How can Rebar wastage be reduced?
Loss of rebars can be minimized with minimum use of discrete bars in market length. In order to achieve this goal, the accurate and detailed information of rebars is extracted, followed by both rapid and efficient bar combination.
What is rebar wastage?
A major waste stream in construction of concrete structures is the steel reinforcement waste generated during cutting of steel rebar to their final required lengths.
How do you measure reinforcement bar quality?
The quality check of the reinforcement bars brought to the site can be performed by following inspection and tests:
- Compare the manufacturer test certificate.
- Check the grade of the steel in the manufacturer certificate and look at whether it is as per the order.
- Check for rust and unwanted debris on it.
How do you store reinforcement steel?
Bundles of reinforcement should be stored in a clean location, off the ground and away from mud and oil. They should be stacked with sufficient timber supports so that the bars do not buckle, bend or sag. The bundles should be clearly identified so that they can be easily found when required.
How do you reduce wastage in steel?
So depending on the cost of steel and resale value of scrap steel, lapping may be costlier if the off cut is less than a certain length. Pre calculate this length for each diameter. Using full length bars will reduce laps and so reduction in steel wastage.
Is code steel wastage?
Allowable wastage for steel works is 3 \%( i.e. cutting/bending wastage).
What is the difference between rebar and steel?
Steel is a generic product, it goes into many things. Rebar is slang or shorthand for reinforcing bars. Rebar is typically made of steel, though there are other products available such as fiberglass. Rebar also has a specific purpose, and that is to provide tensile strength to concrete cross sections.
How do you store reinforcement bars?
Put the rebar on top of a raised non-metallic platform, such as wooden pallets. Both the ground and concrete areas absorb moisture and can lead to rusting. Cover the rebar with a thick protective tarp and secure it with cinder blocks (or something similarly heavy) at the corners and edges.
How do I store reinforcement on my website?
FAQs
- Stack the materials off-ground using a suitable platform.
- Do not keep in contact with carbon steel or other rebar material.
- If the contact with ferrous rebars is inevitable, then place it on the top.
- Cover the stainless steel rebars using a polyethylene sheeting when stored outside.
How is wastage of steel bar calculated?
For RCC works the wastage is 2.5\% for reinforcement rods above 36mm dia. and 5\% for rods below 36mm dia. including overlaps, if they are not welded. If welding is adopted for the reinforcement rods even for below 36mm dia, 2.5\% of wastage is recommended.
Is code for wastage of reinforcement steel?
