During concrete works, one detail that often goes unnoticed by non-engineers is the rebar chair. These small supports hold reinforcement bars at the correct height before and during concrete pouring. To many workers, rebar chairs seem insignificant, but to engineers, ...

How to Use Rebar Scanners to Locate Steel Before Drilling?
When drilling or coring into reinforced concrete, it’s critical to know what lies beneath the surface. Accidentally hitting a reinforcement bar (rebar) or embedded conduit can cause costly damage, weaken the structure, and pose serious safety risks.To prevent this, engineers ...
Hemp Rebars: Low-Cost Non-Corroding Reinforcement
A team of researchers from the Rensselaer Polytechnic Institute (RPI), USA, has invented hemp-based rebar as an alternative to traditional steel reinforcement for concrete structures. The study claims that hemp rebars for concrete reinforcement mitigate the problem of corrosion and ...
What are Rebar Shakers?
A rebar shaker is a vibratory device attached to steel bars which turns them into a vibratory instrument to consolidate the concrete. It is designed to compact concrete in reinforced concrete elements that cannot be reached easily, such as congested ...
Tata Steel to Manufacture ‘Green’ Rebar for a Sustainable Future
Indian steel giant Tata Steel is set to develop a GreenPro framework for steel rebars, a-first-of-a-kind initiative in India. The company will undertake the development in collaboration with the Confederation of Indian Industry (CII) Green Business Centre and other relevant ...
Magnetic Rebar Locator – Covermeter Test Applications and Precautions
Magnetic Rebar Locator (Covermeter) Test gives information about concrete cover to steel reinforcement using magnetic fields. Pachometer device is used to get information about location of reinforcement bars in concrete.
Placement of Rebar in Footings – Horizontal and Vertical Rebars
Steel reinforcement forms an important part of concrete foundations. Thus, good placement of horizontal and vertical rebars in a footing is of utmost importance as placing concrete. The placement, size, cover, tying and tolerance in steel reinforcement are considered to ...
What is Rebar? Types and Grades of Steel Reinforcement
What is Rebar? Steel reinforcement bars or rebars are used to improve the tensile strength of the concrete, since concrete is very weak in tension, but is strong in compression. Steel is only used as rebar because elongation of steel ...
