Shotcrete is a fast and effective reinforcement method that has evolved from roadway support technology to the reinforcement of above-ground structures. It has its own unique advantages: Shotcrete uses a shotcrete machine and compressed air as power to transport a certain proportion of the mixture through a high-pressure pipeline and spray it onto the sprayed surface at a high speed.
The spraying speed of concrete from the nozzle can reach 60m~80m/s. It depends on the repeated and continuous impact of cement and aggregate during high-speed spraying to compact the concrete. Due to the small water-cement ratio (0.4-0.5), it has high bonding strength with concrete, masonry, and steel. It can be used in combination with steel mesh to transfer tensile stress and shear stress on the bonding surface. Higher mechanical properties and good durability can greatly improve the bearing capacity of the masonry and strengthen the integrity. At the same time, the mortar can enter the reinforced pores and cracks under the high-speed concrete spraying state, so that the original structure can be restored to a certain extent.
It is suitable for masonry wall cracking reinforcement, brick and concrete structure layer wall reinforcement, seismic reinforcement, accident treatment and other projects.
