thought. The ph of new concrete is typically , which surrounds embedded reinforcement with a passivating layer of highly alkaline cement, protecting reinforcement against corrosion. The reaction produces calcium carbonate. This reduces the alkalinity of the concrete to a level where the cement paste no longer provides a passive environment for embedded steel, this is said to occur when the ph of concrete falls to approximately 8. Steel reinforcement is then though to be susceptible to corrosion. The reaction of carbon dioxide and calcium hydroxide only occurs in solution and so in very dry concrete carbonation will be slow.

Rebar plays a critical role in concrete construction. It provides tensile strength to the concrete, which is necessary to resist the forces of tension and compression that a structure is subjected to during its lifetime. Without rebar, concrete would be unable to withstand these forces, leading to cracking, deformation, and, ultimately, structural failure. In essence, rebar is the backbone of the concrete, ensuring its structural integrity and longevity. Therefore, selecting the appropriate rebar type and size, and ensuring proper installation, is crucial to the success of any concrete project.

Rebar is an essential element in construction, serving as a critical reinforcement for concrete structures. This comprehensive article delves into various aspects of rebar, offering an in-depth understanding of its definition, historical significance, manufacturing process, grades, sizes, types, installation techniques, and inspection methods. By exploring these essential aspects, you will gain valuable insights into the significance of rebar in the construction industry, its role in enhancing the strength and durability of concrete structures, and the importance of proper understanding and implementation of rebar technology. Rebar, short for reinforcing bar, is a critical component in construction, serving as a backbone for concrete structures.
