Abstract

The invention relates to a solid-waste-based maritime work repair material and a preparation method thereof, in particular to a method for preparing the solid-waste-based maritime work repair material by utilizing industrial solid waste, and relates to the fields of physical chemistry, solid waste reutilization, environmental protection and the like. The maritime work repair material is composed of red mud, nickel slag, sulphoaluminate cement, rubber powder, limestone powder, fiber, silica fume, a curing agent and an exciting agent with a mass ratio of (30-60):(10-25):(10-25):(0.5-1.5):(10-20):(0.7-1.3):(4-7):(1-5):(5-10), and the total amount of the components is 100 percent. The maritime work repair material has the characteristics of good seawater erosion resistance, strong bonding capacity and the like, and is suitable for maritime work repair engineering such as cross-sea bridge pile foundation repair and the like.
