Super Powerhouse (Keene)

Super Powerhouse was an insulating cement that later came under Keene.1,2 Keene's report published by the EPA in 1990 describes two versions.2 It says a Military Formulation of Super Powerhouse Cement was produced from 1957 to 1971 by companies the report abbreviates as B–H, BEH and KBPC, contained 5% chrysotile asbestos, and was developed to conform to government specification.2 Keene says this version was manufactured and sold exclusively for U.S. government military installations.2

Keene describes the commercial formulation as being without asbestos, and says it continued in production.2 Both versions, it says, were dry mixtures containing spun mineral-wool, hydraulic setting binders, clays and other ingredients.2 Asbestos was removed from the military formulation in 1971, according to Keene.2

An insurance company's 1981 list of asbestos products, compiled from other companies' answers in lawsuits, lists Super Powerhouse cement under Keene as made from 1960 to 1971, with Baldwin-Ehret-Hill in its note column and 5 in the column read as percent asbestos.1 That list does not say which version it means.1
