(57) The invention relates to the field of construction. A method of manufacturing articles with interconnecting voids using a concrete mixture comprises: charging a mold with void-forming bodies made of ice such as to provide for contact between said bodies; feeding water at a temperature of 1°C - 10°C into the mold to wet the surface of the bodies until they become joined to one another; continuing to feed in water to increase the contact surface between the bodies by crystallization of the water; removing the remaining non-crystallized water from the mold; feeding a concrete mixture into the mold to fill the voids between the bodies; holding the molded article until it is ready to be released, and then thawing the mold and extracting the article therefrom. The invention makes it possible to increase the number of voids in an article and to enlarge the cross-section of the channels connecting the voids.
