Abstract
An inorganic hydraulic material composition containing reinforcing short fibers is sprayed without breakage thereof, by fluidizing reinforcing short fibers in a blast of compressed air, by blending the flow of the reinforced short fibers fluidized in the blast of compressed air with a dry mixture of an inorganic hydraulic material such as cement with an aggregate such as sand in a dry blending region, by introducing the resultant dry blend into a water-mixing region, by mixing the dry blend with water, and by spraying the resultant wet composition through a spray nozzle.
