Introduction to Concrete Spacer
When building something today, everything hinges on getting materials like concrete to work right. One of the most overlooked components of any construction job is the Concrete Spacer, but this little piece of equipment does a lot to help you achieve precise and durable results. When you’re constructing either a residential slab, a commercial building, or an industrial-sized project, properly positioning your reinforcement bars (rebar) is very important, and that’s where spacers come into play.
A Concrete Spacer provides an accurate distance from the rebar to the forms (the surfaces that hold the concrete while it sets). By using a spacer properly, you will ensure that the rebar is within the proper distance from the forms and that the resulting concrete cover is also correct. Using spacers improves the strength of the overall structure and creates fewer issues over the long term (e.g., corrosion, cracking).
Even though Concrete Spacers are small in their overall contribution to the construction process, their impact is that of a much larger component.
At BIN Hammad we carry a full line of high-quality materials that have been manufactured to conform to any and all industry standards — so please keep reading and learn more about Concrete Spacers by reviewing the information in this guide to Concrete Spacers, including the different types of Concrete Spacers, their benefits, proper methods for installation and some other points of interest.
What is a Concrete Spacer?
Definition of Concrete Spacer
In the construction industry, a concrete spacer is used so as to stabilize the position of reinforcement bars (rebar). They are small support pieces so as to maintain a specific space between the rebar and the formwork. This space ensures that the concrete will have an even amount of concrete cover around the rebar, thus protecting the reinforcement from rust.
Purpose of Concrete Spacer
Maintaining Correct Concrete Cover
The purpose of spacers is to maintain enough distance between the concrete and rebar so that the rebar is adequately surrounded by concrete.
Preventing Corrosion
Protecting the rebar by positioning the rebar at the correct distance from the concrete will keep the rebar safe from corrosion resulting from exposure to air and moisture.
Different Types of Concrete Spacers
Each type of construction project requires a different type of concrete spacer. The type of concrete spacer used will depend on the type of structure being built so as the weight of the load being carried.
Plastic Concrete Spacers
Plastic concrete spacers are light and low-cost and are easy to use. They are commonly used in both residential and commercial construction.
Concreteness Cover Block
These blocks are made out of cement so as to provide a high level of strength and durability.
Metal Concrete Spacers
Metal spacers are used in construction projects that will be carrying heavier loads.
Wheel Concrete Spacers
Wheel spacers are recommended for vertical support, such as in walls or columns.
Key Features of Concrete Spacers
Good Quality Concrete Spacer
A good quality concrete spacer should be capable of supporting heavy reinforcements without collapsing when concrete is poured.
Durable
Concrete spacers are designed to withstand the pressure exerted onto them by the weight of the concrete being poured over them.
Corrosion Resistant
Spacers protect rebar from damage due to the environment.
Easy to Install
Concrete spacers are easy to place and require little to no effort to install.
Accurate Spacing
Make sure that reinforcement is positioned exactly and consistently.
Concrete Spacer Advantages
Reinforcement Position Maintenance
The concrete spacer will keep the steel reinforcement bars in their positions as concrete is being poured.
Structural Improvement Strength
The overall strength of the structure will increase because of properly placed reinforcement bars.
Prevention of Steel Corrosion
Concrete spacers that are positioned correctly will help prevent moisture from affecting the steel.
Ensures Uniform Concrete Cover
Having a uniform cover and protection on the steel will increase durability and performance.
Increased Longevity
When steel is placed correctly in structures, they will last longer than those that are not placed correctly.
Uses of Concrete Spacer
Slabs
Concrete spacers are utilized for holding the steel in position while the concrete is poured in the floor slabs.
Columns
Concrete spacers are used to keep the vertical reinforcement in positions while the concrete is poured.
Beams
Concrete spacers are used to add support to the horizontal reinforcement while concrete is being placed.
Foundations
Concrete spacers play a vital role in maintaining a proper cover on any foundation structure.
Precast Structures
Concrete spacers are used to hold the steel and align the steel in factory-made concrete elements.
Construction Material Handling
When constructing projects that require additional materials ex. interlocking bricks, concrete spacers are essential to keeping the reinforcement in place to support the weight load.
Concrete Spacer Selection Considerations
Type of Structure
Different types of structures require different types of concrete spacers.
Weight Load Requirements
Concrete spacers should be able to accommodate the weight load of the reinforcing steel.
Environmental Conditions
When selecting concrete spacers, environmental conditions, such as exposure to moisture or extreme temperatures should be taken into consideration.
Size and Thickness
When selecting concrete spacers, the size and thickness of the concrete spacers should be considered to ensure a proper cover on the reinforcing steel.
Concrete Spacer Installation Process
Surface Preparation
Ensure the surface is clean and level before installation of concrete spacers.
Placement of Concrete Spacers
The installers should position the concrete spacers evenly across the complete reinforcement grid.
Securing Reinforcement
Installers will ensure that the reinforcement bars are secured firmly to the concrete spacers.
Pour Concrete
As you are pouring, do not let the concrete displace the spacers.
Common Mistakes to Avoid (for Spacers)
Using Incorrect Sized Spacers
If you use an incorrect size of a spacer, it will affect the concrete cover.
Improperly Placing Your Spacers/Materials
If you put spacers in unevenly, you will have weak structures.
To use High Quality Materials
Always purchase a high quality spacer (or material) so that it will last and perform well.
Maintenance and inspection
Checking the Alignment
Before pouring, ensure that the spacers are in their correct position.
Assess the Stability of the Reinforcement
Make sure the reinforcement is stable.
Material Quality Inspection
Check the materials prior to use, to ensure quality.
