The use of clays consisting of phyllosilicates, quartz and carbonates as building materials dates back to ancient times. Clays that have been calcined and have acquired pozzolanic activity form an important group of binder materials. In this context, various properties of cement mortars produced with bentonite and sepiolite clays calcined at 850 ºC were investigated depending on the amount of nano silica usage. 360-day flexural and compressive strength tests were carried out on 40x40x160mm cement mortar samples produced by reducing and replacing the clays to be used in the study 0%, 10%, 20% by weight, and nano silica 0%, 0.5%, and 1.0% by weight. According to these results, the highest flexural strength of cement mortar was 1.0% nano silica, 10% calcined bentonite and sepiolite ratios, respectively; 9.75 MPa and 9.47MPa; compressive strength; 58.41 MPa and 56.93 MPa were obtained.
