ABSTRACT:
Incorporation of solid removable aggregates into powdered cement which later completely dissolve, evaporate, volatilize, or melt leaving voids in the cement composition is discussed. Cementitious articles are prepared by manipulating powdered hydraulic cement or cement paste compositions into mechanically self-supporting structures of a predetermined configuration and thereafter hydrating the hydraulic cement compositions without mechanical mixing of the cement and water.
