Some useful processes to resist corrosion in steel reinforcement

In order to resist damage and failure of concrete structures, steel reinforcement Corrosion control methods are undertaken. Near about forty percentage of collapsing of concrete structures occur due to corrosion of inner steel reinforcement.

There are various reasons for the corrosion of steel reinforcement which range from the quality of concrete, atmosphere, and quality of construction practices.

Initially, it is required to arrange superior quality of concrete via good construction practices to manage corrosion in rebar. To manage rebar corrosion, the focus should be given on various factors like the quality of concrete materials, mixing, placing and compaction methods and good workmanship.
Quality control in concrete construction minimizes the scopes of corrosion. By applying the following methods, the corrosion of reinforcement bar can be controlled efficiently.
Steel reinforcement corrosion control processes :-
• Cement-Polymer Composite Coated Rebars (CPCC)
• Fusion Bonded Epoxy Coated Rebars (FBEC)
• Corrosion Resistant Steel Deformed Rebars (CRSD)
1.Cement-Polymer Composite Coated Rebars (CPCC): Cement polymer coat rebar implanted in concrete are encircled through an alkaline medium. A cement base coating is very effective in controlling reinforcement corrosion. Two coats of cement polymer are used on rebar like first Primer coat and a sealer coat.
Products contained in Cement Polymer Composite Coated rebar are:
• De-rusting Solution
• Alkaline Powder
• Phosphating Jelly
• Inhibitor Solution
• Sealing Solution
2. Fusion Bonded Epoxy Coated Rebars (FBEC): Fusion bond epoxy coat rebar is formed with 100% solid delicately grounded fuse powder particles. These particles are dissolved through heating to develop a permanent adherent film. There is not any passivating primer film contained in FBEC rebars. It produces a medium of weakness in the path of an intimate bond among rebar and alkaline concrete.
Epoxy provides the coating to the rebar with the following :-
• Melts
• Flows
• Gels
• Cures
• Cools
• Adheres to coating
3. Corrosion Resistant Steel Deformed Rebars (CRSD): Under this method, an initial layer of protective oxide or rust is created to resist the corrosion. On general rust on normal rebars, the CRSD rust is passive, persistent and self-renewing. The preventive oxide is fine texture, tightly adherent and a barrier to moisture, oxygen, carbon dioxide, Sulphur dioxide. The chloride provides protection against corrosion.
It is suggested to employ corrosion resistance Steel Deformed Rebars to resist corrosion of concrete structures, damage, and collapsing of concrete structures.

Discussion is made on how to select among and utilize the alternative procedures for repairing or sealing cracks in masonry surfaces like poured concrete floor slabs, concrete foundation walls, or brick or masonry block foundation walls. Application of epoxy sealants, polyurethane foam sealants, and hydraulic cement crack repair sealants.
This article series also explains how to identify and analyze different types of foundation failure or damage, like foundation cracks, masonry foundation crack patterns, and moving, leaning, bulging, or bowing building foundation walls.
Types of foundation cracks, crack patterns, variations in the meaning of cracks in several foundation materials, site conditions, building history, and other evidence of building movement and damage are explained to facilitate identifying foundation defects and to allow the inspector for isolating cosmetic or low-risk conditions from those expected to be crucial and potentially costly to repair.
The focus is also given on a list of materials utilized to fill poured concrete slab control joints. Also learn how to seal a cracked masonry foundation wall or floor slab. Typical concrete crack groundwork for sealant with an epoxy product.

Brief overview of various building elements necessary for reinforced concrete structure

1st Floor: It belongs to the floor that contains 1 storey height over ground.

Basement Floor: The floor that is located at basement of the building. It is also known as cellar. The basement floor is situated either entirely or partly underneath the ground floor. A basement is utilized closely in the similar way like a supplementary above-ground floor of a house or other building.

The application of basements mainly based on several factors associated with a specific geographical area like climate, soil, seismic activity, building technology, and real estate economics.
The concrete floor in most basements is not included in the foundation structurally except the basement walls. With the surge of warm air, basements are normally cooler compared with the remaining part of the house. In summer, it makes basements damp, because of the greater relative humidity.
Basement Wall: The wall that encircles the basement floor is known as the basement wall and it considered as a vital portion of the foundation structurally. The basement walls stands for shear walls which have the ability to withstand the lateral loads also. Besides, these walls are considered as highly non-porous and water-defiant.
Column Bracket: Column Bracket is over hanged from the column and it is useful for hanging or affixing lamps, bulbs or other accessories to it similar to road signs.
Column Capital: Column capital belongs to an architectural element that is utilized for aesthetic purposes to develop the uppermost member of a column.
Drop Panels: The objective of drop panels is to solidify the slab around the column in flat slabs to get rid of punching shear. As flat slabs do not contain stirrups, shear is defended by solidifying the slab around the column to raise the concrete in shear. Beams are also applied, but normally drop panels are most effective to get rid of conflicts with the electro-mechanical works of the structure.
Exterior Columns: These are the columns which provide support to the primary structure of the building. Normally in frame structures, the exterior columns are very crucial and sustain the load of the building as well as withstand environmental factors like wind, rain, and other physical factors.
Flat Plate: These are the slabs to be attached with the columns directly. Flat plate system is mostly recognized by the engineers as it offers huge benefits. The system can curtail the height of the building, offer more flexible spatial planning as there are no beams. It also minimizes the material cost significantly. But the issue is that it can be easily broken and may collapse against punching shear. Because of the comparatively small floor loading and the tight column spacing, flat plate construction is getting popular.
To combat greater loading and larger column spacing, column capitals are necessary, and for even bigger spans to decrease the self-weight, waffle slabs are required.

Placement of lap in column as per IS Code 13920

This construction video tutorial sheds light on reinforcement lapping zone in column. By going through this video, one can learn how to place lap in exact position in column by adhering to IS code 13920.

A lap is required when two pieces of reinforcing bar (rebar) are overlapped to produce a constant line of rebar. The length of the lap fluctuates according to the concrete strength, the rebar grade, size, and spacing.

The objective of lap is to transmit load from one bar to another bar as well as retain continuity. The positioning of lap is dependent on the bending moment of the column.
Lap length refers to the length of the overlap of bar necessary to securely transmit stress from one bar to another. Lap length varies on the basis of tension and compression zones and mostly relies on grade of concrete and steel. Development length refers to the length of the bar necessary to transmit stress from steel to concrete.
Rebars in column should have been lapped at around 5 feet from the story.
As stated by I.S. 13920 Vertical bars of Columns should be lapped in regular zone (Mid-height ) only and it should be spread out i.e. not surpassing 50% of bar is lapped at one section. Besides, lowest clear vertical distance among lapped bars should be 0.25 times lap length.
To get more details, watch the following video tutorial.
