Descrição: The subject of research is expanded-clay concrete with additives of ground granulated blast-furnace slag, silica fume, superplasticizer and air-entraining admixture. The heat release of concrete is investigated depending on the concrete composition (cement, water cement ratio, expanded-clay), additives (slag, silica fume) and admixtures (superplasticizer, air-entraining agent). This study is a part of research on the design concrete mixture with strength class C35/45 and high workability for 3D printer. It was confirmed that the cement content and water cement ratio impact on the integral value of the heat release per unit mass of cement. This value decreases with increasing cement content. The reason for this is that the heat generated by concrete, with constant W/C and other equal conditions, increases linearly with increasing the cement content.
