The components of concrete infrastructure deteriorate due to some reasons in terms of sustainability. Due to these deterioration, the research on the production of high performance repair mortars has increased rapidly. In order to produce high performance repair mortars, two different nanomaterials and fly ash with replacement percentages of 0.5, 1, 1.5, 2 and 55% respectively were added to concrete mix in this study. 50 mm cube samples are prepared with these mixtures for compressive strength in 1, 3 and 7 days. It is observed that the highest compressive strength of samples with nano aluminate and nano calcite is in 1 and 0.5% in 7 days respectively. When nano materials are compared with each other, the highest compressive strength of sample with nano calcite (0.5%) is 56.69 MPa in 7 days and the lowest compressive strength of sample with nano calcite (2%) is 19.23 MPa in 1 day.
