Pneumatic Guniting & Shot Creting Machine Pneumatic Concrete Placer    
 
GUNITE is a process by which Plastering is sprayed at a high velocity. It is defined as mortar consisting of Cement and Sand, conveyed from the delivery equipment known as Gun through a hose and Pneumatically Forced through a nozzle where water is added at a high velocity onto a surface. The Force of the jet impacting on the surface compacts the material. A comparatively dry mix is gererally used so that the material is caplable of supporting itselg without sagging for vertical and overhead applications.
 
Equipment
Cement Gun with Rubber Hose and Nozzle
Twin Pressure water tank and water hose
Accessories
 
Uses
New Construction of thin sectons such as shells
Construction of thin walls
Canal and Tunnel lining
Swimming Pool linings
Repairing deteriorated Concrete and Concrete damaged by fire, chemicals or earthquake
Strengthening weak concrete structure such as Buildings, Bridges, Jetties
Stabilizing rock and earth slopes
Refractory linings
Encasing steel for fire proofing
Protective coating over prestressed wires and steel pipes
Repairs of Hydraulic Structures such as water tank, dam walls
To give rough surface texture where such is desired
 
Advantage
Due to the low water ratio and perfect compaction resulting from the high velocity of placement, Gunned Concrete have a greater density and because of the extreme density, it has proved to be an impervious Protective surface for concrete and steel structures
Gunned concrete bonds perfectly to properly prepared surfaces of other material such as concrete, brick, rock or steel
Gunned concrete cures to a product of extreme hardness and abrasive resistance and approx. 60% of maximum strength is attained in seven days. The following strength is attained in 28days by using ordinary washed sand with an approx, fineness modules from 2.415 to 2.90.
