Cover blocks Making Machine – The Ultimate Guide -2020

What Is Cover Blocks?

Concrete cover blocks are used cement, sand, water as materials. After materials are mixed, it is formed in the cover block making machine or by plastic block mould.

It is generally used to elevate the rebars in the precast concrete to prevent the reinforcing bars from sticking to the bottom of the concrete parts.

Or tie it to the side of the rebar to prevent the rebar from sticking to the edge of the concrete product, so that when the concrete is poured, the steel bar will not be exposed and be oxidized and corroded.


Why Do You Need To Use The Cover Blocks?

If you do not use a cover block, the steel bars will be exposed to the air, and atmospheric moisture will corrode the concrete reinforcing bars, causing the rebars to gradually rust, and the load-bearing capacity will also decrease, making the entire rebars structure invalid.


What Is The Application Of Cover Block?

  • Ensure that the rebar has enough steel protection layer, so that the reinforcing bar is in the best stress position, and at the same time extend the service life of the rebar to prevent premature corrosion.
  • Advantages: Due to the use of cushions with equal structural strength, it has no major impact on the structure. Compared with other cushions (reinforced cushions, plastic cushions, etc.), the quality is stable and should not be damaged, and the cost is low and suitable for obtaining materials.

What Are The Features Of Concrete Cover Blocks?

  • High-strength concrete material with compressive strength greater than 60Mpa. It is not easy to be broken, and its practicality is much higher than that of other materials.
  • The expansion coefficient is the same, the durability is high, the material used is the same as the high-performance concrete, the expansion coefficient is the same, and the adhesion is high.


  • Even steam curing will not produce gaps, it can be fully integrated with concrete, which can effectively prevent the concrete from falling off due to the corrosion of steel bars caused by the penetration of air, rain, sea water, etc., and greatly improve the durability and safety of reinforced concrete.
  • The bottom arc contact surface is small, the color difference after demolding is small, the contact surface between the cushion block and the template is small and the stability is high.
  • The construction is simple and quick, and the hole-shaped cushion block can be fixed to the steel bar only by piercing the iron wire.
  • Use high pressure hydraulic press machine to form the cover blocks, and the shape of blocks are same dimensions.

How To Use The Cover Blocks In Construction?

  • The spacing of the spacers is to ensure the separation of the steel bar and the construction formworks; the spacing is about 300-800mm.
  • In road construction, there are no less than 6 cement cover blocks per square meter placed on the horizontal plane, and no less than 4 concrete cover blocks per square meter placed vertically;
  • In a frame building, it should be divided into different situations. The spacing between the cover blocks on each side of the column is about 1 meter; the cover blocks for the shear wall are about 0.5-1 meter; the cover blocks for slabs are about 0.5 meters;

  • C7.5 or C10 concrete is generally used as the cushion in the building. When there is a cushion, it is 40mm and when there is no cushion, it is 70mm. Both sides of the cushion should extend 50mm from the base plate.
  • According to the regulations for the design of reinforced concrete structures, the minimum thickness of the protective layer of beams and columns is 25mm. The thickness of the board and wall protection layer is 10-15mm.

What Are The Requirements For A Qualified Cover Block?

  • It should have sufficient strength, not easy to break, corrosion resistance, size standards and meet the requirements.
  • It combines well with concrete, has the same expansion and contraction performance, and is simple to connect with rebars without falling off.
  • The color is close to the concrete, and the volume is as small as possible. The larger the volume size of the cover blocks, the more difficult it is to obtain a consistent concrete pouring effect.


How To Make The Concrete Cover Block? – Cover Block Manufacturing Process

Cover blocks are similar with cement blocks, they are mainly made of concrete mixture as raw materials and made by brick making machines. Because the concrete brick machine can produce concrete bricks of various specifications, you only need to change the mold.

The material

Their raw materials can be 425 cement or 525 cement, coarse sand or medium sand, and the ratio of water, sand and cement is 4-6. You can also refer to the ratio of concrete bricks.


It can be used to mix raw materials through a mixer. The small brick machine is equipped with a small mixer, JQ350, JQ400

Large-scale automatic concrete cover brick machines need to be equipped with JS series mixers.

For specific configuration, you can configure the cover block production line according to the output you need.

Moulding – cover block machine

You can choose to use cover block making machine to produce cover blocks. Feed materials enter the mold, the upper mold is pressed down, and the lower mold is vibrated by a vibration motor to increase the density of the raw materials. Produce high-quality, high-strength cover blocks.


The formed cover block is stacked using a stacking machine, and then cured.

What you should pay attention to here is that, depending on the difference in machine configuration, many manufacturers deliberately report low prices first in order to attract people with low prices, and then provide you with low-configuration equipment.

And the quality of machines from different manufacturers is also very different. Therefore, the price is only a reference factor.

The most important thing is that you must first find a professional cover block making machine manufacturer, then find the equipment that suits you, and then discuss the price with the manufacturer.

Cover blocks VS Concrete Blocks

Concrete Blocks: this is blocks are made of sand, cement, ash, stone powder and water. The concrete blocks can be concrete hollow blocks, concrete solid blocks, concrete interlocking bricks, concrete cover block. The cover blocks is one type of concrete blocks.

What Types Of Cover Blocks Are Common Used For Construction?

According to the different materials of cover blocks, it can be divided into: concrete cover block, PVC cover block, steel cover block, stone cover block, and aluminum block.

In order to save costs, we are increasingly inclined to use concrete cover blocks.

What Is Size Of Cover Blocks?
