Abstract
An essentially non-slumping, high density, low moisture and low cement castable composition, consisting of a tempered, pumpable first component containing the castable solids and consisting essentially of a refractory aggregate, a calcium-aluminate cement, a flow aid, a deflocculating agent, and water, the water being present in the lowest amount sufficient to achieve a pumpable consistency of the tempered first component, and a flocculating agent as a second component to be added to said first component at time of installation in an amount sufficient to give the castable a dried bulk density of at least about 120 pcf.
