The Working Principle of Pneumatic Concrete Spraying Machines

Concrete Preparation: A homogeneous concrete mortar is prepared by mixing water, cement and aggregates. The prepared mortar is immediately taken into the spraying process without losing its water.

Spraying Process: The prepared concrete mortar is transported to the spray gun with the help of high-pressure air. No water is added to the spray gun.

Hardening: The sprayed concrete mortar forms a solid concrete coating by coming into contact with moisture in the air and hardening under the influence of hardening additives.

Advantages of Pneumatic Concrete Spraying Machine

Less water use: It is an environmentally friendly method with less water use compared to wet concrete spraying.

Faster drying: Wet concrete dries faster and speeds up the workflow compared to spraying.

Less rebound: The sprayed concrete has less risk of bouncing back.

Higher strength: In certain situations, concrete coatings with higher strength can be obtained compared to wet concrete spraying.

Less dust and dirt: It provides less dust and dirt formation compared to wet concrete spraying.

Areas Of Use

Tunnels: It is used for coating and strengthening of tunnel walls.

Mine Galleries: It is used for coating and strengthening the walls of mine galleries.

Pools: It can be used in the interior and exterior coatings of pools.

Dams: It can be used on the inner and outer coatings of dams.

Buildings: It can be used in the foundations of buildings, basements and behind curtains.

Stabilization of rocky slopes: It can be used to prevent the collapse of rocky slopes.

Water tanks: It can be used in the interior and exterior coatings of water tanks.

Sea walls: It can be used in the construction of sea walls.

Frequently Asked Questions About Pneumatic Concrete Spraying Machines

• What is the difference from wet concrete spraying?

In air concrete spraying, water is not added after concrete spraying, while in wet concrete spraying, water and concrete are sprayed together.

• What equipment is required for pneumatic concrete spraying?

Concrete mixer, pump, spray gun, compressor and other auxiliary equipment are required for air concrete spraying.

• How is air concrete spraying done?

Air concrete spraying should be carried out by an experienced team. It is important to have information about the use of the machine and safety measures.
