ABSTRACT:
A process for forming a hollow cast structure of cementitious material using a hollow mold having a predetermined surface geometry corresponding to the surface geometry of the structure to be cast. The cementitious material is an admixture of hydraulic cement, water and particles of aggregate containing presized, inorganic filler particles having a maximum size of about 50 microns in a predetermined proportion to the hydraulic cements such that the admixture is substantially nondilatent and thixotropic. The admixture is fed into the hollow mold against the predetermined surface geometry from a feeding device separated a predetermined distance from the mold surface while simultaneously rotating the mold relative to the admixture.
