Abstract
A cementitious composite material exhibiting a unique combination of high strength, vacuum integrity and thermal properties. Objects made of the material may be cast from mixtures in which a major constituent is a filler which consists of stainless steel particles of particular shapes and sizes. The cast objects are characterized by the absence of a continuous network of interconnected pores and by the presence of a tobermorite phase in the material.
