Background

The sprayed concrete is concrete constructed by a spraying method. The sprayed concrete has two construction methods of dry mixing and wet mixing, and a dry mixing method is generally adopted. Cement, sand and cobble with the maximum grain diameter less than 25 mm are mixed according to a certain proportion, and then are put into a sprayer, and the dry mixture is conveyed to a spray head along a pipeline by compressed air, mixed with water and sprayed onto a working surface at a high speed of 40-60 m/s. The wet mixing method is to mix the raw materials with water in advance and spray the mixture. When the sprayed concrete is constructed, the cement particles and the aggregate are mutually impacted and continuously extruded, and a smaller water-cement ratio is adopted, so that the concrete has enough compactness, higher strength and better durability.
