Plastic concrete spacer

What is a plastic spacer?

Plastic concrete spacer is one of the most important side parts in reinforcement, which is used to create a standard distance between the rebar and the concrete form. The main purpose of using plastic spacers is to ensure the appropriate thickness of the concrete cover (concrete cover) on the reinforcements and increase the durability of the concrete structure.

## The importance of using plastic spacers in concrete structures

If spacers are not used, the rebars may come close to the concrete surface, which causes the rebar to rust, reduce the strength of the structure, and decrease the useful life of the building.

Plastic spacer prevents the following problems by creating a uniform and precise distance:

- Corrosion and rusting of rebar

- concrete cracking

- Reducing the compressive and bending resistance of the structure

---

## Types of concrete plastic spacers

### 1. Wall plastic spacer

Specific for the implementation of concrete walls and vertical molding, which makes the rebar stable in the standard position.

---

### 2. Foundation plastic spacer

It is used for floors, foundation and has a higher load tolerance.

---

### 3. Circular plastic spacer (rotary)

Suitable for columns and walls that are easily installed on the rebar.

---

### 4. Double and heavy plastic spacer

Can be used in industrial structures and projects with high loading.

## The advantages of plastic spacers compared to concrete and metal spacers

- Light weight and easy installation

- Resistance to moisture and chemicals

- No reaction with concrete

- Reasonable and affordable price

- Uniformity of concrete coating

---

## Applications of plastic spacer

- Foundation and foundation of the building

- concrete beam and column

- Shear walls

- prefabricated concrete structures

- Flooring and concrete slabs

---

## The role of plastic spacer in increasing the durability of the structure

The correct use of plastic spacer causes:

- Increasing the useful life of concrete

- Reducing the penetration of moisture and corrosive substances

- Preventing the rebar from reaching the concrete surface.

- Complying with the requirements of concrete cover regulations

It will.

Standards related to plastic spacers

Quality spacers should conform to:

- EN standard

- ACI Regulations

- Iran's national building regulations

be produced and used.

---

## Important points in choosing a plastic spacer

- type of structure (foundation, wall, column)

- The amount of concrete cover required

- rebar diameter

- environmental conditions of the project

- The quality of polymer raw materials

---

## Plastic spacer price

The price of plastic spacer depends on various factors such as:

- Spacer type and model

- cover thickness

- Quality of raw materials

- order number

It depends. Buying directly from the manufacturer reduces costs.

Summary

Plastic concrete spacer is one of the essential components in the correct implementation of reinforcement, which, by creating a standard distance between the rebar and the mold, plays an important role in increasing the strength and durability of concrete structures. Choosing the right spacer will guarantee the final quality of the construction project.
