Zusammenfassung:The invention relates to a process for producing unfired masonry blocks, in particular unfired bricks (14), characterized in that- forming a raw material mixture by mixing fired ceramic powder with clay and/or clay-containing subsoil such that the fired ceramic powder is at least 15% by weight of the dry matter content of the raw material mixture and the clay content is at least 20% by weight of the dry matter content of the raw material mixture,- creating a mouldable mass by setting the moisture content of the raw material mixture optionally by adding water, and- the mouldable mass is moulded and pressed.The invention further relates to an unfired masonry block (14).
