Self flowing refractory castables study of the hydraulic

Refractories are enabling materials in that their primary function is to facilitate the production of other materials such as metals glasses petrochemicals and cements. They have enabled the utilization of heat to make materials since the Bronze Age. Although in recent years a number of studies concerning the many complex variables that determine the rheologic hydraulic and ceramic

Refractory castables are a homogenous mixture of the refractory aggregates and the binders. Mostly cement is being used as a binder phase for the castables. The addition of cement also provides flow properties and leads to easy installation of the cement bonded castables usually reducing skilled labour.

A method of repairing damaged hot refractory linings in high-temperature vessels includes forming an opening through the outer shell of the vessel proximate to the damaged region of the hot refractory lining and introducing a refractory material into the damaged region. The refractory material is rapidly injected in a sufficient amount to effect complete filling and is fast curing to
