A method for placing a thixotropic low-cement castable refractory material without the necessity for forms. A low-cement castable material is mixed with a measured amount of water then is pumped hydraulically through a hose to a nozzle assembly. Compressed air and a cement setting agent are added to the mixture at the nozzle. The addition of the setting agent at the nozzle overcomes the
