CSW waste units were broken, crushed and milled to reduce their particle size. These particles were characterized by scanning electron microscopy (SEM-EDX), laser granulometry, X-ray fluorescence (XRF) and X-ray diffraction tests (XRD), and were then used to replace 0¿50 wt.% PC CEM I 42.5R in pastes and mortars. Workability of the fresh mortars was assessed by the flow-table spread test, and the mechanical properties and microstructure (thermogravimetry, SEM-EDX, XRD and Fourier transform infrared spectroscopy tests) were investigated in samples cured at 20 ¿C for up to 365 days. No significant workability variations were observed with increasing waste contents and, although pozzolanic activity of CSW was relatively slow, it improved with the curing time, and mortars prepared with up to 25 wt.% ceramic waste satisfied the requirements established for other pozzolanic materials, such as fly ash.Reconocimiento - No comercial - Sin obra derivada (by-nc-nd)Ceramic wastePortland cementPozzolanic activityMicrostructureCompressive strengthINGENIERIA DE LA CONSTRUCCIONArtículo10.1016/j.bsecv.2021.05.006Abierto09.- Desarrollar infraestructuras resilientes, promover la industrialización inclusiva y sostenible, y fomentar la innovación11.- Conseguir que las ciudades y los asentamientos humanos sean inclusivos, seguros, resilientes y sostenibles
