Non-slumping, pumpable castable and method of applying the same

摘要: An essentially non-slumping, high density, low moisture and cement castable composition, consisting of a tempered, pumpable first component having density at least 120 pcf containing the solids refractory aggregate, calcium-aluminate cement, flow aid, deflocculating agent, water, water being present in lowest amount sufficient to achieve consistency tempered component, flocculating agent as second be added said time installation an prevent falling or slumping composition once it has been applied. The invention also includes method applying such through spray nozzle which is just prior its application nozzle.
