Abstract:

An unfired foamed-in-place two component insulating refractory and the method for preparing the same. The composition is composed of hydraulic cement, water and an acid, though it can also include an aggregate and/or fine grain inert filler. In the process, the dry ingredients are mixed with the water to form a slurry and thereafter the acid is added to the slurry and passed through a passive mixer before the acid-slurry mixture is discharged and allowed to foam and set.
