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.

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. It can be defined as a steel bar or mesh strategically positioned within concrete elements to enhance their strength and resistance to tension forces. Concrete possesses excellent compressive strength, but it is relatively weak when it comes to handling tension. This is where rebar comes into play, acting as a reinforcement by adding tensile strength to the concrete. By distributing and absorbing tension forces, rebar enables the concrete to withstand bending, stretching, and twisting forces due to structural loads, temperature fluctuations, or seismic activity. Concrete structures would be vulnerable to cracks, fractures, and potential failure without rebar. Rebar is typically manufactured from carbon steel, which offers exceptional mechanical properties and a strong bond with concrete.

A lap is when two pieces of reinforcing bar rebar are overlapped to create a continuous line of rebar. The length of the lap varies depend on concrete strength, the rebar grade, size, and spacing. Contact splices—in which the bars touch and are wired together—are preferred because they are more secure against displacement during construction. Non-contact lap-spliced bars should not be spaced too far apart. For lap splice design and construction, the ACI Building Code requires the engineer to indicate locations and lengths of all lap splices on the structural drawings. Where reinforcing bars of two sizes are lap-spliced in tension, industry practice is to use the larger of the tension lap splice length for the smaller bar, or the tension development length for the larger bar. When bars of different sizes are lap-spliced in compression, the lap splice length must be the larger of the compression development length of the larger bar or the compression lap splice length of the smaller bar. Lap splices of 14 and 18 bars should not be used, except in compression only to 11 and smaller bars. Lap splices of bundled bars should be based on the lap splice length recommended for individual bars of the same size, and individual splices within the bundle should not overlap each other.

This research suggests that loss of reinforcement passivity, as the carbonation front progresses, occurs at a higher ph than previously thought. They are very helpful and friendly. The reaction of carbon dioxide and calcium hydroxide only occurs in solution and so in very dry concrete carbonation will be slow. He comments that a steel loss of only 0. There was a good selection for a small store. In saturated concrete the moisture presents a barrier to the penetration of carbon dioxide and again carbonation will be slow. Locations Mission.
